The TOI-1452 star system is 99 light-years away from Earth,[5] located in the constellation of Draco. It is a binary pair of dim red dwarf stars separated by only 96 astronomical units (AU). A notable feature of this system is the presence of an exoplanet around one of the stars, designated as TOI-1452 b.[6] It is two M4 dwarf stars that were observed by TESS as a priority, since they are on the cool dwarf list, a list of high-priority orange-red and red dwarf stars, that was uploaded to TESS. It is a flare star, with a flare observed by TESS where the star brightened by 5%. The secondary star is often distinguished from the first with the name "TOI-1760".[7]

TOI-1452 b was discovered by an international team led by astronomers from the Université de Montréal,[8][9] using data from NASA’s Transiting Exoplanet Survey Satellite (TESS).[1][10] The discovery was first reported in June 2022.[1]
