What is 101 Aquarii
101 Aquarii closes the numbered procession of the Water Bearer with a polished, serene white light of class A, set almost three hundred light-years from Earth. It lies in a region of the sky ruled by faint figures —Aquarius, Piscis Austrinus— where it acts as a quiet coda to Flamsteed’s catalogue for this constellation. Its glow comes from a surface a few thousand degrees hotter than the Sun’s.
Where it is and when to see it
101 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 September: 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.
