Planets in binary systems, S-type
The binary star system HD 213240 consists of the components A and C. The letter B was already used by the WDS survey from 1901 to describe another object. However, it turns out that the B component is not physically associated with the binary. The planet orbiting the A component was discovered in 2001 by Santos and collaborators.
