Lambda Canis Majoris
Hot blue starWhat is Lambda Canis Majoris
Lambda Canis Majoris burns with B-type blue light some 424 light-years away, in a constellation that chases Orion across the winter sky. A few degrees from Sirius —the brightest star visible from Earth— its glow is eclipsed by sheer proximity. It is an example of how the sky's geometry can make modest what would, elsewhere, be a lead.
Where it is and when to see it
Lambda 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.
