What is Nu 2 Coronae Borealis

Nu-2 Coronae Borealis is an orange K-type giant about 594 light-years away, on the delicate half-circle of the Northern Crown. Its name pairs it with the visual neighbour Nu-1: together they form one of those optical doubles the eye learns to recognise under good darkness, though their true distances are separated by an abyss. The crown welcomes its discreet light without it ever rivalling the diadem's central jewels.

Where it is and when to see it

Nu 2 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
