Why Venus and Mercury have no Moons?
Вставка
- Опубліковано 16 сер 2020
- Mercury and Venus have no moons because of their close proximity to the Sun. Any moon orbiting around them is likely be swallowed by the mammoth gravitational pull of the mighty Sun.
All planets except for Mercury and Venus have moons. In fact, Earth is the only planet to have just one moon; remaining planets from Mars onward have multiple moons, with Saturn having as much as 82 moons! So when most of the planets are inundated moons, why do Venus and Mercury have no moons?
The moonlessness of Venus and Mercury is mostly attributed to their proximity to the sun. Being so close to the sun means that they’re not only exposed to a lot of hostile solar radiation, but also experience the intense gravitational pull of the massive star nearby. For Mercury, the planet is simply too close to the Sun and also too small to have any sustainable gravitational influence to secure a moon in orbit. As for Venus, its slow retrograde rotation makes it challenging for any moon to stay in its orbit.

Imagine that Mercury was the satellite of Venus
If mercury was a tiny bit smaller that could happen
Yes
Then murcury ended up being the second biggest moon
@@polyhedron6834 like the same size as io
No mercury is the moon of the sun
It seems to be an underrated channel despite giving so much useful information in a lucid way.very helpful for students.
Very nice video bro
Most Underrated Channel In YT
I recommended this channel to my teacher, she said its a good channel
Great video, what are the odds that mercury was once the moon of venus torn apart by sun?🤔
Venus lost its moon due to a large asteroid hit her.
Venus' past moon was MERCURY!!! ;)
Did you just call Venus a her?
@@terraformedmars3555no
venus is an object, not something with a gender
@@Pupptart69lolzi mean you could technically call her a her cause of greek mythology it doesn’t matter
Beatiful. I loved.
I’ve heard of an accretion disc in regards to a black hole. Will those accretion discs cause a coalescence?
Great video! One thing though, even if any object, say, our moon, is formed from accretion then why are there different sections like the core, mantle, crust of moon etc.??
And, what determines the size of hill sphere? Thanks! And if the case of Mars' Moons is because they are asteroids, so, when meteors pass through the Earth, then why doesn't it make it a moon??
Core, mantle and crust of the moon are formed because of gravity just like every other planets.
The crust, mantle, and core are formed naturally by the gravitational pull the object exerts on itself. If the object is big enough, it's internal pressure exerted by it's own gravity will cause its interior to be like this. Pressure eventually melts materials (mantle) and then superheat them and in some cases, even turning them into solids again (core). The Crust is product of the materials contact with the colder temperatures of outer space, and the atmosphere is the gases the object manages to attract (which if its too small, the gravity won't be enough to attract gas.)
And the hillsphere is determined by the force of gravity of an object, plus it's distance from another gravitational force.
Awesome. Please make a video on black holes and hawking radiation.
Hi Nitin, we already have them. You can check them here: ua-cam.com/video/fqnmUNzn5N8/v-deo.html and ua-cam.com/video/apkLyf1UyVM/v-deo.html
@@Scienceabc Thanks buddy. You guys are just awesome. Keep up🤘🏻
I bet if Venus suddenly had a moon similar to ours, it would be habitable in 10 years.
No planet changes that quickly
Pluto has 5 moons btw.
But despite being smaller than mercury (and the moon) it is so far away from the Sun that it has better chances at getting moons which in its case theyre all captured Kuiper belt objects. (Fun fact: if you didn't know Pluto and Charon are actually a binary dwarf-planet system. Kinda like binary stars. Pluto and Charon orbit each other; and with their combined gravity, they exert a stronger gravitational pull on their moons. That's why they have four) (another fun fact: Neptune's moon Triton is a captured dwarf planet. In fact, Triton would be the largest dwarf planet if it wasn't for the fact that it orbits Neptune.)
@@TheBlueCreeper- Eris is the largest dwarf planet currently though, being only slightly smaller than the smallest planet in the solar system, Pluto. And before you say “Pluto isn’t a planet”, wasn’t the main issue that started that whole debate in the first place the fact that they thought eris was larger than Pluto?
What if Mercury was Venus moon and somehow got threw away from its orbit and started rotating the sun?
Thats because it did launch and started orbiting the sun ;)
New term: rouge moon!
Whoever threw them out of orbit needs the naughty corner
@@shylock5477
It probably happend due to the 5th gas giant being ejected there was a 5th gas giant but it was ejected due to a dangerous encounter with juipter and that ruined all the dwarf planets orbits and Mercury was no longer Venus moon
@@thecreekcraft3326 tf are you on about? And why on earth did you @ me.. of all people?
Venus does have moons, it has 2, like Mars does. There were nearby asteroids that were considered possible moons since they orbit Venus.
None of the 4 inner planets formed a moon by accretion. Mars captured two, Earth had a collision
I wonder if the hear affects moons or lack of moons
We can have the (TIME MACHINE) ideas
Let's make Venus and Mercury buddies
Best video ever
I agree that mercury is too close to the sun causing it to have no moon but the point that mercury is "too small" to have a moon dazzles me. Pluto for example is a drawf planet. it is far away from the sun without a doubt but it has a moon 1/4 its size. it also has a bigger hill sphere which does make sense but the size of an object does not affect if it has a moon or not.
Venus can have a moon and keep it easily since the video already showed that its hill sphere was close to earth's in size the problem retrograde rotation or basicaly if the planet is rotating slower then the moon's orbital period it will stael that moon's kinetic energy and make the planet spin faster and venus is not just slow it rotates backwards so even if it had a moon its impossible for it to stay in orbit and no it wouldn't fly off into sun's orbit if it did we would find it anyway it would fall straight down into venus form a ring which will rain on the planet so its NOT the sun thats making venus moonless its its rotation but for mercury sun plays a bigger role in this and also rotation is very slow again so no moon
Nice
Jupiter,Saturn,Uranus,and Neptune had 95,146,28,and 16 moons
Imagine if mercury is Venus’s moon
Thanks a lot
You are welcome 🙂
That is WHY VENUS HAS NO LIFE BECAUSE IT HAS NO MOONS
Some people say that Mercury used me Venus's Moon.
Why are planets circle?
Hey buddy..!😀
how does neptune have a greater hill sphere than saturn and why is it a hill SPHERE
Saturn has 150 moons and Jupiter has 106 moons now
They are to close to the sun - sun ripped away anything that was about to orbit Mercury and Venus, and also not enough bodies came far enough to have one that made it to stay with them.
Venus had moon that crushes him
Then how do our satellites stay at mercury and venus? Wouldn't the same principles of Hill's Sphere apply?
Moons have greater mass than artificial satellites. Mass attracts mass, and more mass attracts more mass.
Plutos moons formed from Collision
Artificial satellites can maneuver to correct their course
It’s a shame that The Moon doesn’t have any moons.
Neith = Venus moon: Am i a joke to you?
I think axis isn't important... The gravity it is because moon still orbit a planet even its slow rotation... There's theory of Venus might have moon considered as mercury it got pulled towards the sun due to the immense gravitational pull... because of that the interaction of the gravity between mercury and venus it changed the axis of Venus...instead going to the right it rotate left🙆
Here a theory Mercury was once the moon of Venus billions of years ago but then the sun pulled mercury out of its orbit with Venus and mercury became its own planet
Mercury is Venus'moon and it always will be Venus' moon.
but isn't uranus's rotation completely vertical? why does uranus have many moons?
Uranus’s tilt is about 98 degrees on its axis, if we could see Uranus orbit around the sun it would look like a ball rolling on its side
Like the other gas giant planets Uranus had the gravitational force to grab up the remaining debris hence why they have so many moons compare to Earth and Mars
I am so immature
what about pluto
Imagine mercury and venus is moonless and mercury and venus have no moons :(
Jupiter and Saturn stole them, lol.
in irl there is moons of venus but those moons are called "possible moons"
I say four TUGGED but nobody wants to have that conversation..
I need my own moon 🥺
venus is really danguros
Fun fact of why they have no moons:because it’s just a 1 planet
Even pluto got a moon
If Venus has A Moon
It Would Be Menus or Voon
Venus esta atrayendo la luna hacia el.
Then how did Pluto get a moon
The binary dwarf planet system of Pluto and Charon was formed together from the rock, ice, nitrogen, and methane. The other moons are captured TNOs.
Venus in past already have moon but it got crash by asteroid and it moon get destroyed.
Didn't it crash into Venus Due to gravitational pull?
God knows how many moons orbiting Mercury and Venus have vanished into the sun.
Could Mercury have been a moon of Venus ?
But zoozve is venus mooni know
Did you know that mars moons are formed from a collision
Gravity of the Sun?
In actuality, Mercury is not a planet but the moon to Venus.
Maybe they’re moons and not planets 🤷🏽♀️🤔
2002VE Has Left The Chat.
Yes mercury looks like or moon soon its venus moon only 1 satellite
I have 83 moons
Hi
No moons? 🤨
No i have a moon
It's because Mercury and venus are the moon for the sun
Actually, Mercury is Venus' moon. All planets have moons just as all nucleii have electrons.
Because venus is too small to satellite moons it's had to be big enough to have moons
But mercury is small too of course they don't have moons
Mars is smaller than venus but it still has moons
Venus' size is similar to Earth's and Earth has a moon. Consider that Mercury is Venus' moon.
@@atomicplanets8226 mercury was larger before a collision and evidence suggests it actually came from beyond Mars until it got hit. Mercury's core is way too large for the planet. So no, it doesn't look like mercury was a moon.
Venus Has A Moon But Lost Because Venus Collided With An Object Forming A Moon Then Later Collided Another Object With Change Its Motion And Rotation. Then The Strong Gravity Of Venus Pulls Its Moon Into itself. Then That Moon Collided With Venus.
Our moon here sucks
Mercury and Venus are also a no moon
Mercury and Venus doesn’t had moon 🌙 because mercury and Venus are close to the sun 🌞 And mercury and Venus can’t hold they own moon 🌙
Because Mercury separated from Venus, Mercury is a moon that belonged to Venus. Mercury is not a planet in the moon.
And Ceres MakeMake doesn’t haves moons
Venus had a moon u know mercury but took by sun
Yaa you are right
Because drwaf palents like pluto makemake or vesta have moons even sedna have moons
So why not Murcury
Answer: thanks to sun🙃
Mercury and Venus please send a request to Sun to return u r Moons €€€€
I had a moon but collided with me 3.4 billion years ago
That was a planet not a moon
Distortion 😈
The sun
Mercury is a moon
There's a fact. Did you know Mercury used to be Venuses moon.
I did know that ;)
yeah, that's not true mr. OC kid.
@@ExiledNeptunium mercury is both sun and moon (androgynous)?
@@shylock5477 i don't know what you mean by that
@@ExiledNeptunium oh okay
I thought you knew what is true..
Mercury used to be a moon of Venus
Earth a 2 means but not one because the other another collision of the moon
You rhymed lol
Fun fact: Mercury is a rouge moon because it the moon of venus
Mercury was the moon of Venus when it was habitible.
i transform to a moon of venus my mom
Imagine kids and moms as planets and moons...the kids are the moons and the moms are the planets....kids basically orbit their moms
No mercury become moon of Venus but sun gravity is strong to get mercury that's why Venus doesn't have moon
Venus was not the rouge moon. Earth was not the rouge moon. Mars was not the rouge moon. Jupiter was the failed star. Saturn was not the rouge moon. Uranus was not the rouge moon. Neptune was not the rouge moon. Dun dun duuuun! Mercury was the rouge moon. Victory.
And Pluto is not a planet.
Mercury and Venus please send a request to Sun to return u r Moons €€€€
