What does a planet need to support life?

Answer 1

It would need a source of food and water. It would also need a form of shelter from whatever weather the planet might have.

In addition to food and water, life needs oxygen in a form it can use, enough pressure to keep the life from blowing apart and from its liquids boiling away without being enough to crush it, an environmental temperature that is not cold enough or hot enough to kill the life, and protection from harmful solar radiation.

Answer 2

For a planet to support life, it typically needs liquid water, an atmosphere that provides protection and regulates temperature, organic molecules for the formation of life, and a stable source of energy like sunlight. Additionally, the planet should be within a habitable zone around its star to maintain appropriate temperatures for life to exist.

Answer 3

If there is water or ice on the planet it could support life.

Answer 4

Water Oxygen The right gravitational pull Right temperature

Answer 5

Whether the planet has water on it and whether the conditions are liveable for that species.

Answer 6

It also needs an atmosphere.

Answer 7

As far as we know, Earth is the only planet to contain life. However, it is possible that some form of life could exist on Venus or Mars, or even on one of the icy moons of Jupiter.
