NASA's TESS mission discovers 2 new rocky exoplanets
NASA's TESS mission has spotted two rocky exoplanets orbiting a nearby star called TOI-2322, about 195 light-years from us.
Scientists detected them by watching tiny dips in the star's brightness—a classic sign that planets are passing in front.
TOI-2322 b and c
TOI-2322 b is close to Earth's size, circles its star every 11 days, and is super hot at around 330°C.
Its neighbor, TOI-2322 c, is almost twice as wide as Earth and much heavier—about 18 times our planet's mass—with a dense structure like Earth's layers.
Both were confirmed using space telescopes and ground-based tools, showing how teamwork in astronomy keeps revealing new worlds beyond our solar system.
