What is Rho Serpens

Rho Serpentis belongs to the eastern half of the Serpent, the only constellation in the sky split into two disconnected parts by the intervening figure of Ophiuchus. It is an orange K-type giant at 375 light-years, a warm light that has been travelling since before the French Revolution to reach us tonight.

Where it is and when to see it

Rho 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.
