Sigma 2 Cancri
What is Sigma 2 Cancri
Sigma-2 Cancri is a white subgiant, a star slightly hotter than the Sun that has begun to drift past its youth after some 441 million years of steady burning. It belongs to a multiple system in the modest sign of the Crab—that small zodiacal constellation tucked almost unnoticed between bright Leo and the twin stars of Gemini. Its light crosses 194 years before reaching the human eye.
Where it is and when to see it
Sigma 2 Cancri lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is January: 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.
