Your Weight in Space
Did you know that your weight on other planets and moons would be different than your weight on Earth? Why? Gravity is a force that pulls you toward the center of the planet or moon. When you step on a scale on Earth, you see how much Earth’s gravity is pulling your body toward its center. Gravity is not the same on other planets or moons, so you would not weigh the same on other planets as you do on Earth.
Count Your Age in Space
A year is the time it takes a planet to go around the sun one time. Your age is how many Earth years you have lived. Years are not the same on other planets or moons. If you use another planet’s year, your age would not be the same there as it is on Earth.
