What is 49 Leonis

49 Leonis is a triple system that harbours an eclipsing binary: two stars that, seen from Earth, periodically hide one another, dimming the system's combined light. Ernst-Joachim Meyer discovered those eclipses in 1933. The primary is an A2 main-sequence star about 429 light-years away, on the flanks of the zodiacal Lion. Through a large telescope it also resolves as a visual pair —double in two senses at once.

Where it is and when to see it

49 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
