that guy looks like a Russian mobster
Cousin! Let's go bowling!
The Reptilian Wizard Lizard Fuck off Roman
Bonifilio Soto more like viktor from brat
xyleu2 yes, it sure does! ; xp
did you came here to see how the guy looks!!!!?????
Great information! The whole video I had multiple "Whoas!" and "Dudes!".
I loved this! Please make some more episodes featuring other planets and moons in the solar sisterm :)
this made MErCURIOUS.
Can you do a video just like this about Venus?
If i took a house fortified by heavy ass insulation and metal barriers and landed on the ice patch could i live there? Assuming its controlled atmosohere and food etc
... I'm just wondering... but would it theoretically be possible to at some point in the future reduce industrial production costs by outsourcing heavy duty machinery to smaller planets and thus greatly reducing power requirements for some processes due to lower gravity and/or a variety favorable conditions.
I know that transportation will probably make it unreasonable...
what a handsome host
how much bigger is Mercury compared to Pluto?
if it is not much bigger than Pluto would it still be a normal planet or would it be a protoplanet?
just something I have been wondering.
Hmm. I would have thought that Mercury would have very few craters... Considering how the most powerful gravitational field generator in the solar system (Sun) is right next door.
Dig into the crater and live there! System colonization here we come!
What is it like on Saturn and Pluto?
If it's 3 times closer to the Sun then why is it 6 times brighter, shouldn't it be the 3^2=9 times brighter?
This is because the numbers given in the video are just rough approximations.
Mercury has a relative excentric orbit compared to Earth. Taking the orbit characteristics of Mercury from Wikipedia, the brightness of the Sun on Mercury varies between 4.6 times and 10.6 times the brightness of the sun on Earth.
Also brightness is hard (see www.cv.nrao.edu/course/astr534/Brightness.html): The disk of the sun would appear as bright on Mercury as it would on Earth to a human observer, the area of the disk would be just bigger compared to earth.
No it because of the way you work out the volume of a sphere using its radius if you do the maths you can work out the difference in luminosity
Strictly speaking, Reid was talking about the Sun's APPARENT size as seen on Mercury, not its brightness (@0:45)
So there's a crater on Mercury the size of Texas? There's one on earth too. It's called Texas...
Boom! Boom!
Zing!
There's another one quite close to Texas, its called the Gulf of Mexico. Not a joke, fyi, its a legit crater
Damn! Shots fired!
Magmafrost13
the Gulf of Mexico is not a crater basin. You might be confusing it with the Yucatan crater, which is nearby. However, the size difference is immense. The gulf of Mexico simply formed because of plate tectonics.
So there are small relatively habitable locations on Mercury that could be used for manned exploration given the right technology of ingress and egress. That could make a really cool platform for close solar observation.
i love you for using Celsius
***** Not really.
it all depends where you live
Jus10Ed yes really
Jus10Ed Try doing any physics or engineering problem with the English system. I dare you.
Cuckoo Phendula I did; all through school. But all I really meant is they're both equally arbitrary. Only Kelvin starts at an actual zero.
Do other planets too! Its quite fun to learn things of our solar system and its planets.
Marten Homma ya do Uranus.
why do uranus has hair ?
Fun facts :
- Mercury's gravity is roughly the same as Mars' since the planet is very dense.
- There are 2 moons bigger than Mercury: Ganymede and Titan. Still those 2 are not very dense and they have even less gravity than our Moon.
2:00 What on Earth ( I mean Mercury) is an Exposhere?? A typo, that's what it is.
+matt8863 I was wondering about that
The nice man on the screen said exposphere.
Ah, a trypo! Perhaps I'm not drunk after all.
Our outer atmosphere
+Matthew Williams An outer atmosphere created by permanent markers
**squints** - is this Wolverine's brother?
also, he pronounces "Mercury" different at different times, which he's done in other videos with other names and words. maybe i should keep a log... (commander Riker does the same thing)
So if Mercury swings from very hot to very cold temperatures from day to night, there must be areas on the planet that are sort of temperate during dawn and dusk, right? Maybe if we land on Mercury someday, we could pick one of these "dusky" spots to land and constantly be moving at the same speed the planet turns so we always stay in the... wait for it... TWILIGHT ZONE.
Or just on it’s poles
I am sensing a mini-series that will eventually include "What's It Like On Venus?" and so on >:3
I'm all for it.
Support
Can't wait to discover how would be to live on Terra.
Terraria*
OK I meant Terra is like how it is on Earth in fact, Terra is just another of Earth's names.
Hmmm. With a day that is 58 Earth days long, we should be able to land a rover on the dark side of the planet. It would have about 29 Earth days to explore before the sun rose and fried it. Power would be an issue.
Landing safely would also be a concern. The Chinese put a rover on the moon, but Mercury has more gravity, and doesn't have Mars' atmosphere to slow the craft down with parachutes.
If there really is a deep crater at one of the poles, we could put a rover in the crater and it could send us data until it broke down from normal wear and tear. Power is still an issue. We would also need to have a satellite, or a couple of them, in an orbit that would pass over the rover's position so we could communicate with it. Would the satellites be able to protect themselves from the sun so close to it? I think we have technology for that.
Here's a thought. Send two packages. One contains the rover, a second contains a shelter. The shelter would be a highly reflective igloo. When dawn is about to break, the rover drives into the shelter and sits tight for 29 Earth days till the sun goes down again. The entrance would face either north or south, so no direct sunlight would hit the rover while it's napping. The shelter could double up as a charging station and a big battery. It would charge up during the day (wouldn't take long) with solar panels. At night, the rover could scout about and go back to the shelter/charging station when it runs low on juice. The charging station would probably be drained long before the sun came up again, so we would have to be satisfied with the rover collecting data for only a couple of Earth days out of every 58.
Definitely and engineering challenge, but it would sure be cool.
The igloo and the rover. Nice idea.
Depending on the thickness of the exposphere, couldn't you just have the rover moving underneath the reflective "sun hat"? As long as heat conducted through gasses in the air isn't an issue, anyway... or through the ground....
I really like your ideas but i'm not sure the igloo idea would work. its not easy to make something that can reflect out heat very well. unless we can make something very effective, the igloo will reach 430 slightly slower than the ground. and even if we did manage it, the rover and the igloo would be siting on a very hot ground. we simply cannot make something light that can stay cold for a mouth.
Heat transfers in three ways: convection, conduction and radiation. Since Mercury has no atmosphere, convection won't be a problem. The igloo is to protect the rover from radiation from the sun. I've no idea if the technology exists to make one that would protect a high tech device for 29 days. I leave that for the engineers. If we assume that the igloo works perfectly, then that leaves conduction. Geologists would have to determine how well the ground conducts heat. Normally, stone is a pretty good insulator, but imagine a stone oven that was kept running at over 400 degrees Celsius for a month. Iron is a good conductor, so if there is a lot of iron in the soil then it might not insulate so well. Maybe it can be done, may be not. Worse case, we could put it there just after dusk and it could explore until the power runs out, or the sun comes up, whichever happens first.
I'm not even sure if we can safely land there. The gravity on Mercury is greater than it is on Mars, with no atmosphere to slow the descent. We would have to use counter thrusters like we did on the moon so many times. The landing process would all have to be automated because the distance and speed of light would slow communications.
I guess that's why NASA hires all the smart guys.
I think, that when Sun is between earth and mercury, no communication can be made. So the time frame, when you can actually do something, can be even shorter.
can we dig up the metal inside and build a space fleet
I think we might have stumbled onto something...
Even with the weaker gravity, we don't have what it takes to dig that deep into a planet. There's plenty more ores within our own planet. We don't go after it simply because we can't.
Novumic Another question: If we were to dig up all the iron, ice and rock, literally eating away the whole Mercury step by step - how this will affect the Solar System? Would some planets' orbits move closer to or further from the Sun?
Novumic
Agreed; as you beat me to the punch! The core may be relatively closer to the surface but its still just about as deep as our crust is and we haven't even dug anywhere NEAR past that yet. We'd be better off harvesting asteroids for their material.
KinRedysko No. There would be essentially no effect on the rest of the planets whatsoever.
"What's it like on Mercury?" "Hot." Video ends.
etherraichu Did you watch the video cause he debunked that? Or is this sarcasm? cant tell
etherraichu
Venus is hotter, she's the Roman goddess of Romance (heehee)
@@niaschim Hah!

I feel like the comparisons made to the moon were odd as not many people have a solid understanding of the moon, while comparison to Earth were more relate-able because you know... most people had a chance to visit Earth for a while.
I was just there last week actually. The people can be a-holes depending on where you land, but it is, overall, a nice planet
YingofDarkness
the moon sure is a nice planet :D
Sylvus *didnt get the joke*
YingofDarkness Martians are more tolerable than Earthlings though. I suspect that's because Mars is a more varied planet.
I'd argue that anyone with even a passing interest in science is aware of the moons basic properties.
Because Mercury's orbit is so eccentric, the sun's apparent diameter varies from about 2 to 3 times its apparent diameter on Earth and its total brightness varies from about 5 to 10 times its total brightness on Earth.
Hey there humanity,
What's is like on Mercury?
I'm a million miles away
But tonight you shine so pretty
Before the stars.
Our Sun can't shine as bright as you
I swear it's true
I swear it's true
EDIT: Why did I type this?
I want this guy to be my college professor in science.
Obviously Venus is hottest, if you know what I mean :p
TOO HOT
He sure is!
And too cold
Crohniponi You mean he's "cool"?
***** she was invited and said yes but then no.
***** Hot damn.
What is it like in your chest hair?
DUDE.. you're doing a great job here.. awesome videos! big fan of all SciShow! :)
but try not over-acting.. it's unbecoming.. you're a pretty cool dude just being normal.. :)
keep up the good work!
maybe we should call mercury iron. get it because mercury is a metal and the planet is mainly made of iron..... no just me n/m
Hmmmm, sounds perfect for a vacation! xD
Were we watching the same video? >.
this is supposed to be a serious, info-entertainment channel.
and here i see, some one some showing more chest hair, then what i have on my head.
Would be interesting if we one day could travel there, mine a hole in Mercury and build a base down there. Then proceed to mine all that metal. Would give us enough materials to build huge space ships, space stations and lots of smaller ships. The sun will eventually devour that planet, so might as well make as much use of it as possible.
Yeah, the sun will eventually devour Mercury.. along with Venus and possibly Earth more than 5 billion years from now. Not to mention that the steady increase in the sun's luminosity and heat will most likely render Earth an inhospitable, sterile, barren wasteland of nothingness in only 1 billion years. So all life on Earth will be annihilated long before any planet is swallowed by the sun.
binky2819 it’s more like 2-3 billion years that the sun would be too hot for life on earth
Plus you would have access to much more solar energy to power a mining & manufacturing base on Mercury!
Why is the sun only 6 times brighter there? If it’s 3 times wider, it should be 9 times brighter, right?
Please do one for every planet!
Is hank threatened by your manliness?
This was extremely interesting! Do all the planets in this solar system! :D
Bout to train like Goku on Mercury
"Have you ever wondered what it's like on my noticeably hairy chest?"
Did he just call exosphere 'exposphere' ? I can condone the spelling mistake in the video which was 'exposhere'. I suppose the p got misplaced.
But what's with making that error verbally?!
No idea
Reid is a really great host. We see him fairly often on this show but a little more wouldn't hurt.
I'm guessing something is a bit different with the lighting this time...or it's hot under that light and he's been standing there a while. The glow is quite a bit more noticeable than usual.
God, Reid is so unbelievably handsome...
my first time watching scishow space and I chose this video..
I was surprised by the deep voice..if only he spoke slower, I think I can think of the video as something like
*imagine reading this in his voice*
"An Adventure into Space"
Damn... His voice is so fucking awesome
Thanks for implementing the metric system and Celsius people. Finally an american science show that also makes sense to the non-americans i.e. the rest of the world (Yes even UK uses the metric system). Which makes me wonder, why are we still using nautical miles and feet on sea and air, is it because of tradition? Humans like to complicate their lives.
science host, says "acrosst" .... are you TRYING to rustle jimmies? because it's working.
Mercury you little sumbitch Ill find you.
- A backyard astronomer.
Where's the host from? I like his accent.
I'm a little surprised that the surface isn't just molten in the side facing the sun. Sort of sounds like the Trippe-Max Prison planet, Crematoria in Chronicles of Riddick.
450 degrees Celsius isnt hot enough to melt rock
And like Crematoria, you gotta avoid the surface at day or night. Only go outside at dawn and dusk.
You left out the coolest part of Mercury: the rotation is at just the right speed that you could comfortably walk at the same speed as its rotation, meaning you could be in either perpetual sunrise or perpetual sunset. Or preferably just before or just after each so you aren't fried to a cinder. :)
Just one more button on that shirt man... just one more
You forgot to mention that the caloris basin also created a mountain ridge at the other side of the planet, kinda like hell and purgatorium from the divine comedy.
I actually give thumbs up to videos from sci show before I even play it.
"It's expo-sphere"
And then they spell it "EXPOSHERE"
I'm no grammar nazi--but seriously, people.
“Exposphere”
Did you mean *EXOSPHERE*?
shouldn't the sun appear 9 times brighter, not 6 times brighter than on earth due to the inverse square law?
I hope you do a series of "What's it like on...?" with different astronomical objects, would be great! :D
That chest hair though...
Sorry :p, very interesting though.
I love that these videos include sources for their information.
What's it like on Uranus? (seriously...)
Potasium? so inhaling mercuries air is healthy af..
Dat chest hair though! You remind me of the owner of an Italian restaurant
Super Superb!! Super Superb!! Super Superb!!
Super Thanks for Sharing!!
Please do one video for each planet and important moons like Titan!!
i like it how he says ONLY 58 Million km from the sun
Nice video, it really kept me interested, and very informative.
do every planet in the system this way, exept earth already been there
"Exposphere"? Shouldn't that be "exosphere"?
+Matthew Ferrie You are correct.
Yeah
it is a joke for people who have been around since 100 subs
+Matthew Ferrie no, it's the layer in the atmosphere that molecules go to sell things like jewelry and crafts.
Exposphere? Not exosphere?
What's waiting under the clouds of jupiter? A ball of hydrogen so compact that it has taken on a metallic nature.
Metallic liquid hydrogen
surely 9 times brighter not 6 times brighter? Inverse square and all
he said Approx
i like this guy
Looking like Hunter S Thompson here lol
You should do this for the rest of the planets!
My pet theory is that Mercury was once bigger but got it's crust blasted off leaving the core to make up most of its mass.
***** Well, for a "pet theory", it's been taken pretty seriously. See Benz, W.; Slattery, W. L.; Cameron, A. G. W. (1988). "Collisional stripping of Mercury's mantle". Icarus 74 (3): 516-528.
Actually I think that is the prevailing theory about Mercury, so you got it!
No.
well Mercury did lose a lot in width
1:10 "So the planet ends up experiencing roughly THREE DAYS for every TWO OF ITS YEARS."
That is incorrect. A day on Mercury lasts 176 days, so a SINGLE DAY last as long as two of its years. While the planet takes 58 days to rotate once on its axis (a sidereal day), that is not the same as a solar day - i.e. the time it takes for the Sun to return to the same place in the sky.
Yeah it is it's exactly the same thing. Earth takes 24 hours to rotate around its axis and the day lasts 24 hours.
No it absolutely is not. The Earth takes 23 hours 56 minutes and 4 seconds to rotate on its axis. It takes 24 hours for the Sun to return to the same place in the sky. This is the basis of a day, which results from Earth's rotation and its orbit around the Sun. Not knowing the difference is an amateur mistake. And I should know since I made it, when I was an amateur :)
You should make a series out of this do all 9 (I dont care what you say there are 9) planets.
They're unlikely to do Earth, since that's the planet we live on, and they've probably already explained a lot of it on their regular channel.
Would the sun influence the gravity pull at all since its closer to the sun?
like if the sun is in the sky... your body will be lighter by being pulled off the ground by the sun
or if its night ...your body will be heavier by being pulled towards the planet by the sun on the other side
I doubt it but I'm still curious :P
Fuck, i already liked the video.
Please, answer this to me:
Why does titan have a weaker Gravity than the Moon, in spite of having so much mass than the moon.
Kevin Velásquez Lighter elements on titan
+Kevin Velásquez Because it's bigger.
Hairiest scientist show host ever
Damnit man! Grab a beer with me!
Dancing on saturn. That makes sense. It's only a gas giant.
spelled "exosphere" wrong
Whats it like on Neptune? Or Pluto, since Pluto is still a planet. Whatever those spacey-wacey people at NASA that it's not, they are soo wrong.
Actually the IAU, not NASA.
MLP Brent As if you know more than the scientists at the International Astronomical Union. Your definition, that you probably pulled out of your ass, is just solely based off of the fact that you like the planet, which is less accurate than the real definition based on fact.
*Random RHCP reference*
mercury is obviously the best candidate for colonization. we can bury ourselves into the poles deep underground for stable climate. the solar power is infinite, and there is amble time to move mobile solar power platforms as the day is slow to change. whereas mars is devoid of any sources of easily obtainable energy, and venus, while attractive in size and gravity, simply has no hospitable surfaces to live on, not at the poles, nowhere.
not only ,, but massive amounts of aerobraking using venutian atmosphere are available in both directions going towards mercury and away from mercury, so even though the trip there may take longer than mars, there are methods of dramatically lowering the deltaV required to get to mercury and back to earth. finally, if you're an exotic believer, we can use venutian atmosphere as a gas source for collecting propellant on the missions to and from mercury. mars has so so so many problems. aerobraking mars is hard and we've lost missions before, because the atmosphere of mars is too thin for effective aerobraking . venus is perfect as a gas bag on the way to and from mercury .
I like SciShow Space, but I sure wish Hank was hosting it. I would enjoy it so much more.
Awesome work as always!
LOOL "created over 40 million years ago.... Hahah... No really that's the funniest thing I've heard for awhile.
0:47 The intensity of sunlight on Mercury's surface ranges between 4.59 and 10.61 times the solar constant (1370 W/m²).
Wouldn't it appear 9 times brighter because of the inverse-square law? (assuming 58 :150 roughly equals 1:3)
Ok just a curious question.
Why is it that we compare the size of the moon and mercury to countries or states; that is such an understatement. When you understand that they are spheres and countries take on a measuring unit of surface area since its more or less 2d (when you "compare" via map), while planets and moons are in spheres.
I was shocked when I googled the total surface area of mercury. Did the math, to find out, that if you could walk around every square km of mercury, it would be the rough equivalent to walking all of North America, South America and Africa (72.77 million Km^2 juxtaposed with mercury surface area at 74.8 million km^2); from another perspective all of Eurasia and South America (Combined to be 72.6 million Km^2).
Sources: All data for surface area were taken from typing Surface area of ____ in google and using the info card. (I am not sure if these measurements include mountains and craters)
Isn't this a HUGE misconception people can have. I never understood the scope of size till I saw it this way. Its just not a very scientifically accurate juxtaposition, in my opinion. Perhaps I am just persnickety but I feel like this one is a very important distinction.
It rotates EXACTLY three times for every two revolutions, which is kinda awesome) 58&88 days are rough numbers.
Great video! This was a great way of explaining what it would be like to stand on Mercury, and the delivery reminded me of Neil DeGrasse Tyson, which of course I mean as a huge compliment! Two suggestions: wardrobe check: the collar had a 70's porn vibe. And stage makeup: it's a thing. Cameras are not kind to shiny faces, as I know all to well being very oily skinned myself!
6-times brighter? Why? From 1/3 the distance, the Sun would be 9-times brighter, not 6-times…
