74 Ophiuchi
What is 74 Ophiuchi
74 Ophiuchi is a G8III giant near the boundary with Serpens Cauda, regarded as a probable binary system. Its primary, now on the horizontal branch, fuses helium in its core and has grown to ten and a half solar radii, radiating 66 times the Sun's luminosity at an effective temperature of 5,073 K. It is roughly 1.7 billion years old and reaches us from 260 light-years away.
Where it is and when to see it
74 Ophiuchi lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is June: 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.
