Exoplanet TOI-1634 b is the biggest known with close orbit to its star

Astronomers led by Teruyuki Hirano discovered two new rocky exoplanets orbiting very close to their stars. TOI-1634 b and TOI-1685 b both orbit red dwarf stars with about half the mass of Sun. One year on these planets lasts less than a day, making them ultra short period exoplanets. TOI-1634 b is the biggest known exoplanet to have this short year.
