NASA's TESS telescope confirmed two rocky exoplanets, TOI-2322 b and TOI-2322 c, orbiting the K-type star TOI-2322, 195 light-years away.
TOI-2322 b is Earth-sized, with a mass under 2.03 times that of Earth; TOI-2322 c is about 18 times Earth's mass.
Both planets have short orbital periods and high temperatures, aiding studies on rocky exoplanet formation.
The star's rotation poses challenges for detecting planetary signals, offering a chance to improve detection methods.
