17 Ursae Majoris
What is 17 Ursae Majoris
17 Ursae Majoris is a variable K-type giant, long past the main sequence, set far from the bright stars of the Great Bear at 720 light-years. Its modest magnitude of 5.28 calls for a dark sky to be picked out. It approaches the Solar System at 30 km per second, a warm light that left when Renaissance humanists were drafting their first European treatises.
Where it is and when to see it
17 Ursae Majoris 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

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
