This system houses two small rocky ice moons around a Class III Gas Giant, sharing a close orbit. The first one, body ABCD 1 a (nicknamed "big brother") has a radius of 649 km and a surface gravity of 0.6 g, while the second one, body ABCD 1 b ("baby brother"), has a radius of 584 km and a surface gravity of 0.7 g. They orbit a common barycenter and are so close to each other that you're still "departing" from one when you're already "arriving" at the other.

The two "taters" (as named by the discoverer) are landable, and both offer good sights and opportunities for photos, especially when their parent gas giant is visible. The moons have surface geological activity - Major Silicate Vapour Geysers - but there's no atmosphere, nor surface life.

Body ABCD 1 d is quite a rare sight too: it's a highly inclined, ringed, thin argon atmospheric icy world that hosts life.

This rare combination grants beautiful views featuring the parent gas giant, its three other satellites and the nearby Heart Nebula star cluster - and the neighbouring Soul Nebula.
