TOI 270 system scaled to Jupiter's moons, illustration
Illustration of The Object of Interest 270 (TOI 270) exoplanet system scaled to Jupiter's moon's orbits. TOI 270's exoplanets were discovered by NASA's Transiting Exoplanet Survey Satellite (TESS), which measures the dip in light as planets pass between the host star and TESS. TOI 270 is an M Dwarf star that is 40% smaller then the Sun. The TOI 270 planetary system lies about 73 light-years away in the constellation Pictor. The innermost planet, TOI 270 b, is likely a rocky world about 25% larger than Earth. It orbits the star every 3.4 days and has a mass around 1.9 times greater than Earth's. Due to its proximity to the star, it is thought to be around 254 degrees Celsius. The other two planets, TOI 270 c and d, are, respectively, 2.4 and 2.1 times larger than Earth and orbit the star every 5.7 and 11.4 days. All of the planets are expected to be tidally locked to the star, which means they only rotate once every orbit and keep the same side facing the star at all times.
