Even though all planets are part of the solar system and revolve around the sun,they look different.  Why is it so? Because their composition varies.

Mercury is a small rocky world.  It has a very thin atmosphere of carbon dioxide.  Venus is a white globe completely covered by a larger of white clouds,which are made up of  concentrated sulphuric acid.  The atmosphere is hot and made largely of unbreathable carbon dioxide gas.  Mars is a red planet with an atmosphere of carbon dioxide in which clouds form.  Jupiter appears as a yellowish globe with colourful bands of clouds swirling around it.
