TOI-1443: A Cool Star With One Super-Earth
TOI-1443 is a star 280 light-years away with an age of 7.4 billion years. Its reported mass estimate is 0.766 solar masses, its reported radius estimate is 0.751 solar radii, and its temperature is 5220 K, all smaller or cooler than the Sun. One planet orbits this host.
That planet, TOI-1443 b, is a Super-Earth discovered in 2024 by transit, the dimming of a star's brightness as a planet crosses in front of it. Its reported radius estimate is 2.3 Earth radii, larger than Earth's, and its mass has a reported upper limit of 30 Earth masses. It completes an orbit every 23.5 days.
