A habitable planet for Epsilon Eridani
May. 16th, 2011 08:28 pmHere is a link to some basic data on this orange star. As it seems to have a luminosity of 0.29, its life zone ranges from 0.38 AU on the inside to 0.81 on the outside. Earth twin distance comes out to 0.54. An Earth twin’s “year” would be around 45 Earth days long. Note that Epsilon Eridani may have some giant planets that lie far beyond the life zone – the jury of astronomers is still out on their actual existence.
