TOI-640 b is an exoplanet that was suspected since 2019,[1] discovery been confirmed by TESS team in January 2021. It is located 1115 light years away from Earth, orbiting primary F-class star[2] in the binary star system with red dwarf[3] and has an orbital period of 5 days.[4][5]
The planet orbits its host star nearly over poles, misalignment between orbital plane and equatorial plane of the star been equal to 104±2°[2]
