HIP 84731
Highly luminous starWhat is HIP 84731
In the constellation of the Altar, 2,490 light-years away, lives an orange type-K star whose light departed in the heart of classical antiquity, when Pericles governed Athens and the Parthenon was being built. It is a luminous giant: though its surface is cooler than the Sun's, its swollen size lets it pour the light of hundreds of suns into space. Its coppery tone, sustained across millennia, is that of a liturgical flame burning unwitnessed in the southern sky.
Where it is and when to see it
HIP 84731 lies in the southern 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.
