11 Sagitta
Hot blue starWhat is 11 Sagitta
11 Sagittae burns as a blue B-type star in the small figure of the Arrow, an almost straight asterism wedged between the Swan and the Eagle. From 455 light-years away, its magnitude 5.54 corresponds to a body far hotter and more luminous than the Sun, helping trace the silhouette of the celestial projectile. The light arriving tonight left its surface near 1570, when Tycho Brahe had just observed the supernova that would change his life.
Where it is and when to see it
11 Sagitta lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
