Kepler-22b: Earth-like planet confirmed
Advertisements [?]
Source: BBC

The planet, Kepler 22-b, lies about 600 light-years away and is about 2.4 times the size of Earth, and has a temperature of about 22C.

It is the closest confirmed planet yet to one like ours - an "Earth 2.0".

However, the team does not yet know if Kepler 22-b is made mostly of rock, gas or liquid.


Kepler 22-b lies at a distance from its sun about 15% less than the distance from the Earth to the Sun, and its year takes about 290 days. However, its sun puts out about 25% less light, keeping the planet at its balmy temperature that would support the existence of liquid water.

Cooool. :)
