On Thursday, Aug. 26, 2010, NASA announced the discovery of a planetary system that has been confirmed to have at least two Saturn-sized planets and – just possibly – the smallest alien planet yet seen – a candidate world that would be about 1.5 times the radius of our own Earth.
It is the second possible Earth-sized planet to be announced this week. What do you think? Cast your vote on whether true Earth-like planets the size of our world or smaller will be found around alien stars in orbits that allow them to be habitable.
