CFHTWIR-Oph 98 B is a substellar object, either an exoplanet or a sub-brown dwarf that orbits CFHTWIR-Oph 98 A, a M-type brown dwarf.[1] The pair form a binary system.
It orbits a star but its formation as an exoplanet is challenging or impossible.[2] If its formation scenario is known, it may explain the formation of Planet Nine. Planetary migration may explain its formation, or it may be a brown dwarf.
