Pluto was the smallest planet in our solar system before it was reclassified (though Ceres is even smaller, and was considered a planet longer than Pluto). Because the gravity of an object is directly proportional to its mass and density, that would give Pluto the smallest surface gravity. It is now known that there are a few other large comets out there nearly as big as Pluto (Eris is even bigger). Pluto is no longer classified as a planet because it has not significantly cleared its orbit of debris.
Therefore of the eight planets in our solar system, Mercury is the smallest and has the least surface gravity. Mercury is also the most dense, having a large and rich iron core.

∙ 11y agoMars has the lowest surface gravity (0.376g), just a little lower than that of Mercury (0.38g). Although Mars is larger and more massive than Mercury, Mercury has a higher density, which effects the surface gravity.
Mars has a lower gravity at the surface than Mercury, but overall, Mercury has the lowest gravity when looking at the space further out from the surface, due to its low mass. The mass of a body is related to the gravitational field strength of the body.

F=mg where F is the force of gravity, m is the mass of an object, and g is the acceleration due to gravity. g is a constant for all masses of matter. Then the planet with the smallest mass would have the least Force of Gravity.

Planet with a force of gravity 2.54 times that of earth?
jupiter
What keeps the atmosphere around the earth?
A magnetic field holds atmosphere to the planet. Without a magnetosphere the solar wind from the sun will blow the atmosphere away. That is why our planet still has an atmosphere, we have the magnetic poles.
What planet has the weakest greenhouse effect?
Mercury
What force pulls the moon and earth toward each other?
gravity
What is the force behind mass movements?
gravity.
Which is the weakest force?
The weakest of the fundamental forces is gravity.
What is weakest gravity the strong force the weak force or the electromagnetic force?
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.
What planet has the smallest gravitional force?
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.
Which is the weakest fundamental force?
Force of gravity
It is the weakest but longest acting force?
Gravity
Is gravity the weakest universal force?
Yes.
Is gravity the second strongest force in the universe?
No gravity is the weakest force. The proper order is strong force, Electromagnetic, weak force, then gravity
Why is Pluto considered to have the weakest surface gravity?
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.
Is gravity the weakest force?
Yes Yes Yes
How does a planet gets its force of gravity?
The force of gravity of a planet is a product of its mass.
Why is gravity the weakest force in the universe?

What planet would you be the lightest on?
The surface gravity on Mars is the weakest, it is 37.6% of Earths.
