MIRFAK (Alpha Persei). Perseus, the ancient hero who rescued Andromeda, climbs the northeastern sky in northern autumn evenings, bright Mirfak marking his side amidst a lovely stream of stars that lies within the northern-hemisphere autumn Milky Way.
Mirfak is a yellowish F5Ib supergiant star having about 5000 times the luminosity of the sun. The spectral type implies a diameter about 80 times that of the sun, and a mass about 11 times that of the sun.

Another stellar association is that surrounding Mirfak (α Persei), which is very prominent in binoculars. Distant moving clusters can't readily be detected since the proper motions of the stars need to be known.
The brightest star in Perseus is [6453] alpha Persei, also known by its traditional names Mirfak ("elbow") and Algenib ("the side"). Mirfak is a yellow-white supergiant lying approximately 590 light-years from Earth.

Half way between Capella and Mirfak (alpha Persei, a.k.a. Algenib) and five degrees north of this last star, are the feet of the Giraffe. Roughly half way between Algenib and the North Pole is gamma Camelopardalis, the haunch of the giraffe.
