TESS discovers three new planets nearby, including temperate ‘sub-Neptune’: Planetary system orbiting an unusually quiet star is ideal for future habitability searches

NASA’s Transiting Exoplanet Survey Satellite, or TESS, has discovered three new worlds that are among the smallest, nearest exoplanets known to date. The planets orbit a star just 73 light years away and include a small, rocky super-Earth and two sub-Neptunes — planets about half the size of our own icy giant.
