Name origin
The common name ROBIN is a code name after Robin. It was assigned with this announcement as the informal designation for the newly imaged companion. The name sits with the planet in the public catalog the same way other common names accompany a TOI identifier — a recognition, not a replacement for the archive code.
The official catalog designation is TOI-7421 b. ROBIN — TOI-7421 b was announced today, September 3, 2026, as a newly imaged companion around an A-type host. The name is a code name after Robin, not a change to the TOI catalog identifier used in the archive.
