OGLE-2005-BLG-390Lb

January 26, 2006

Using an armada of telescopes, an international team of astronomers has found the smallest planet ever detected around a normal star outside our solar system.

The extrasolar planet is five times as massive as Earth and orbits a red dwarf, a relatively cool star, every 10 years.

This artist's illustration shows an icy/rocky planet orbiting a dim 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).
