Planets

Gravity is a FORCE that tries to pull two objects closer. Any object with mass has a gravitational force and the bigger the mass of an object, the stronger that gravitational pull will be. Gravity holds the planets around the Sun and keeps them in constant ORBIT. The closer you are to an object, the stronger the gravitational pull will be.

Planets

First Four planets (Mercury, Venus, Earth, Mars) are called TERESTRIAL because they have a solid rock surface. Last Four Planets (Jupiter, Saturn, Uranus, Neptune) are called GAS GIANTS because they are composed up of dense layers of gas. They are labeled Giants because they are the largest planets in our Solar System.
