Tau 3 Eridani
What is Tau 3 Eridani
Tau-3 Eridani rests just 89 light-years away, an almost familiar distance for a star visible to the naked eye. It is white, of A type, and forms part of the long procession that traces the river Eridanus meandering southward. One among many in a celestial watercourse —but its closeness makes it unusually sharp when the eye finds it.
Where it is and when to see it
Tau 3 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 October: 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.
