What is 15 Leonis

15 Leonis is a white A-type star lying some one hundred and sixty light-years away, in a constellation that in spring clearly traces the figure of the Lion. Its clean, serene light departed in the late nineteenth century, when astronomers were beginning to classify the stellar spectrum methodically. It stands as a discreet point among the many that compose the feline silhouette, faithful to its brightness for millennia.

Where it is and when to see it

15 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
