HIP 75257
Highly luminous starWhat is HIP 75257
Orange, luminous, profoundly distant —1942 light-years away— in Boötes, the celestial herdsman. Its light departed around 84 AD, when emperor Domitian ruled Rome and gladiators were inaugurating the newly finished Colosseum. This K giant, far brighter than our Sun, released back then the photon that any human catches tonight.
Where it is and when to see it
HIP 75257 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: 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.
