Gravity can be described by the general theory of relativity by Albert Einstein in 1915 which describes gravity not as a force but as a consequence of the curvature of space-time caused by the uneven distribution of mass. Gravitation is a natural phenomenon by which all things with mass or energy including planets, stars and even galaxies are brought toward each other. On Earth gravity gives weight to physical objects.

Planets in our solar system circle around the sun. There are eight planets in our solar system. Smaller planets with solid ground include Mercury, Venus, Earth and Mars. There are four larger gas giants including Jupiter, Saturn, Uranus and Neptune. We are learning new things about our neighboring planets all the time. We send astronauts to space to take pictures, gather information and find out more about them. Their are eight planets inside of our own solar system and thousands of planets outside of our solar system.
