What is 51 Aquarii
51 Aquarii is a white A-type star about 406 light-years away, in the celestial pitcher of the Water-Bearer. Its 5.8-magnitude glow makes it a quiet companion to the constellation s better-known stars. Its light, set out at the start of the seventeenth century, travelled while Galileo was mapping the Moon and Kepler reordering the solar system; it now reaches us with the cool white edge of a distant beacon.
Where it is and when to see it
51 Aquarii lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
