15 Arietis
Variable starWhat is 15 Arietis
15 Arietis is an M-type variable red giant some 559 light-years away, in the small constellation of the Ram. Its cool atmosphere modulates its brightness around magnitude 5.68, beyond the comfortable threshold of the unaided eye. Aries was the first zodiacal sign in many ancient traditions and still marks the historical vernal point; among its stars, this variable beats with a slow rhythm indifferent to the human calendar.
Where it is and when to see it
15 Arietis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is October: 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.
