Earth is currently 150 million km away from the Sun. If Earth was 200 million km away from the Sun, it would no longer support life because -

• the surface water would evaporate.

• the temperature would be too cold.

• the oxygen would leave the atmosphere.

• there would be less exposure to solar wind.
