Iota Eridani
What is Iota Eridani
Iota Eridani is an orange giant set along the long, winding course of the river Eridanus. With barely thirty percent more mass than the Sun, it has swollen to eleven times its radius: a likely future of the Sun itself, glimpsed from one hundred and fifty light-years away, in the midst of helium-burning at its core.
Where it is and when to see it
Iota 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.
