2181 Arion

Named after the equine son of Demeter and Poseidon in Greek mythology, 2181 Arion is the second planet from the star Psi Tophet. Residing in a forgotten corner of the galaxy, this rocky planet was discovered by the Human Systems Alliance using deep-space probes in 2181, but it has never been explored by Humans or any other known species. From information collected remotely, its atmosphere appears to consist largely of hydrogen and helium and its frozen surface is encrusted in thick layers of ice.
