As of 24 April 2007 227 extrasolar planets have been discovered.
The distance to Gliese 581 C is given as 20.5 light years.
20.5 light years or at space shuttle speeds, 800,000 years.
The star is Gliese 581, and this is the second planet definitely found around it, with a third suspected. There are now 225 known or suspected extra-solar planets.
Gliese 581 is 20.4 lightyears away according to the Hipparcos catalog, and is located in Libra. It is an M2.5V red dwarf.
Wilhelm Gliese died several years ago at the age of 78. He worked out of an observatory associated with Heidelburg.
