Mercury is the least massive of all the planets. The least massive planet is Mercury (0.055 Earths). However, the planet with the weakest gravity is Mars. I am of course not treating Pluto as a Planet (as it is no longer categorized as a planet), if I were to count Pluto then it would be the least massive ( 0.0021 Earths).
Io is a moon of Jupiter, not a planet. Surface gravity is about 18% of the gravity on Earth.
Gravity depends largely on mass, the bigger the planet the greater the gravity should be
because it's farthest from the sun.
Of course there is gravity in Australia. There is gravity everywhere on the planet.
Back when Pluto was still listed as a planet it was considered to have the weakest gravity of all the solar system's planets. Now that Pluto has been demoted from planetary status, the planet with the weakest surface gravity is Mercury. While Pluto's gravity is weaker than that of any planet in the solar system, there are still many non-plantery objects with weaker surface gravity.
The surface gravity on Mars is the weakest, it is 37.6% of Earths.
No. The gravitational pull at the surface of a planet depends on that planet's mass and radius. Jupiter has the strongest gravity of any planet in the solar system: 2.53 times the surface gravity on Earth. Mercury has the weakest surface gravity at just 37% the gravity on Earth.
Believe it or not Mars has the weakest gravity of the planets.Mars = 0.376gMercury = 0.38gEven though Mercury is the smallest planet, it is very dense.
The weakest of the fundamental forces is gravity.
No. Pluto has weaker gravity than any of the planets, which would have meant it had the weakest gravity when it was still considered a planet. Other, non-planetary bodies such as asteroid and comets have far weaker gravity.
It doesn't. Mercury, Venus, Mars, and Pluto have less gravitational acceleration at their surface than Earth has. That leaves only Jupiter, Saturn, Uranus, and Neptune with stronger gravity.
Far from a small mass.
Yes.

Gravity is the weakest force. In order from strongest to weakest is the strong force, the electromagnetic force, the weak force, and gravity. However, this is relative to distance - one could consider that gravity is the strongest force because its effect can be felt over enormous distances, even astronomical distances.
