What is 7 Persei

7 Persei sits 820 light-years away, in the constellation of Perseus, the hero who bore the head of Medusa. It is a yellow G-type star, giant and more luminous than the Sun, sending us tonight a light that left its surface when the kingdoms of Castile and León were splitting apart after the death of Alfonso VII. Perseus is famous for the Perseids, the best-known meteor shower of the northern summer.

Where it is and when to see it

7 Persei lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is November: 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
