Its story

5 Eridani is a hot blue B-type star along the long course of Eridanus, the celestial river that winds from Rigel down to the southern limits. Its surface burns well above ten thousand kelvin, giving it the blue-white tint of early-type, massive stars. From 362 light-years, its light departed in the early seventeenth century, while Kepler was still computing the elliptical orbit of Mars from Tycho's observations.
