LS Canis Majoris is an eclipsing binary star located around 1,510 light years from Earth in the constellation Canis Major. Its apparent magnitude ranges from 5.63 to 5.79, so it is faintly visible to the naked eye. The orbital period of binary pair and the period of light variation is 70.048 days.[1]
The star's variability was first detected in the Hipparcos satellite data, and it was given its variable star designation in 1999.[8]
