What is Lambda Coronae Borealis

Lambda Coronae Borealis shines near the semicircle of stars forming the Northern Crown, one of the sky's most recognizable and compact constellations. It is an F-type star some 136 light-years away, hotter and whiter than the Sun. Its light accompanies Alphecca, the central jewel that gives its name to the mythical diadem cast by the goddess Ariadne into the firmament.

Where it is and when to see it

Lambda 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
