70 Ursae Majoris
What is 70 Ursae Majoris
70 Ursae Majoris glows 636 light-years away inside Ursa Major, not among the seven famous stars of the Plough but a little farther south, in a quieter region of the constellation. It is a K-class orange giant with a radius around forty times that of the Sun, an immense surface pouring out hundreds of solar luminosities into the surrounding void. It is drifting steadily toward us at over forty kilometres per second.
Where it is and when to see it
70 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 February: 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.
