​

​VENUS: Venus is known for it's toxic atmosphere, greenhouse gases and being the most hostile and hottest planet in the solar system. The sister of Earth is believed to have had life in the early days of the solar system.

​

​EARTH: Next up is home planet Earth. It is known as the only planet with life (CURRENTLY ). It is also the only planet known which flourishes in poison. ( Oxygen is a toxic gas with horrible high reactive properties.)

MARS: Commonly known as the red planet, Mars is red because of the high Iron content exposer to water over many years. Many scientists and astronomers believe that Mars had life in the past. In 2006, astronomers found a mar meteorite which contained fossilized waste left there by bacteria.
