What kind of star is Beta Eridani?
giant star
β Eridani has a spectral type of A3 III, with the luminosity class III indicating that this is a giant star which has consumed the hydrogen at its core and evolved away from the main sequence. The effective temperature of the outer envelope is about 8,104 K, which gives the star a white hue typical of A-type stars.
