Are there any other planets that can support life?

Planetary habitability

• Understanding planetary habitability is partly an extrapolation of the conditions on Earth, as this is the only planet known to support life.
• The moons of some gas giants could potentially be habitable.

What is the closest planet to Earth that could support life?

An international team of astronomers has found signs that a habitable planet may be lurking in Alpha Centauri, a binary star system a mere 4.37 light-years away. It could be one of the closest habitable planet prospects to date, although it’s probably not much like Earth if it exists.

Can you breathe on Mars?

The atmosphere on Mars is mostly made of carbon dioxide. It is also 100 times thinner than Earth’s atmosphere, so even if it did have a similar composition to the air here, humans would be unable to breathe it to survive.

Is there life on Venus?

Although there is little possibility of existing life near the surface of Venus, the altitudes about 50 km (31 mi) above the surface have a mild temperature, and hence there are still some opinions in favor of such a possibility in the atmosphere of Venus.

What is the closest planet to support life?

A newly discovered Earth-sized world could be the closest planet capable of supporting life, scientists believe. The planet, named Ross 128b, and despite being 11 light-years away it is moving towards our solar system.

How many planets exist that can support life?

It turns out that in the Milky Way, scientists now believe that there are 60 billion planets in the habitable zone. The habitable zone is located where a planet is warm enough to keep water on the surface in liquid form without it turning into gas [source: Gannon ].

What planets could sustain life?

Planet Earth. In addition to being the birthplace of humanity and the cradle of human civilization, Earth is the only known planet in our Solar System that is capable of sustaining life. As a terrestrial planet, Earth is located within the Inner Solar System between between Venus and Mars (which are also terrestrial planets).

Which planets cannot support life?

It seems unlikely that Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are unable to support life. Venus and half of Mercury are to hot.
