What is HIP 90991
This white light left Scutum in the 19th century, when refracting telescopes were growing in size and the first modern observatories were rising. It is an A-type star, hot and bluish-white, several times more luminous than the Sun. Scutum is a small constellation, yet it is crossed by one of the densest and brightest regions of the visible Milky Way.
Where it is and when to see it
HIP 90991 lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is June: 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.
