EPSILON AURIGAE

binary star system including one of the largest known stars and having one of the longest periods (27 years) among eclipsing binaries. The diameter of Epsilon Aurigae B, a cool yellow star, has been estimated as thousands of times that of the Sun; if Epsilon Aurigae B occupied the Sun's place at the centre of the solar system, the Earth and even the remote planet Saturn would lie within the star. Epsilon Aurigae A, a yellow-white star, is measured at about 200 solar diameters. The maximum apparent magnitude of the combination is about 3.0.
