2014: "Makemake's lack of a moon..."
2016: MK2 officially confirmed.
deet0109 They're already on MKX buddy.
Ba-dum chhhh!
Lol true
Bother, you beat me to it.
Lollll😂😂😂😂
deet spotted
Makemake does have a moon. We just discovered it in 2016, and this video was made in 2014, so, you're off the hook
Also, we MAY have found evidence for a Object bigger than Mars in the Oort Cloud, so this video is kinda outdated...
yup MK2
MK2
I guess he's right
Same can be said about the picture for Pluto
This video was so incredibly educational that I was able to share it with the students we work with as a very concise explanation of what dwarf planets are, what dwarf planets there are in our solar system, and why it is so hard to categorise our neighbours.
Wow! Castor Quinn this blows my mind. Thanks you so much. I hope your students found it beneficial. :)
Me too. We weren't thought astronomy in school :(
:) No thanks to school though. Thumbs down to the irish school system. Thumbs up to post-school internet learning.

Just a note (that you probably should put it there) now that we have an accurate measure of Pluto, we do know Pluto is Bigger than the other Dwarf Planets. Also, we did classify Pluto as a planet and never had this weird conversation about Dwarf Planets until 10 years ago, because we really thought it was about the size of the earth and over the years we just got better at measuring it.
Pluto is bigger, but not more masive
Here's more proof that I learn more on youtube than at school XD
Amen, to that! Voluntary learning ftw
thats why im homescooled now if we learned something cool chanses were i alredy knew for like over a year and in more detail
+Galaxy Gazer Music you learn more from the library in the childrens section
+Galaxy Gazer Music yep
+Galaxy Gazer Music that means no more school I'm in 3rd grade and I hate my school(Jason lee)
Eris has now been discovered to be smaller than Pluto.
Damn! This was just packed full of very useful dwarf planet information! I love dwarf planets, so this was right up my alley. Another very awesome video!
Thank you, good sir! Those little dwarves are indeed very loveable
What a fascinating piece of work. You made the once boring totally absorbing. Well done.
I love how he mentioned that there may be mars sized dwarf planets out there beyond the Kuiper Belt and now astronomers are theorizing there's an actual 9th planet out there beyond the Kuiper Belt.
This is the best dwarf planet related video i've seen. Gratz, man!
Thanks, that really does mean a lot. Glad you rate my vids :)
02:28 I guess some people will not get the sarcasm, for that people then: This is sarcasm!!
A native English speaker pronouncing the Dutch 'ui' correctly. Here, have all my likes!
Pretty sure he's bilingual, speaks Irish as well.
And if he's not, then he at least is a linguistics enthusiast and has learned how, along with other sounds.
@Markerz 321 Nope! Check out the word "ui" on forvo.
So we've reclassified the planets. Can we please do the same thing about the moons? It's unusual to say that both Titan and Deimos are equally moon like.
The moon status only means that they are orbiting other planets as natural satellites, instead of orbiting the Sun
+Sean Hiseman I think there is some limit, probably whatever we can see and observe.
+Sean Hiseman Yes, technically by definition grains of dust count as moons. And yes, that could do with some improvement.
+Sean Hiseman anything that orbits a planet is a moon hence the name satellite, objects like the ISS would still be a moon but its artificial hence the name artificial satellite so in reality Earth could have millions or maybe trillions of moons.
that is true, but the definition of a moon is a 'large' object that orbits another object that isn't a star. By large, I mean larger than say a house... because if you say all things orbiting planets are moons, then Saturn's rings are made of BILLIONS of moons.
I kinda like the fact that this video about dwarf planets came out 5 years ago is more educational about celestial bodies than some high school science classes today. XD
This video suggests it's possible that, statistically, there could be a Mars size planet out side the kuiper belt. Last year NASA, or another organization, announced a theory that there is quite possibly a planet sized object beyond the belt. This is due to changes in the belt that has to be caused by a gravitational effect.
I still have a book where Pluto was still listed as a planet.It was printed in the same year as it was later removed.

Yeah, he's Irish. They drop the h from th sounds.
This comment was made when i was 13 lol i realise what accents are now
Best video about dwarf planets explained the way I like. Thank you!
Your videos deserve way more views. Keep up the great work!
Glad you think so. I hope one day they do get more views. :) Thanks for watching. Much appreciated
@@Artifexian you got 167K subs
I'd really like to see this topic revisited by you. There have been so many revolations and new discoveries in this field, would love to see a video from you about these new discoveries.
This one of the best videos I've seen so far about the Pluto reclassification topic. Well done
Cheers :) It does seems to be going down well.
coming back to this is great. Recent evidence of both a mars sized object and a 10 Earth mass object.
Moral of the story: reality is under no obligation to conform to the boxes humanity puts it in.
+Artifexian, you produce great informative and entertaining video content. I may have already said that in other comments, but let me tell you that once more - JOB WELL DONE!
it's amazing to think we know all of this just by looking at the sky, even as we are confines to earth. Objects at distances unimaginably far away discovered just by looking at the sky
Eris is smaller than Pluto. It’s just more massive.
At 5:22 you even put Pluto at 2,368km and Eris at 2,326km.
smallest than the five dwarf planets
*draws 4 dwarves*
meant the other 4
The fifth is Ceres, which was already drawn.
Good stuff, man! I did not know about Sedna, let alone the fact there could be 59 more of them out there, haha
I know it blew my mind too. Cheers for watching
Dear Pluto
Hello it's me Ceres, I was downgraded from a planet to an asteroid
over 150 years ago so please, stop whinging about you not being a planet any more
Love Ceres
OOF
pluto was foudn to be slightly larger than eris when new horizons flew by in 2015
but this is 2014 so
whatever
I wonder...
if in the future we can terraform Mars by bringing Ceres to collide with Mars; filling it with water.
Pluto the dog was named after the dwarf planet. The first instance of Pluto as the name for the dog came several months after the discovery of the then-planet.
Pluto the dwarf planet was named after the Roman God of the Dead (also known as Hades, the Greek God of the Dead.)
I think he said it as a joke. I kind of get a sarcastic vibe with it.
Properly. It just annoyed me a little, is all.
5:13 Nice Easter Island drawing!
Great series,you really have good explanation
with the discovery of a neptunion sized planet, that really kicked the bag open didn't it.
could you please make a video about how would life be like on a habitable moon on a gas planet's orbit? Like, how would the weather, the tectonic plates, the different cycles like the days be affected? I'm reaaaally interested in that kind of stuff
How does this channel only have 45k subscribers
Because its stupid
*158k
My two favorite things... Astronomy and an Irish accent... I LOVE IT
Planet Nine, baby. The dream is real.
The relegation of Pluto to the status of dwarf planet is one of those things that has never stuck in my mind. It keeps tripping me up.
The sun rises in the east. The earth orbits the sun. The moon orbits the earth. There are 9 planets in the solar system. Even though I remember that Pluto is nor a planet anymore I still think that we have 9 planets.
Makemake does have a moon MK2
Recently discovered though
LOVE FOR PLUTO AS THE 9TH PLANET
YASSS
FYI pluto was named after the roman god of death, Pluto, which is also why its moons are named Styx, Nyx, Charon and Hydra.... though i'd have named Hydra Kerberos.
teutonieth
i know that
Damn this video is so old that there weren’t any good photos of Pluto.
And before 2006 Pluto was declared as a normal planet. Nice video by the way ;)
Was it? The IAU's final definition of what a planet is set on August 24th 2006.
Artifexian Yes, on August 24th 2006 the IAU resolution created three main conditions and pluto failed at it because the mass want enoug.
As wikipedia says : " The IAU further resolved that Pluto be classified in the simultaneously created dwarf planet category, and that it act as the prototype for the plutoid category of trans-Neptunian objects, in which it would be separately, but concurrently, classified."[146]
Wiki also says : "Discovered in 1930, Pluto was originally classified as the ninth planet from the Sun."
For a moment i forgot there are dwarf plantes and when I saw the title and thumbnail I was like where the hell did they find dwarves
Dwarf planet number tree, that's right "tree"
His accent replaces "th" sounds with "t" or "d" sounds
Pluto is the name of the Roman god of the Underworld. albeit its naming was decided by contest and a young girl's choice won, so she could've been thinking of Pluto the dog. but i like to think its the Roman Mythos's influence as the reason it has that name.
5:16 "And about two turds the size of pluto"
Awsome drawing
Perfect.
Sedna has a crazy orbit:
2015 TG 387: Allow us to introduce ourselves
5:28 Artifexian, pluto's size number is bigger than the eris (2.368 > 2.326),and eris is bigger than pluto, you made a mistake
Pluto is larger than eris but eris has more mass
I at first thought you were talking about planets inhabited by dwarves. That xena picture threw me off.
And now we Know Pluto is slightly bigger than all the other dwarf planets, makes me wonder if all those changes would even exist if we did know that before.
No. Eris makes Pluto look like an M&M. If Pluto was called a Planet, then Eris is DEFINITELY a planet. Also there's way more too it than the size of a planet to be classified as a planet.
eris is still more masive, and is only like 20km smaller in diameter, meaning its almost nothing
Juno actually looks like a face? Jeez, I think the universe has a good way of making dwarf planets and asteroids unique... making them look like they have faces or making them look like everyday objects.
And basicly because every planet is not EXACTLY a perfect sphere, the planet I think is the least round is our own, Earth, which is round-...... ish.
When he said Pluto was named after the dog he was kidding it's a joke
In the words of the British schoolgirl who named Pluto (1918-2009) "Mickey Mouse's dog was named after the planet, not the other way around."
I didn't know there were so many stealth puns in the naming of astronomical objects. "Lawless", "Easter"... And who said science was boring?
Pluto was not named after the Disney character, but the god of the underworld in Greek mythology.
This is true. Reddit latched onto this immediately. Had intended that to be a sarcastic remake...but it did not come across like that. This will be included in a upcoming corrections video. I do not wish to propagate fasle info.
Shall be remedied. Thanks for pointing this out.
Hidden in all this debate about Pluto is that the IAU changed the word "planet" from a noun to an address. The definition states that a planet travels around "the sun", not "a star", so homeostatically round objects orbiting other stars aren't planets anymore either.
It would have been better, if they wanted to exclude Pluto, if they would have separated rocky worlds from icy worlds.
I remember hearing somewhere that, since the word “planet” is so archaic and has such an inconsistent definition, it may one day be phased out.
I personally am all for this. If Pluto can’t be a planet, *nothing can!*
There is actually a moon orbiting MakeMake known as MK2, MK2 is one of the darkest things in the solar system.
And Pluto was named after a goddess, and the person who named Pluto was 11 years old!
and pluto being the most iconic dwarf planet
A 160 km wide moon of Makemake has been discovered this week.
We found another object with a Sedna-like orbit. It is called 2012 VP113.
And now Haumea's got rings!
No comment on the real problem with this dwarf planet nonsense? Earth, Jupiter and Neptune haven't cleared their respective orbits either, and would therefore be classed as Dwarf Planets. Yet we continue to call them Planets. As Alan Stern once said: "If Neptune had cleared its zone, Pluto wouldn't be there."
+Jarrah White Ahem... you are extrapolating the meaning of "clearing the neighbourhood" to a logical extreme. _Which is incorrect._
"Clearing the neighbourhood" means that the object is massive enough that everything within an appreciable distance of its orbital zone is gravitationally dominated by that object, and there are no other bodies of comparable size other than its satellites or those otherwise under its gravitational influence.
Earth, Jupiter, Neptune, and the other large planets fulfill this criterion. Earth gravitationally dominates Luna and other objects in its orbital path. Jupiter gravitationally dominates all of its moons and everything in its orbital path. Neptune gravitationally dominates all of its moons, Pluto and its moons, and everything else in its orbital path.
at 5:25 is it your drawing or did you mix up the numbers for pulto's and eris' diameter(or circumference it wasn't clear which), i'm just a stickler for for thing's like number matching up to relative sizes.
Now , I think the dwarf planet makemake has a moon called MK2
Actually, though they are "Dwarf planets" they aren't; they're the Synonym for "Planemos" making them classified as "Planets" because they have gained enough mass to have moons; or is sphere-like in shape.
i like the planet 9 theory :D
Meet Dwarf Planets: The only near celestial bodies (including their moons) that aren't named after Romans (except Earth)
Makemake's moon is called MK2
In Pluto is Mercury the same size as Pluto x3??
UPDATE:
In 2016, Makemake's moon was discovered. It is called MK2.
and the video is from 2014
I guess it'd be a bad time to mention the discovery of planet nine two years after this video huh.
it's funny how they now believe Pluto might be five times bigger than what they though due to the New Horizons probe. I wonder how much bigger the other Plutids are.
Can you update this for planet IX?
Actually it is probably more the size of Neptune (the 9th planet if there is one)
Finally some love for Ceres! #CeresIsAPlanetToo
Ceres is literally almost 3 times smaller than Russia.
@@cantoninacanton Pluto is also smaller than Russia. Russia is a big place.
another question is how did astrophysicists figure out cedna's wild orbit and how can you even calculate an orbit without observing it?
MakeMake does have a mon its called MK2
That orbit though...
How can the shapes of such strange orbits be calculated if they take so long to be covered by the planet/object? For example Sedna's at 6:00, it could be any shape, but they've determined that it's that long and they even calculated the period.
Orbital Physics baby. let me explain. The 2 most important points in an orbit is it's periex (closest approach to the center of mass) and the apex (farthest point from the center of mass). As an object orbits it speeds up as it approaches it's periex and slows as it reaches its apex. Sedna is speeding up, meaning it's approaching it's periex. The angle it's moving at shows it's near the periex. so we just have to do the math of how a object moving at this point, angle, speed, mass, and acceleration, and distance would make it orbit around the mass.
Thank you so much! I didn't think I'd get an answer like this, appreciate it
sedna has streched that long cause of a masive thing pull him out
1. the eliptical orbit of sedna is caused of jupiter and satern pushed the orbits
2.A MASSIVE object like 5-10x bigger than jupiter is out there on the solar system further than the kuipter belt that pulls sedna OUT through the kuipter belt
3. it must be a star or a BIG PLANET
Why albedo of Eris is 0.96, but reflectes only 87% of ligth?
on the video you show Pluto as 2368 km and Eris 2326 km thus making Pluto bigger.
If I were classifying objects in space here is how I would classify them(and in my fictional universe all these things are true):
Stars: Bright objects that make their own light via nuclear fusion
Asteroids: Tiny rocks that orbit independently of any planets but not independently of each other(kind of like how the ice particles in Saturn's rings orbit at a different speed than the planet itself but gravity both towards each other and towards the moons of Saturn makes every particle orbit at the same speed so the ring as a whole has an individual orbit, not every particle)
Moons: Big or small rocks that orbit around a larger planet without affecting the planet's orbit much(so barycenter inside the planet) and that are not in a ring but in either a gap between rings or completely outside the ring system if the planet even has rings
Planet: Any rock(whether it be completely rock(terrestrial) or a rocky core surrounded by gas) orbiting around a star that isn't an asteroid(comets are like icy asteroids) a moon or another star
And thus the term Dwarf planet would be a subclassification of Planet, not a different classification.
And here is how I would define dwarf planet:
Any planet that is smaller than Mercury
So those hypothetical dwarf planets that are 3x, 4x, or even 5x the size of Pluto would not be dwarf planets in my universe. Those would just be planets and thus have all the classifications of planets(a gas dwarf could be of a similar size as Mars)
Eris: Die, Plutato
Pluto: Nooooooo....
*Squelch*
2:30 actually, Pluto was named Pluto before the character Pluto was named.
hiygea is in the asteroid belt and its spherical
Sedna is named like that cause its sad that it has to travel so far
poor pluto... just wants to be friends with the others in the solar system
What do you use for the size comparisons???
with the new horizons mission in 2015, it has been found that pluto is actually larger than eris. But it is more related to Kuiper Belt objects than the actual planets so... sry pluto
Pluto is larger in volume, but we have calculated using Eris's moon that it is more massive.
What I don't get is why Mars, Venus, Earth, and Mercury all have more in common with dwarf planets than Jupiter, Saturn, Uranus, and Neptune, and yet are still grouped together with the latter rather than the former.
Because they have normal orbits. they're also not apart of belts of asteroids.
Dark Pop That really sounds like an excuse they came up with so that we wouldn't have to reclassify Earth as a dwarf planet.
+Ben Thomason It isn't, though. Why aren't we classified as chimpanzees? They use tools like us, they can do basic human actions. They can stand up right? So why aren't we classified as Chimps? It's because there is differences and way more things we can do beyond Chimps.
So for Planets, the same. Dwarf Planets are round most of the time like Planets, the orbit the sun, etc. yet there are things to Planets that Dwarf Planets can't fit into. Pluto has an odd orbit, it's more related to comets. Pluto is also in a lock with its Moon, meaning that Pluto itself is a moon to the other.
pluto is called after the roman name for hades... all planets are called after the roman gods Mercury comes from Mercurus (messenger of the gods), jupiter (the "king"god and ruler of the sky and heaven), pluto (the god of the afterlife and underworld), Mars (the god of war) and juno(ik a moon) (was the wife of jupiter)
It was meant to be taken sarcastically
Pretty decent video, despite some scientific inaccuracies. The IAU definition is very flawed because we are likely to find larger objects the size of Mars way out there, and calling THAT a dwarf planet is not a line I think many would cross.
The fact is that there are way more “Plutos” than “Earths” and “Jupiters” combined. There may be many more in the deep depths of the Oort Cloud and the number of planets is only going to increase. 🪐
Erie is actually smaller than Pluto.
