Artist's Concept of Exoplanet OGLE-2005-BLG-390Lb

January 30, 2006
This artist's illustration shows an icy/rocky planet orbiting a dim star. Astronomers detected an extrasolar planet five times as massive as Earth circling a red dwarf, a relatively cool star. The distance between the planet, designated OGLE-2005-BLG-390Lb, and its host is about three times greater than that between the Earth and the Sun. The planet's large orbit and its dim parent star make its likely surface temperature a frigid minus 364 degrees Fahrenheit (minus 220 degrees Celsius).
