Distant planets

Handout picture released June 14, 2005 shows an artist's conception of a newly discovered planet being shown as a hot, rocky, geologically active world glowing in the deep red light of its nearby parent star, the M dwarf Gliese 876. The heat and the reddish light are among the few things about the new planet that are certain, depending on the thickness and composition of its atmosphere - if any - it could range from being a barren, cratered ball of rock like Mercury or the Moon, to being a featureless, cloud-shrouded cue-ball like Venus.
