NASAs TESS satellite will be looking toward that star later this year, and if the planet transits, we could get more information about its density or atmosphere. Epsilon Eridani is classified as a BY Draconis variable, a star that varies in brightness due to starspots coupled with the effect of rotation. As one of the nearest stars similar to the Sun, Epsilon Eridani has been the target of SETI (search for extraterrestrial intelligence) searches and often appears in works of science fiction. The galaxy was discovered by the American astronomer Francis Preserved Leavenworth in 1886.

Now Jason and the Phantom Blade team must rescue their teammate and stop a deadly . The notion that there might be inhabited extrasolar planets can be traced at least as far back as Giordano Bruno who, in his De l'infinito, universo e mondi (On the Infinite, Universe and Worlds, 1584), declared that "There are then innumerable suns, and an infinite number of earths revolve around those suns, [These worlds are inhabited] if not exactly as our own, and if not more nobly, at least no less inhabited and no less nobly. * In Battlelords of the Twenty - Third Century, Epsilon Eridani is the home star system for an alien race . .
