What planet doesn't have gravity?
venus. This is not a good answer. As it turns out Venus must assuredly has an atmosphere, though not at all like ours as it consists mostly of carbon dioxide and has an overall pressure at the surface 90 times that of Earth or roughly that of what a submarine encounters 1/2 mile below the surface. The answer turns out to be more complicated than the question: it is a combination of a number of factors which determines whether a planet has an atmosphere. Mercury is both hot and light, and in close proximity to the sun's atmosphere stripping solar winds. These three factors contribute to an almost non-existent atmosphere. Even lowly Pluto, now demoted to a so-called trans-neptunian object, has more of an atmosphere than does Mercury.
Why does the atmosphere not just float away. Surely gravity isn't strong enough since it doesn't even stop steam rising?
The atmosphere is held in place by Earth's gravity, which is strong enough to keep it from floating away into space. The molecules in steam are moving faster than air molecules in the atmosphere, so they can rise against gravity. The atmosphere is trapped by Earth's gravitational pull, preventing it from escaping like steam.
Why does Air stay within the Atmosphere - solid and liquid are pulled by gravity BUT i don't agree Air is pulled by gravity?
First of all, the atmosphere is the air. Secondly, air is matter, all matter is affected by gravity. Imagine this: the sea is liquid, it lies on the earth, pulled by gravity. the atmosphere is also like this except it is a "sea" of air, it lies on the earth, pulled by gravity.
Is gravity oxygen?
No, gravity is not oxygen. Gravity is the force that pulls objects toward each other, while oxygen is a chemical element that is essential for life and makes up a large portion of the Earth's atmosphere.
Why do we need gravity for life on Earth?
Gravity is essential for life on Earth because it keeps our atmosphere in place, allows water to flow, and enables plants to grow towards the sun. Without gravity, our planet would not be able to support life as we know it.
What holds the Earth's atmosphere in place?
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.
Why doesn't weather occur on asteroids?
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.
This holds a planet's atmosphere close to its surface?
Gravity holds a planet's atmosphere close to its surface. The gravitational force of the planet's mass prevents the gases in the atmosphere from escaping into space. Without gravity, the atmosphere would disperse into space.
Mercury does not have enough gravity to hold this?
ya it has a little bit less gravity than the moon. its........floaty..........
What planet doesn't have enough gravity to have 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)

What force holds a planet's atmosphere in place?
Gravity holds the atmosphere around the planet. Gravity is the force that attracts a body toward the center of the planet. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
Explain how earth's mass is related to its ability to have an atmosphere?
The Earth has an atmosphere because it has the gravity necessary to keep the gases from floating off into space. The more mass a planet has, the more gravity it has, and the more gravity it has, the thicker an atmosphere it can sustain.
What property of a planet determines if the planet can have an 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.
Why is space not like earth?
Earth: Space: - is a planet - No gravity - supports life - Vaccum - gravity - No gravity or atmosphere - atmosphere
Which planet has enough gravity to hold on to most gases?
Jupiter has enough gravity to hold on to most gases because it is the largest planet in our solar system. Its strong gravitational pull prevents gases from escaping into space, allowing it to maintain its thick atmosphere.
