Capella looks like one star, but it’s actually four stars. Capella is a four star system consisting of two binary stars.

Star A in the Capella system is what is a spectroscopic binary. Both Capella Aa and Capella Ab, as they’re called, are roughly 10 times the diameter of the sun. Both of them emit about 80 and 50 times brighter than the sun, respectively.

Capella Aa and Ab are yellow giant stars at the end of their normal lives. The two Capella stars are in transition from the smaller and hotter stars to the cooler and larger red giants they should eventually become in their final phase.

The second pair, Capella H and Capella L, are small red dwarfs. Both are about 10,000 astronomical units (AU) from the first pair. Astronomers measure the combined magnitude of this system as 0.08.
