HIP 20234
Hot blue starWhat is HIP 20234
In Perseus, beside the Medusa's head the hero holds, shines a blue giant, fiery and early. Its light began its journey 1,084 years ago, when the caliphs of Córdoba were translating Aristotle and medieval Europe was raising its first Romanesque cathedrals. Far hotter and more luminous than the Sun, its sapphire colour belongs to a star that will live but a cosmic blink before exploding.
Where it is and when to see it
HIP 20234 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is December: 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.
