What is Kappa Coronae Borealis

Kappa Coronae Borealis is an orange subgiant some 99 light-years away with a confirmed planet: Kappa Coronae Borealis b, a gas giant of twice Jupiter's mass discovered in 2007 that takes 3.4 years to complete an orbit. In 2013 it also became the first subgiant ever imaged with a resolved circumstellar dust belt —that belt rings Kappa itself.

Where it is and when to see it

Kappa 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
