Zeta Canis Majoris (ζ CMa / ζ Canis Majoris) is a spectroscopic binary in the constellation Canis Major. It also has the traditional name Furud or Phurud, from the arabic فرد al-furud meaning the solitary ones. ζ Canis Majoris is approximately 336 light years from Earth.

Zeta Leporis (880 words)
Zeta Leporis is a bluish white main sequence dwarf star of spectral and luminosity type A2-3 Vann.
Since Zeta Leporis is much older, its observed dust grains were not there when the star first formed, and so they must be generated through some secondary process such as collisions between larger objects.
The orbit of an Earth-like planet (with liquid water) around Zeta Leporis may be centered around 3.9 AU -- around the central orbital distance of the Main Asteroid Belt in the Solar System -- with an orbital period of several years.

Known as the Large Dog (Canis Minor is the Small Dog), it was associated with the figure of a dog by many cultures; the ancient Greeks identified it as one of Orion's hunting dogs, while the Scandinavians called it Sigurd's dog.
Other bright stars in Canis Major are Adhara (Epsilon Canis Majoris), Mirzam (Beta Canis Majoris), and Wezen (Delta Canis Majoris).
