Achernar is a hot blue-white main sequence star just cracking the top ten brightest stars in the sky at #9. Of these top ten, Achernar is the also the bluest and hottest of them. It is best seen from the Southern Hemisphere in November. While on the main sequence for star clasifications, it is thought to have recently exhausted the hydrogen. In real space, Achernar has actually flattened out into an oblate spheroid shape due to its extreme rotational speed.
