55 Leonis
What is 55 Leonis
55 Leonis is a yellow-white F-type star in the body of the Lion, about 146 light-years away. Its light began the journey around 1880, when Edison was patenting the incandescent bulb and the urban night was starting to vanish as an astronomical spectacle. Slightly hotter than the Sun, it offers a white light barely tinted with yellow, discreet within a constellation dominated by the calls of Regulus and Denebola.
Where it is and when to see it
55 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 March: 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

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.
