TOI-2406 and Its Neptune-Like Planet
TOI-2406 is an M4 V star, a small, cool red dwarf, located 181 light-years away. Its reported mass estimate is 0.162 solar masses, its reported radius estimate is 0.204 solar radii, and its reported temperature is 3100 K. One planet is known to orbit this host.
That planet is TOI-2406 b, a Neptune-like world discovered by transit in 2021. Its radius is 2.86 Earth radii, larger than Earth's, and its mass is a reported upper limit of 15.6 Earth masses. It completes an orbit in 3.08 days.
The star's reported mass and radius estimates are smaller than the Sun's, and its reported temperature is cooler than the Sun's.
