15 Canis Majoris
Variable starWhat is 15 Canis Majoris
15 Canis Majoris burns blue and B-class, some 1,217 light-years away within the Greater Dog —the constellation that forever pursues Orion. It is a variable: its brightness shifts in a faint rhythm only instruments can read, a quiet signal that its atmosphere trembles. A silent hunter among the embers of the winter sky.
Where it is and when to see it
15 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.
