Scaling the Solar System

a.)
Earth- 3 ft.
Mars- 5 ft.

I believe this because scientists have a very good estimate on the scale of the universe. This means that if we were to change the diameter of the Sun, we would be able to have a good estimate on how far away other planets are.

b.) 5.68 years old

The farther away a planet is from the sun, the longer it takes for the planet to make one complete revolution. This means it takes longer for a year to happen on different planets, depending on how far away they are from the sun. So we would be different ages on different planets.

c.) Mars- 75.4
Jupitar would make me the heaviest

Your weight is a measure of the pull of gravity between you and the body you're standing on. The force of gravity depends on your mass and the mass of the planet you're on. So, since Mars, Earth, and Jupitar have different masses, the weights will be different.
