What is 1 Aquarii

1 Aquarii is an orange K-class star at the head of the Water-Bearer, around 233 light-years away. Its surface, cooler than the Sun's, tints its light with a warm, ancient hue; at that range its magnitude 5.15 implies a giant tens of times more luminous than our daytime star. The light arriving tonight set out in the last quarter of the 18th century, when the first modern southern sky charts were being drawn.

Where it is and when to see it

1 Aquarii lies in the northern 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
