HIP 42834
Hot blue starWhat is HIP 42834
A blue B-type star burns in Vela at about 1853 light-years, a distance its light began to cross around the second century, when the Roman Empire reached its greatest extent and ancient cartographers were tracing the first global trade routes. Its surface easily exceeds 10 000 degrees, tens of times hotter and thousands of times brighter than the Sun. It is a youthful blaze destined to live briefly and intensely.
Where it is and when to see it
HIP 42834 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is March: 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.
