TIC 18942729 b: A Super-Earth in a One-Planet System

TIC 18942729 is a star located 376 light-years away, and it hosts exactly one known planet. The star's reported mass estimate is 0.652 solar masses, smaller than the Sun's, while its radius is 0.825 solar radii, also smaller than the Sun's. Its temperature of 4170 K is cooler than the Sun's.

The sole planet, TIC 18942729 b, is classified as a Super-Earth. This size class compares a planet's radius with Earth's: a Super-Earth can reach up to 2.5 times Earth's radius. TIC 18942729 b's radius is 2 Earth radii, larger than Earth's. It was discovered by the transit method in 2026, and its orbital period is 0.998 days.
