Beta Canis Majoris (β CMa β Canis Majoris) is a star in the southern constellation of Canis Major the ‘greater dog’ and is located at a distance of about 500 light-years (150 parsecs) from the Earth. In the modern constellation it lies at the position of the dog’s head. It has the traditional name Murzim Al-Murzim or Mirzam which is derived from the Arabic (مرزم) for ‘The Herald’ and probably refers to its position heralding Sirius in the night sky (i.e. rising before it).
