The Gravitational Force at work in our Solar System

Take a look at this photo of the Solar System to help  better educate yourself over the following information!
Look at the different sizes, colors, features, and distance of each planet:



The orbit of the planets in our Solar System determines the length of the year, and when the seasons change. Relative to the sun, earth moves 70,000 miles per hour (FAST)! The sun supplies centripetal force to the earth. This makes the earth travel in a circle.

Why do planets orbit the sun?
Planets orbit the sun because of the gravitational attraction between each planet and the sun.

Each planet exerts gravitational force on every object in the Solar System, as a result, planets having moving objects that rotate around them. For example, the moon orbits the earth. Did you know that Jupiter has not just one, but 60 satellites! The four biggest satellites were discovered by Galileo, thus getting the name "Galilean Satellites".

Saturn, Uranus, Jupiter, Neptune have planetry rings.
