VY Canis Majoris is a remote red hypergiant located approximately 3,800 light-years away from Earth. It can be seen at latitudes between 60 degrees and -90 degrees.  At the other extreme in size is RX J0720.4-3125, a neutron star with a radius of around 5 km. Il resto della costellazione si estende a sud di Sirio, seguendo parallelamente la linea della Via Lattea australe, fino agli oltre 30° di declinazione sud.  To the Boorong people of Victoria, Sigma Canis Majoris was Unurgunite (which has become the official name of this star), and its flanking stars Delta and Epsilon were his two wives.

The official constellation boundaries, as set by Belgian astronomer Eugène Delporte in 1930, are defined by a quadrilateral; in the equatorial coordinate system, the right ascension coordinates of these borders lie between 06h 12.5m and 07h 27.5m , while the declination coordinates are between −11.03° and −33.25°. If you have a dog, want a dog, or just plain like dogs, you've come to the right place for all kinds of information about living with and loving dogs..
