Double Star in Corvus
Algorab comes from the Arabic word for "the crow," and it is the star in the upper left corner of the constellation Corvus, the crow. It is a nice double star with components of very unequal brightness. The brighter component, a hot blue-white star of magnitude 3, is more than 100 times brighter than the dimmer, orange component. Their angular separation makes them easy to resolve in just about any telescope.
It is not known whether these two stars are gravitationally connected.
