Achernar (Alpha Eridani) is the brightest star in the constellation Eridanus and the ninth brightest star in the sky. It is located 144 ly away and it is a bright supergiant star visible in the southern part of the night sky. It remains permanently below the horizon from many densely populated portions of Earth's northern hemisphere.
It is the least spherical star in the Milky Way studied to date, spinning so rapidly that its equatorial diameter is more than 50% greater than its polar diameter. | |||||||||||||||
