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.
why does Pluto have the weakest surface gravitu
Of the solar system it is, but its not considered to have the weakest, it does have the weakest. And that is because it has the least amount of mass.
The "surface" gravity of Jupiter is about 40 times that of Pluto.
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.
The force of gravity at Pluto's surface on an object with a mass of 100kg is approximately 58N .
0.067 times Earth's gravity, or 0.658 m/s2.
No. Pluto has gravity. It is considered a dwarf planet because it is unable to clear its orbital path of debris.
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.
because it's farthest from the sun.
The "surface" gravity of Jupiter is about 40 times that of Pluto.

gravity on Pluto is about 1/12th the surface gravity on Earth
Yes. Pluto's surface gravity is about 6.7% that of Earth.
The force of gravity at Pluto's surface on an object with a mass of 100kg is approximately 58N .
The surface gravity on Pluto would be 0.58 meters/second2, or about 1/17th that of earth's.
There isn't. The "surface gravity" is dependent on the mass (of the planet, etc.) and the distance of the surface from the center of mass. Pluto has MUCH LESS mass than Earth and the gravity is much less on Pluto.
There are forces of gravity between every speck of mass in the universe and every other speck of mass, no matter where they are, how far apart, or how large or small, all the time, everywhere, right now.
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.
Pluto has a weaker surface gravity than a planet because it has much less mass than a planet has.
