84 Ursae Majoris
Variable starWhat is 84 Ursae Majoris
84 Ursae Majoris is a variable blue-white B-type star 290 light-years away in the Great Bear. To its high surface temperature it adds a subtle pulsation that modern photometry detects with patience. Its light, which left in the 18th century, crosses the most-visited region of the northern sky, that Bear which any trained eye recognises from memory.
Where it is and when to see it
84 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 March: 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.
