Hima was an inhabited planet. It had a single sun and at least four moons. The planet hosted a variety of native lifeforms, including a bird, a predatory insect, a winged insect, a fish, and a mobile aquatic plant with healing properties.
The main settlement on Hima was Requiem, above which was the Mercantile, an entrepôt for couriers controlled by the Emerald Chain. There was a large debris field in orbit containing remnants of Federation starships.
After leaving the 23rd century in the Red Angel suit, Michael Burnham emerged from a wormhole over Hima in 3189. Seconds later, she collided with Cleveland Booker's ship, causing both to crash on Hima. Burnham subsequently helped Booker obtain more dilithium from the Mercantile, allowing them to depart.
