HIP 43783
Hot blue starWhat is HIP 43783
It burns white-hot in Carina, one of those B-class stars whose surface far outshines the Sun in heat. Its light set out around 1706, when Royal Society astronomers were debating Halley's first results on periodic comets. Three centuries later, that same wave reaches the keel of the old Argo, in a southern sky it has scarcely let cool.
Where it is and when to see it
HIP 43783 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
