Characteristics to Support Life on Earth

Scientists have determined that there is a particular distance from the Sun that is most likely to allow life to inhabit a planet. This area is called the inhabitable zone and is shaded in the diagram below. Also, the planet needs liquid water and oxygen present. According to the information above, why would Planet E NOT be a good place to look for life?

• Too hot

• No oxygen

• Too cold

• No water
