Planet four in this system is a class I gas giant with an exceptionally wide outermost ring, coming in at 4.4 million kilometers in radius.
The system's main attraction is the gas giant's seventh moon. 4 G is a ringed icy moon with a thin nitrogen atmosphere and a steep inclination of 67 degrees around the gas giant. It orbits the gas giant at 0.05 AU and the resulting view is stunning.

From the surface of the planet, the giant's outer ring can barely be seen through the planet's atmosphere during the day.

However, during the night it is starkly visible, and along the moon's terminator it remains visible even through the twilight atmosphere.

In addition to this moon, the giant hosts a total of six shepherd moons between its second and third rings, with two sets of moons in close and fast binary orbits.

Moons 4 B and 4 D are host to powerful geysers.

The system also hosts a large ammonia world with wispy clouds.
