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 relatively cool red dwarf 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).
