Spitzer Finds Possible Exoplanet Smaller Than Earth

Astronomers believe is an alien world just two-Thirds the size of Earth - one of the Smallest on record. It was Identified by NASA's Spitzer Space Telescope. The exoplanet candidate, Known as UCF-1.01, orbits a star Called GJ 436, Which is located a mere 33 light-years away. Might be UCF-1.01 to the nearest world That is our solar system than our home planet Smaller.

The exoplanet "closest" to the Earth

The Kepler space mission has exposed the exoplanet, closet to the Earthlike identified so far. Dub Kepler 10b, the planet is unstable (solid) smaller than those found, since the diameter is the same to just 1.4 times the Earth, while its mass is 4.6 times that of Earth.

In attendance can be no illusions, however, about the possibility of life existing in it, because although Kepler 10b orbits a star (Kepler 10) very similar to our Sun, its distance to it is twenty times less than separating the sun Mercury.
