Oberon III

Oberon III is a protoplanet that orbits third from the star of the unclaimed [Oberon system](https://robertsspaceindustries.com/galactapedia/article/VYLdlgMqop-oberon-system). Alongside its sister protoplanet [Oberon IV](https://robertsspaceindustries.com/galactapedia/article/0dXd5mQWLd-oberon-iv), it is theorized that it formed in the Oberon system after its original star went supernova and collapsed into a neutron star. However, it failed to gain enough mass from the dust and gas of the newly-formed accretion disk to become a full planet.
