Hidden from early surveys by reflective objects in Dar'hegah's asteroid belt, H-505 is a frigid world with a krypton-nitrogen atmosphere.
Hypervelocity impact crater (largest)
Rim diameter: 402 km
Depth: Approx. 2.1 km
Ejecta: Mineral deposits, heavy metals
This is the largest of multiple impact craters, suggesting a swarm of debris—possibly from the asteroid belt—struck H-505 in the distant past.
