What is 46 Leonis

46 Leonis is an M-type red giant 694 light-years away, a slow ember inside the body of the Lion. Its surface, far cooler than the Sun's, radiates in reddish tones betraying an aged and immense star. It shares the sky with the region where, every November, the Leonids seem to spring —debris from comet Tempel-Tuttle.

Where it is and when to see it

46 Leonis lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is February: 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.
