All of the planets have. Sadly though, Earth is
the only one with any grass to hold on to.
Jupiter has the most gravity out of all the planets
I think it is Venus or Earth.
Sure does.
ya it has a little bit less gravity than the moon. its........floaty..........
The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere. The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.
Earth & Venus.

The gravity of a planet does not hold it in place, nor does any planet stay still. The planets are in constant motion as they orbit the sun.
The atmosphere is held in place by the earth's gravity. Gravity is related to mass, the more mass a planet has, the more gravity. A much smaller planet like mercury or a body such as the moon will have less gravity, not enough to hold an atmosphere - the gravity is not strong enough to prevent the gas particles from escaping into space.
Jupiter
Simple observation proves (and has always proven) that Pluto is not a gaseous planet. Just knowing Pluto's diameter is proof: No gaseous planet can be that small because there wouldn't be enough gravity to hold the gas into a ball shape.
Sure does.
Depends on how much smaller my planet was. If my Earth were too small to create enough gravity to hold an atmosphere or an ocean, I would not be here -- indeed, no life would be here -- to get upset over too small a planet. I'm sure it's the same situation on your planet.
gravity and temperature; It needs gravity so it can hold its atmosphere.
The moon has gravity, but it is much weaker than the gravity on Earth. It is not enough to hold onto an atmosphere.
the bigger the planet the more gravity it has because it needs to hold it self together so it has more gravity than smaller planets who require a small amount of gravity to hold themselves toghther
