TOI-1452 b

TOI-1452 b is a confirmed super-Earth exoplanet, possibly a water world, orbiting a red-dwarf star TOI-1452 about 100 light-years away in the Draco constellation. The exoplanet is about 70% larger in diameter than Earth, and roughly five times as massive.

System
The TOI-1452 star system is 99 light-years away from Earth, 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. 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".

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