What is Epsilon Serpens

Epsilon Serpentis traces one of the joints of the Serpent, that rare constellation split in two by Ophiuchus. It is a white type-A star some 70 light-years away, close enough that its light travels roughly a human lifetime before crossing paths with ours. On Greek charts it marked the gleaming body of the reptile held by the celestial healer.

Where it is and when to see it

Epsilon Serpens lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is May: 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

Write my signature

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.
