What is Tau Coronae Borealis

Tau Coronae Borealis is an orange star at 117 light-years, set in the diadem Dionysus placed among the stars. Its warm tone comes from a surface cooler than the Sun's, typical of giants and subgiants already past their prime. It belongs to the modest yet perfectly drawn arc of the Northern Crown, which rises each spring and slips away without fanfare.

Where it is and when to see it

Tau Coronae Borealis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: 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
