TESS Telescope Discovers Two New Super-Earths in Our Solar System
In an exciting new discovery, NASA’s Transiting Exoplanet Survey Satellite (TESS) has identified two super-Earth exoplanets orbiting a nearby star known as HD 21749. HD 21749 is a K-type dwarf star located 53 light-years away in the constellation Reticulum. These newly discovered exoplanets, HD 21749b and HD 21749c, are the first super-Earths detected by TESS and represent a major milestone in our understanding of exoplanetary systems. HD 21749b has a radius about three times that of Earth, and orbits its star every 36 days. HD 21749c is roughly twice the size of Earth and orbits its star every eight days. Both planets are located within the star’s habitable zone, meaning they may be capable of hosting liquid water on their surfaces.
