Top 5 Most Habitable Alien Planets

By | On + -

600 light years away

  Kepler-22b was spotted by NASA’s planet-hunting Kepler space telescope, which has detected more than 2,300 potential exoplanets since its March 2009 launch. Only a small number have been confirmed so far, but the vast majority should end up being the real deal, researchers have said.

Kepler-22b’s star is located about 600 light-years away in the Cygnus constellation. The planet has a year of 290 days and is about 2.4 times the size of Earth. Astronomers predict that this world is almost entirely covered in water with a rocky core. The possibility of habitability all depends on the level of greenhouse gasses, which could make the planet more like Venus than Earth. More information about the planet:

    I am doing a project for school and your web sight says that this planet gliese is 1750 light years away from earth but at the bottom of the web sight is a link to read more on the planet and if you click that the info on that page says it is only about 20 light years away, that is a really big difference! so which is it, 1750 or 20?
