What is 45 Cancri

45 Cancri lies 927 light-years away, in one of the faintest zodiacal constellations. It is a white A-type star, young and hot, whose modest brightness from Earth belies its true power: at that distance, a star like this far outshines the Sun. Cancer holds within its bounds the Beehive Cluster —M44—, one of the oldest stellar groups known to humanity.

Where it is and when to see it

45 Cancri lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is January: 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
