What is Rho Aquilae

ρ Aquilae was catalogued in the Eagle, but its proper motion proved so persistent that in 1992 it crossed the official boundary between constellations and entered the Dolphin. A white A2 main-sequence star 156 light-years away, with two solar masses, it is approaching us at 23 km/s. One of the few stars whose cartographic redrawing literally changed its home in the sky.

Where it is and when to see it

Rho Aquilae lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is August: 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.
