TOI-1338 b is a gas giant circumbinary exoplanet in the constellation Pictor orbiting around the binary star system TOI-1338, first identified by then-17-year-old Wolf Cukier. It was the first circumbinary planet discovered by the Transiting Exoplanet Survey Satellite (TESS).[4] It was found on 31 July 2019 and announced on 6 January 2020.[5][6] It is around 6.9 times the diameter of Earth.[7] It orbits 1318 light years away from Earth[3], which calculates to 12.5 quadrillion kilometers, or 7.7 quadrillion miles.
Discovery
Wolf Cukier, a 17-year-old attending Scarsdale High School in New York at the time, joined the Goddard Space Flight Center in 2019 to work as a summer intern. While studying data that was flagged as an eclipsing binary (provided by volunteers of the Planet Hunters citizen science project), he found TOI-1338 b on his third day of interning.[8][9] He and 6 of the volunteers are co-authors of the publication regarding TOI-1338 b.[1] Cukier then attended Princeton University and graduated in 2024.
The discovery of TOI-1338 b was announced on 6 January at the 235th American Astronomical Society meeting in Honolulu, Hawaii.[10] In February 2021, a petition was launched calling for TOI-1338 b to be renamed SOPHIE in honor of late Scottish musician Sophie.[11][12] The petition was supported by Charli XCX and Caroline Polachek.[11] The petition was unsuccessful in renaming TOI-1338 b, however, the International Astronomical Union announced that the minor planet 1980 RE1 would be given the permanent name Sophiexeon in June 2021.[13]
