17 Canis Majoris
What is 17 Canis Majoris
17 Canis Majoris sits within the Great Dog, the constellation ruled by Sirius, the brightest star in the night sky. It is a white A-class star about five hundred light-years away, far too distant to rival its more famous neighbours yet hot enough to radiate in bluish-white tones. Its light set out long before the southern sky began to be charted systematically.
Where it is and when to see it
17 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.
