Every object in the universe with mass attracts every other object with mass. The amount of attraction depends on the mass of those objects and how far apart they are. For everyday-sized objects, this gravitational pull is very small small, but the pull between a very large objects, like the Earth, and another object, like you, can be easily measured. How? All you have to do is stand on a scale! Scales measure the force of attraction between you and the Earth. This force of attraction between you and the Earth (or any other planet) is called your weight.
This application allows you to calculate how much you weigh on other planets and suns. A fun and educational application and an aid to teaching young children.
