Lambda Aquilae
Hot blue starWhat is Lambda Aquilae
Lambda Aquilae shines blue-white at the head of the Eagle, just 124 light-years away, with a constancy so extreme that the Hipparcos satellite ranked it among the least variable stars in the sky. Three times the Sun's mass and fifty-five times its light, it shares a system with an unseen red-dwarf companion. A cold, steady, almost metronomic light within one of summer's most recognizable asterisms.
Where it is and when to see it
Lambda Aquilae lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is July: 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.
