Phi 2 Orionis
What is Phi 2 Orionis
Phi-2 Orionis forms with Meissa and Phi-1 a small triangle at the hunter's head, just above the three stars of the belt. She is a yellow subgiant older than the Sun by some seven billion years and already starting to swell: with barely more mass, she has grown to eight solar radii and burns thirty times brighter. At 117 light-years she shows in miniature what the Sun will do in five billion years.
Where it is and when to see it
Phi 2 Orionis lies in the northern 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.
