This system has a number of remarkable features, including a Sudarsky Class V gas giant that orbits its binary parent stars at a distance of about 12 light-seconds. But the most interesting feature of this system is body C 1 a, a moon with a radius of just 154 km. By comparison: Quantum World, the smallest discovered moon in the galaxy, has a radius only 15 km smaller.

The primary stars in this system are A-class and K-class, with a Sudarsky Class V gas giant orbiting just 12 light-seconds from their epicenter.

The C star has only one planet and one moon, whose irregular shape and iron-nickel composition make it look like a meatball.

The body is four times smaller than its parent planet and 70 times less massive, with a surface gravity only 0.04 Earth-normal.

Tidal forces from the C star and parent planet heat the moon's interior, producing silicate fumaroles and gas vents across the moon's surface.

(The record holder as of 3309/02/17 is Pria Thoi ZP-G d10-37 AB 4 a, with a radius of 137.38 km.)

The primary stars in this system are a class A and a class K star, with a Sudarsky Class V gas giant orbiting them just 12 light-seconds from their common barycenter.

The third star has only one planet and one moon, which's irregular shape and iron-nickel composition make it look like a meatball.

The body is four times smaller than its parent planet, and 70 times less massive, with a surface gravity only 0.04 g.

There is active volcanism on the moon: tidal forces from the C star and the parent planet heat its interior, producing silicate fumaroles and gas vents across the moon's surface.
