TOI-4156: A Nearby Star With Two Neptune-Like Planets

TOI-4156 is a star located 697 light-years away. It has a mass of 1.1 solar masses, a radius of 1.04 solar radii, and a temperature of 5990 K, which is hotter than the Sun. Two planets orbit this star, both discovered by the transit method in 2026.

TOI-4156 b and TOI-4156 c are both Neptune-like planets. A planet earns that size class when its radius reaches up to four times Earth's. TOI-4156 b has a radius of 2.54 Earth radii and a year of 4.46 days. TOI-4156 c is slightly larger, with a radius of 2.92 Earth radii, and it completes an orbit in 12.8 days. Among the listed planets, TOI-4156 b has the shortest year and the smallest radius by reported estimates, while TOI-4156 c has the longest year and the largest radius.
