What is 66 Eridani

66 Eridani is a B-type variable star some 309 light-years away, embedded in the long celestial channel of the river Eridanus. Its hot, blue-tinted atmosphere flickers gently near magnitude 5.12, a pulsation only photometric monitoring reveals clearly. Eridanus winds from the feet of Orion toward the south, and among its many stellar meanders this blue variable adds a kinetic note to the flowing river of light.

Where it is and when to see it

66 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 December: 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.
