Jedna z planet je podobn\u00e1 na\u0161emu Jupiteru, ale ob\u00edh\u00e1 hv\u011bzdu TOI-201 jednou za 53 dn\u00ed. Druh\u00e1, men\u0161\u00ed planeta jen o n\u011bco v\u011bt\u0161\u00ed ne\u017e na\u0161e Zem\u011b, ob\u00edh\u00e1 tuto hv\u011bzdu za 5,8 dn\u00ed. Prvn\u00ed z planet byla objevena v roce 2019 nedlouho po startu vesm\u00edrn\u00e9 observato\u0159e TESS. Druhou planetu pomohl charakterizovat t\u00fdm veden\u00fd \u010desk\u00fdmi astronomy provozuj\u00edc\u00ed spektrograf PLATOSpec. Krom\u011b t\u011bchto dvou planet se poda\u0159ilo zachytit z\u00e1kryt hv\u011bzdy dal\u0161\u00edm t\u011blesem, kter\u00e9 m\u00e1 ob\u011b\u017enou dobu 7,9 rok\u016f.
