Kappa 2 Sagittarii
What is Kappa 2 Sagittarii
Kappa-2 Sagittarii is a visual binary 312 light-years away, two white A-type stars orbiting a common centre over a period of about 700 years. Its components are separated by two arc-seconds with an orbital eccentricity of 0.4, a serene couple moving in slow motion against the backdrop of the Milky Way, in the richest region of the Sagittarius sky. The primary alone radiates some 38 times the Sun's light from a surface burning near 7,990 K.
Where it is and when to see it
Kappa 2 Sagittarii lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
