46 Eridani
Variable starWhat is 46 Eridani
46 Eridani throbs in the celestial river of Eridanus, that long stellar current descending from the feet of Orion toward the south. It is a massive blue-white B-type variable star some 828 light-years away —its brightness is not entirely constant and shifts with the slow breathing of massive stars—. Its light began its journey around the twelfth century, when Europe was raising its first Gothic cathedrals.
Where it is and when to see it
46 Eridani lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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.
