 There's something missing here…This page is missing critical information of some kind. It might need a location, or names of people involved, or something else. It might be outdated. It might be a Wikipedia or SolStation data dump with little or no relation – or, worse yet, with contradictions – to the situation in Fenspace. It might have inconsistencies. It might even be missing multiple details. You can help FenWiki by expanding this page. |

BD -21°5081 is located about 42.3 light-years from Sol. This southern star lies in the western part of the constellation Sagittarius, the Archer. BD -21°5081 is a yellow-orange main sequence dwarf star of spectral and luminosity type G5 V. The star may have a mass similar to that of Sol, 93 percent of its diameter[1], and 65 percent of its luminosity.
For an Earth-type planet around BD -21°5081 to have liquid water at its surface, it would need a stable orbit centered around 0.81 AU -- between the orbital distances of Venus and Earth in the Solar System. Such a planet would have an orbital period less than one Earth year.
