What is 3 Leonis

3 Leonis shines with the orange tone characteristic of a K-class star about 405 light-years away, in the regal outline of the Lion. Its surface, cooler than the Sun s, gives it that quiet amber colour that sets it apart from the rest of the field. The light falling on us tonight left around 1620, as the first European settlers were reaching the shores of North America.

Where it is and when to see it

3 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
