Let's take the sun as an example, since its hefty mass makes it a fun one. Knowing how much you'd weigh on the sun is just fun and silly. If you weigh 150 pounds 68 kg.
If you triple your separation, the force drops to one-ninth. Eris is 1,445 miles 2,326 km in diameter. In fact, as the ice melts, the atmosphere of the tiny body expands outward.
A dwarf planet:. All things by immortal power near or far to each other hiddenly linked are. Not only is the star very massive to start with about the same as the Sun , but it is also incredibly small about the size of San Francisco , so you are very close to the center and r is a very small number.
Before we get into the subject of gravity and how it acts, it's important to understand the difference between weight and mass.
Of course, the reason it can't clear out the Kuiper Belt it orbits through is because it lacks the gravitational force to do so, a fact related to its mass. Weight is the force gravity exerts on an object due to its mass. Your first email will arrive shortly. Did you find us useful? Neptune Diameter: In 2006, the International Astronomical Union came up with four criteria that cause an object to be classified as a dwarf planet.
If we put this into an equation it would look like this:.
Why It Happens. As stated above, your weight is a measure of the pull of gravity between you and the body you are standing on. Unlike many of the planets in the solar system, such as Earth, Pluto does not bulge at its center; its radius — 1,185 km 737 miles — is the same at its poles and at its equator. Take the most massive planet in the solar system, Jupiter, which tips the scales at 316 times the mass of the Earth.
This page should probably be titled Your weight on other heavenly bodies.
Note that the force never becomes zero no matter how far you travel. Mars' superior size, 1. It is less massive than seven of the moons in the solar system — Earth's moon, the four Galilean moons of Jupiter, Neptune's moon Triton, and Saturn's moon Titan.
