HIP 21515
Hot blue starWhat is HIP 21515
In Taurus, 851.7 light-years away, a blue B-type sun burns with the fury of young stars. Its light set out toward us while master masons were raising the first Gothic cathedrals and stained glass was beginning to invent Europe's interior light. A blue arrow that has crossed the whole Middle Ages and is still not spent.
Where it is and when to see it
HIP 21515 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
