Is It Realistic That People Can Live on Another Planet?

There are nine planets in the solar system. Why should only one of them be able to support life? This is one question that a lot of people have failed to get answer to. There has been a lot of research to determine if life can be supported on other planets but none have concrete information. There are a lot of things that we as human need in order to survive in a planet. Any planet that will host humans need oxygen, water, and a suitable temperature. Let us consider some of the other planets in the solar system to know whether people can survive there.

  • Mercury: First on the list is mercury. This is the closest planet to the sun. As a result, it is obvious that the temperature will be extreme. Although the planet is made up of about 52% oxygen, this amount is not enough. Mercury is also usually hit by meteors which mean frequent natural disaster for the inhabitants. All these qualities about mercury makes it impossible for you to survive there.
  • Venus: This particular planet has a fairly constant temperature. It has a thick atmosphere that traps heat and hence makes the planet hot with a temperature of about 464o This temperature is certainly too hot for humans. Venus also has a lot of volcanic activities on it, thus making life on the planet unbearable.
  • Mars: This planet is the best bet if life is possible on another planet. It has a low temperature that ranges between -125 to 27 degrees Celsius that is quite bearable for you. There is currently no water there. However, there is evidence that water once flowed on the planet. Ice is also present on the planet. Therefore, mars is inhabitable due to the non-existence of water.
  • Jupiter: The gravity here is twice what is experienced on earth. It has a very cold temperature of about -110 degrees Celsius that is too cold for you. Both water and oxygen are absent on this planet which are both essential for your survival.
  • Saturn: It has almost the same gravity with earth. Just like Jupiter, Saturn does not have any solid part except its core which is mainly composed of gas. There is no oxygen here, and the temperature is extremely low for humans. Saturn is totally unfit for the survival of humans.
  • Uranus: Uranus is made up of water, methane, hydrogen and helium gas with no oxygen. The temperature of Uranus is extreme being as low as -214 degrees Celsius. Its atmosphere absorbs the sunlight which further reduces the temperature of the planet. The extremely low temperature completely rules out the survival of people on Uranus.
  • Neptune: This planet is very similar to Uranus. It lacks oxygen and also has more gravity than what is experienced on earth. The high gravity means that its temperature varies rapidly. It is farther from the sun than Uranus which makes Neptune even colder. It is impossible for you to survive for a second on Neptune.


No planet in our solar system will be suitable to support mankind. They are usually either too hot or cold, lack water or oxygen. Some also do not have a solid ground that can support life.
