The Planets [Key Words] [General] [Basic Planetary Data] 
General
There are nine planets in our Solar System, and each is very unique. If you visited each planet, your weight would be different because weight is a measure of the force of gravity on objects. So, if you want to weigh less, head to Mars. If you want to weigh more, go for Jupiter. To find out more about your weight on each planet, just weigh yourself. Each planet is very interesting and it is a good idea to compare them. Look at the data table below for more general information on all the planets. To find out specifics about each planet, use the links above (click on the words or the planet itself).
