What is 18 Leonis

18 Leonis is an orange K-type giant in Leo, around 512 light-years away from Earth. Its warm hue, unlike the cool white of most catalogued Flamsteed stars, betrays a surface temperature lower than the Sun's —even though in sheer size and total luminosity it dwarfs our star by far. It pulses red along the lion's back, well away from the showy gleam of Regulus and Algieba.

Where it is and when to see it

18 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
