The gas giants Jupiter, Saturn, Uranus, and Neptune are all mainly composed of gas the only solid being the core which is rock, and metallic, The gas giants are all 95% or greater made of hydrogen which is a very light gas, what keeps all these giant gas planets together is that Jupiter is 318 times as massive as Earth Saturn is about 95 and Uranus and Neptune are about 20 times as massive as Earth, Meaning that the gravity pull of the gas giants is much greater than Earths and is what keeps all these gases together.
Comment: Yes. Also the fact that the planets are so far from the Sun helps stop
gas molecules etc., reaching "escape velocity".
A "hot Jupiter" would be losing matter, we think.
Two things:
1. In space, there is nothing to 'float' in.
2. There is a tremedous total force of gravity holding all the planets in their orbits around the sun. It's like if you were to tie a string to a small ball, then swing the ball around and around you. The ball is like the planet, and the string is like gravity, keeping the ball from shooting out away from you.
I am not 100% sure but everything that has mass, has gravity, so I would venture to guess that the gravity of the massive planet holds it together.
The gas planets have rings because of the gravitational pull and the outward force of the gases causing any meteors to be trapped in the ring.
so the scientists said that all the planets should have gas just remember
Jupiter hold all the gasses in its atmosphere by gravitational attraction, just the way the other planets do.
Gravity is what causes ALL large celestial bodies to collapse into a sphere.
Because it just does.
it would just float away that's why astronauts have to hold on to there food in space but it would be cool to just see your food float away
The Planets can just keep building up over a period of time and just keep collecting stuff.
a sucktional tube to make sure it deosnt just float away
the further away from the sun it is the colder it gets
Because it just does.
because it just does ok!

Ultimately, no. If you try, the beer will just float away
The Planets can just keep building up over a period of time and just keep collecting stuff.
then all of the planets will just fly away in space they will just keep on flying.

Prokaryotes doesnt have a membrane its organelles pretty much just float around unlike eukaryotes it contains a membrane where the organelles are kept proteinsynthesis in prokaryotes- it doesnt not contain "noncoding" meaning it doesnt have introns
Our nine planets orbit around the Sun. Other planets that are light-years away orbit around their suns (A sun is just a large star with planets). Hope this helped!
Just like Earth's gravity holds you to Earth, and doesn't let you float away, Mars, too, has some gravity (less than Earth), which won't simply let objects float away into space.
There is no gravity in space so they just sort of float and every planet orbits around the sun and also helps them stay in place
gravity is the force that keeps objects on the earth, if we didn't have gravity we would just float away
