TIC 172900988b is a transiting circumbinary planet detected from a single sector of TESS data. The planet transited the primary star and then 5 days later it transited the secondary star. Archival data from ASAS-SN, Evryscope, KELT, and SuperWASP reveal a prominent apsidal motion of the binary orbit, caused by the dynamical interactions between the binary and the planet. The system is accessible for high-resolution spectroscopic observations, e.g. Rossiter-McLaughlin effect and transit spectroscopy.
