| Summary: | Star GJ 1214 and it's exoplanet. |
| Description: | GJ 1214 (Gliese-Jahreiss 1214) is a dim M4.5 red dwarf in the constellation Ophiuchus with an apparent magnitude of 14.7. It is located at a distance of approximately 40 light years from Earth. It is about one-fifth as large as the Sun with a surface temperature estimated to be 4,900 °F (2700 °C). Its brightness is only 0.3% that of the Sun. The estimate for the stellar radius is 15% larger than predicted by theoretical models. In mid-December 2009, a team of Harvard-Smithsonian astronomers announced the discovery of a companion extrasolar planet, GJ 1214 b, potentially composed largely of water and having the mass and diameter of a Super-Earth. |

Isn't this system already implemented in the default Celestia?

...but let's not knock the guy for trying. I am happy to use this add on.

Well, I'd like to point out that a more complete add-on for GJ 12141 system is already available here, though named as MEarth-1. With its own texture rather a general one.
