Auriga (constellation) horizon. A large constellation, with an area of 657 square degrees, it is half the size of the largest constellation, Hydra. Its brightest star, Capella, is an unusual multiple star system among the brightest stars in the night sky. Beta Aurigae is an interesting variable star in the constellation; Epsilon Aurigae, a nearby eclipsing binary with an unusually long period, has been studied intensively. Because of its position near the winter Milky Way, Auriga has many bright open clusters in its borders, including M36, M37, and M38, popular targets for amateur astronomers. In addition, it has one prominent nebula, the
Hercules (constellation) the Sun's motion with respect to the Local Standard of Rest. This is located within the constellation of Hercules, around coordinates Right Ascension and Declination . The north pole of the supergalactic coordinate system is located within this constellation at Right Ascension and Declination . Hercules has no first or second magnitude stars. However, it does have several stars above magnitude 4. Alpha Herculis, traditionally called Rasalgethi, is a triple star system, partly resolvable in small amateur telescopes, 359 light-years from Earth. The primary is an irregular variable star; it is a bright giant with a minimum magnitude of 4
