What is Theta Ursae Minoris

Theta Ursae Minoris is an orange-red giant of the Little Bear, nearly a hundred times the Sun's radius and shining with 1,600 times its light, about 856 light-years from the Solar System. Its K5 spectrum shows a mild overabundance of cyanogen in the atmosphere —a quiet chemical fingerprint— and it is closing in on us at 25 km per second. It shines circumpolar for almost the whole northern hemisphere: it never sets.

Where it is and when to see it

Theta Ursae Minoris 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
