    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.[2][3] The exoplanet is about 70% larger in diameter than Earth, and roughly five times as massive.[4]

    Discovery

    TOI-1452 b was discovered by an international team led by astronomers from the Université de Montréal,[5][6] using data from NASA’s Transiting Exoplanet Survey Satellite (TESS).[1][7] The discovery was first reported in June 2022.[1]
