HIP 83057
Hot blue starWhat is HIP 83057
In southern Ara burns a blue star at 519 light-years. Its light departed in the early sixteenth century, when Magellan was preparing the expedition that would complete the first circumnavigation and the Spanish court was looking toward the Pacific. It is a class B star, several times hotter than the Sun, with intense emission in the ultraviolet region of the spectrum. It is part of the steady scenery of a constellation little celebrated by the ancients.
Where it is and when to see it
HIP 83057 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.
