TOI-1338 is a binary star system located in the constellation Pictor, about 1,320 light-years from Earth. It is orbited by two known circumbinary planets, TOI-1338 b, discovered by the Transiting Exoplanet Survey Satellite (TESS) and BEBOP-1c, discovered by the Binaries Escorted By Orbiting Planets project.
==Discovery and nomenclature== The circumbinary planet TOI-1338 b was found in July 2019 by Wolf Cukier, a 17-year-old high school student who joined the Goddard Space Flight Center as a summer intern. The acronym TOI stands for "TESS Objects of Interest." Cukier studied data provided by volunteers of the Planet Hunters citizen science project, looking through data that had been flagged as an eclipsing binary. Cukier and six of the Planet Hunter volunteers are co-authors of the publication regarding the planet.
