Delta Scutum
Variable starWhat is Delta Scutum
Delta Scuti gives its name to an entire class of variable stars: the pulsating Delta Scuti family of white or yellow-white giants that beat with periods of hours, contracting and expanding in radial and non-radial oscillations. This is the prototype star, the one that defined the family. At 200 light-years away, in the small constellation of the Shield, its brightness varies softly every four and a half hours, like a cosmic heartbeat.
Where it is and when to see it
Delta Scutum lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
