New Planet Points the Way for ET Hunters In a solar system far, far away, around a small and dim star, orbits a small planet, just three times the size of Earth.
The astronomers who discovered the small planet don’t know much else about it yet, but the basics are enough to get them excited. Extraterrestrial life is thought to have the best chance of surviving on planets with a similar mass to that of Earth, orbiting small stars. This planet, which goes by the romantic name MOA-2007-BLG-192Lb, is the second smallest planet ever spotted outside our solar system.
