`Iceball` planet discovered through microlensing
(PHYSorg.com Space & Earth)

Scientists have discovered a new planet with the mass of Earth, orbiting its star at the same distance that we orbit our sun. The planet is likely far too cold to be habitable for life as we know it, however, because its star is so faint. But the discovery adds to scientists` understanding of the types of planetary systems that exist beyond our own.
