The Crater features a full ecosystem of flora and fauna. The Aurora is located a few meters above the surface, in relatively shallow water. The known planet is almost completely covered in water, except for a few islands, and features a variety of submerged biomes.
There are three known major ecosystems on the planet: the Crater, Sector Zero, and the Dead Zone, the latter of which covers the majority of the planet. It also harbors two moons, one being very close to the planet, causing frequent solar eclipses.
Planet 4546B itself is a water planet smaller than Earth with a breathable oxygen-nitrogen atmosphere. There are at least ten other celestial bodies in the system, each of which is larger than Earth's Moon. The “B” means that 4546B was the first planet discovered around the star 4546 (or 4546A). Planet 4546B is located in the outer reaches of the Ariadne Arm, orbiting around the star 4546.
