Theta Persei
Nearby starWhat is Theta Persei
Theta Persei lies just 36 light-years away, a solar neighbour of spectral type F7, 1.3 times the Sun's radius and slightly hotter. It shines with a calm yellow-white light in a constellation otherwise dominated by distant giants like Mirfak and Algol. The light reaching us tonight set out around 1990: a recent conversation, on a stellar scale, between Perseus and us.
Where it is and when to see it
Theta 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
If you don't have an account yet, we'll ask for an email to confirm it's you: we send you a link and that's it, no password.
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.
