Omicron 2 Canis Majoris
Variable starWhat is Omicron 2 Canis Majoris
Omicron-2 Canis Majoris is a blue supergiant whose light takes more than twenty-seven centuries to reach us. It belongs to the Alpha Cygni family of variables —stars so massive they pulse slowly while burning their fuel at a furious pace. To watch it tonight is to glimpse a beacon ignited in the Iron Age, still travelling through the winter sky of the hunter.
Where it is and when to see it
Omicron 2 Canis Majoris lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is January: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall
Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.
A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
