HIP 72552
What is HIP 72552
In the silhouette of the Herdsman, that celestial shepherd who follows the Wain, shines a white type-A star, hotter and more luminous than the Sun. Its light set out 321 years ago, when Bach was still a young organist in Arnstadt and musical Baroque was beginning to unfold its fugues and counterpoints. It has travelled in silence while human music was becoming a cathedral, arriving untouched to us.
Where it is and when to see it
HIP 72552 lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is April: 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.
