One more place to hang out

Scientists have discovered a planet more like Earth than any other found before. This groundbreaking discovery of planet takes the nondescript name "OGLE-2005-BLG-390" after one such telescope, named OGLE, for Optical Gravitational Lensing Experiment.

It's 20,000 light-years away, just shy of the center of the Milky Way. The planet is five times the mass of Earth, but it's still considered the smallest and coolest ever detected outside of the solar system, according to the scientists.

Scientists also predict it has a thin atmosphere, like Earth, with a rocky surface buried deep under frozen oceans. These characteristics would make it a larger version of Pluto, rather than the rocky inner solar planets like Earth and Venus.
