A person would weigh the least on Pluto, the most remote of the planets in the solar system (until recently). But Pluto, it seems, has been demoted from a planet to a dwarf planet. That makes Mercury, our solar neighbor that is closest to the sun, the planet on which one would weigh the least. The weight of a person varies as a function of the mass of the planet on which one is weighed, and Mercury is the smallest and least massive of the planets now that Pluto has been sent into relegation.
Solar systems do not create the weight felt. The mass of the body you are standing on creats weight. The proper question would be what planet would you weigh the least? In our solar system the answer would possibly be mercury as it is the smallest however it is mostly iron which is dense so gravity would have a stronger affect.
A:Pluto, currently classified as a dwarf planet, would have less gravity than Mercury.Various moons, of course, would have a lower gravitational pull than the planets, although many are actually larger and more massive than Pluto. So, for example, our moon would have more gravity than Pluto.
Jupiter, however, has 63 moons, the smallest is barely 1 km in diameter designated S/2003 J12. However, smaller asteroids would would have even less gravitational pull.
When an object is in freefall, there really is no definition of weight. I.E. one is weightless. A stable orbit is a special case of freefall where one is always moving away from the planet and falling towards it... and again is weightless. So, since the international space station is in orbit, one would be weightless while inside.
Likewise, when on a moon, there would be little effect of the planet it is orbiting.
The Lagrangian points are at a somewhat unique place where all gravitational forces cancel out, and where one would also be weightless, but would not be moving, falling, or accelerating with respect to the system.
Your weight depends on the force of gravity on the planets surface, which varies depending on various factors relating to the planets size and mass.
With the force of gravity on the Earths surface as 1 g, all eight planets are as follows;
Mars = 0.376g
Mercury = 0.38g
Uranus = 0.886g
Venus = 0.904g
Earth = 1g
Neptune = 1.14g
Jupiter = 2.528g
..so to calculate your weight on Mercury, take your mass and multiply by 0.376.
Your weight is a function of the gravitational attraction of an object on your mass, so on which planet (excluding Pluto) would you weigh the least?
Mercury or Mars.
Mercury or Mars.
Pluto

you would weigh the least on mars. (take in account Pluto is not a planet any more)
Venus
Mars is a smaller planet than Earth. Your weight is the product of two masses yours and the planets Your mass stays the same wherever you are, if you stand on a smaller planet, you weigh less.
The acceleration of gravity on the surface of Pluto is 0.583 m/s2 . That's 5.94 percent of its value on Earth. If you weigh 200 pounds on Earth, you would weigh 11pounds 14.2ounces on Pluto.

Since Pluto's gravitational pull on its surface is only about 6% that of the Earth on its surface, you would weigh 6% of your Earth weight if you were to stand on Pluto's surface. So, to convert your Earth-weight to your Pluto-weight, you have to multiply your Earth weight by 0.06. In this case, if you weigh 125 lbs on the Earth, you would weigh 7.43 lbs on Pluto.

There is no minimum weight requirement to go to Pluto (which, incidentally is no longer considered a true planet). However, the current burden on our level of technology is such that, the value of sending an astronaut to Pluto would not outweigh the difficulty and expense. In July 2015 the NASA New Horizons probe is expected to do a flyby of Pluto and capture the first close photographs; its mass is about 470kg. If a man weighing 72kg (about 160lb) stood on the surface of Pluto, he would there weigh about 5 kg (about 11lb)
The mass of dwarf planet Pluto is about 1.3 x 1022 kg, or about 2.87 x 1022 pounds. However, we don't normally talk about how much a planet weighs - we talk about how much mass the planet has. Mass and weight are two different things.
Venus
You weigh more on Earth than on Pluto because Earth has a higher gravitational pull than Pluto does.
Pluto has 8% of the gravity of earth so if you weigh 100 pounds here you will weigh 8 pounds on Pluto.
If you still consider Pluto a planet as I do, that would be the place for you to work out. Being the farthest from the sun causes it to have little gravity. It's just 7 percent of our gravity, if you weighed 100 kg on Earth you would weigh 7 kg on Pluto.
