It blocks out the harmful rays of the sun.
The three essential criteria for making a planet habitable are the presence of liquid water, a stable atmosphere, and a suitable temperature range for life to exist.
No, there would have to be an atmosphere and water as well.
Scientists look for certain conditions when determining if a planet is habitable. This includes the presence of liquid water, a suitable atmosphere, a stable climate, and the right distance from its star to maintain a temperature hospitable to life. Observations from telescopes, spacecraft, and simulations help in assessing a planet's potential habitability.
The Earth is habitable due to a combination of factors, including its distance from the sun, presence of liquid water, protective atmosphere, and stable climate. These factors allow for the existence of life as we know it.
As of (2011) no planets have been observed that are habitable. Some MIGHT be, but until detailed research is done on the actual conditions, it cannot be said a planet is habitable.
Earth is the planet that has water, oxygen, and regulated temperatures that can support life as we know it. Its atmosphere and location within the habitable zone allow for these conditions to exist.
earth..The most habitable planet in the Solar System is Earth. As of June 2014, Earth is the only planet that has sustained known living things.
It can vary substantially. Whether a planet is a Goldilocks planet is based only on its distance from the star it orbits. If a planet orbits at the right distance that it might be the right temperature to support liquid water, it is called a Goldilocks planet. The nature of the atmosphere would still be affected by factors such as the planet's composition, mass, and evolutionary history.
Terraform it.
The mass of the planet. It's not clear cut, since there has to be gas around in the area to provide the atmosphere, but the planet (or moon) need to be massive enough to provide sufficient gravity for the gas molecules not to escape into space.
No. Many planets have atmospheres, but most are made of noxious gases, have to great an amount of pressure, or are to cold or hot to be habitable for humans.
