Ever wondered how much you weigh on the different planets?I weigh 303.3 lbs. on Jupiter and 8 lbs. on Pluto. I even tested my cousin, he weighs 76 lbs. on earth but on the Moon he weighs 12.6 lbs. Mass does not change when we change planets. However, if we went to Mars, our weight would change because Mars has less gravity than Earth. Gravity is a force that pulls matter together.

How old are you on the other planets?
I am currently 12 years of age. However on Mercury I am 50 years old, 19 years old on Venus and 6 years old on Mars. The rotation of the earth on its axis is how we define the day. It takes Earth exactly 24 hrs. to spin around it's axis. It takes Venus 243 days to spin once that's why my age differs on the others planets.
