What is HIP 45544
Some 345 light-years away, an orange class K star hangs in Vela like a steady ember. Its glow set out around 1681, in the heart of Newton's age, before the Principia was published but as calculus and celestial mechanics were taking shape. Cooler than the Sun and with a swollen surface, its warm tone sets it apart among the scattered beacons of the southern hemisphere.
Where it is and when to see it
HIP 45544 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.
