-- Mercury
-- moon of Earth
-- moons of Mars
-- majority of moons of Jupiter and Saturn
Note:
While Mars technically has an atmosphere, its density is only around 1% of the density
of earth's atmosphere, so Mars is very close to joining the list.
What is Gravity?
The rocky or terrestrial planets have less atmosphere (but more breathable atmosphere) than the gas giants have, for two reasons. First, they are smaller, and therefore have weaker gravitational fields, which makes it easier for gas to leak away into space, and secondly, they are closer to the sun and therefore hotter, and the additional heat causes gas to expand, thus also contributing to its escape into space.
Well the wiki user said ”no” that is correct but the reason is partially correct as you can see the planet earth as an “atmosphere” that is the start where gravity starts pulling on the earth there is enough gravity on the earth than on the moon so no you will not be able to on the moon because the moon as a atmosphere it just doesn’t have enough gravity so no it will not work. if you do not understand let me know by putting a confused face than I will explain further and easier for you to understand.
Jupiter has the most gravity out of all the planets
Yes, gravity does stop gases from escaping from the planet. This layer of gases is called the atmosphere and it allows humans and plants to survive.

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.
For the same reason that our atmosphere on Earth does not escape into space - gravity.
For an object such as a planet or moon to have weather, it must have an atmosphere. Asteroids do not have strong enough gravity to maintain an atmosphere.
Mercury - the closest planet to the sun. Solar wind and radiation from the sun also blast off some of Mercury's minuscule atmosphere (Mercury's atmosphere is sometimes referred to as an exosphere)

Earth: Space: - is a planet - No gravity - supports life - Vaccum - gravity - No gravity or atmosphere - atmosphere
The mass of the planet. It's not clear cut, since there has to be gas around in the area to provide the atmosphere, but the planet (or moon) need to be massive enough to provide sufficient gravity for the gas molecules not to escape into space.
Where a planet or moon has an atmosphere, it is the gravity of the moon or planet that holds the atmosphere on the planet or moon.
