10 Lacerta
Hot blue starWhat is 10 Lacerta
10 Lacertae is a blue colossus of O-type —one of the rarest and hottest stellar classes— more than 1,700 light-years away in the small constellation of the Lizard. Despite that vast distance, it reaches magnitude 4.89 thanks to an immense luminosity and a fierce stellar wind. It serves as a classical reference for calibrating other O stars and slips between Cygnus, Cepheus and Andromeda, stitched quietly into the bright fabric of the Milky Way.
Where it is and when to see it
10 Lacerta lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: 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.
