Sirius is the brightest star in the northern sky. Often appearing low on the horizon, it has a distinctive sparkling appearance. Although the brightest star in our skies, this is mainly due to it's proximity to Earth (8.6 light years) and not due to extraordinary luminosity.
Sirius also has a little homie called Sirius B. Sirius B is the burnt out husk of a large sun-like star. Some say that the orbital dynamics of the system were communicated to certain ancient African tribes by aliens, although this is unlikely. There is a hypothesised third member of the Sirius system awaiting discovery.
