What planet doesn't have gravity?

Answer 1

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.

Answer 2

There is no planet with no gravity. Anything with mass (including you) has gravity (although you have a very, very small amount of gravity compared to a planet).

(However, if you were inside an evenly distributed hollow sphere, the gravity at all points would cancel out, and there would be in effect no gravity. No known such planet exists, though.)

Answer 3

Every observation up to the present time indicates pretty conclusively that

gravity exists everywhere, at least in the part of the universe that we can see.

So there are no planets without gravity.

Also, notice that if there were a planet that was immune to the force of gravity

for some reason, then it couldn't be in orbit around anything, because it's the

force of gravity that keeps a planet in an orbit.

Oh, we just thought of another interesting detail: If the material in the planet

was immune to the force of gravity for some reason, then there would be nothing

holding the planet together, and there would be no planet. Just some kind of

a bunch of stuff that would dissipate like a cloud of lazy smoke.

Answer 4

Every planet has gravity because every planet has mass.

Answer 5

The planet Mercury has no atmosphere due to weak gravity. It also has no atmosphere because of the harsh solar winds it gets from being so close to the sun.

Answer 6

The planet Mercury, and every moon except for Titan and Triton.

Answer 7

None. All planets have noticeable gravity.

Answer 8

No such planet. Every particle and speck of mass in the universe is gravitationally

attracted to every other particle or speck of mass in the universe.

Answer 9

There is no planet that don't have gravity.
