TOI-269 b: A Neptune-like Planet Orbiting a Small Red Dwarf
TOI-269 is an M2 V star, an M-type main-sequence dwarf, located 186 light-years away. Its measured mass is 0.392 solar masses and its radius is 0.398 solar radii. The star's reported temperature is 3510 K, cooler than the Sun's.
One planet orbits this host. TOI-269 b is a Neptune-like planet discovered by the transit method in 2021. Its radius is 2.77 Earth radii, larger than Earth's, and its mass is 8.8 Earth masses, also larger than Earth's. Its mean density is 2.28 g/cm³, 0.414 times Earth's.
TOI-269 b completes an orbit every 3.7 days.
