PLANETS ARE IN ORBIT

• Webster’s dictionary states “that a path describes by one body in its revolution about another (as by the earth about the sun or by an electron about an atomic nucleus); one complete revolution of a body describing such a path. ”

• This is why we have 365 days in a year, because that is how long it take us to travel around the sun!

• Revolution: a revolution of a planet is how long the planet takes to orbit the sun.

• Rotation: is how long it takes for the planet it’s self to make one full circle. • Picture Retrieved from: https://www.google.com/search?
