What is HIP 45743

Within the long body of Hydra, the most extensive constellation in the sky, an orange dwarf burns at 452 light-years. Its light left during the Council of Trent, when the Catholic Church was reorganising its doctrine in the face of advancing Protestantism and Europe was redrawing its religious maps.

Where it is and when to see it

HIP 45743 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February: 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.
