TOI-1873 b: A Neptune-Like World in a One-Planet System
TOI-1873 is a star located 594 light-years away. It has a mass of 1.01 solar masses, a radius of 0.972 solar radii, and a temperature of 5700 K. One planet is known to orbit this host.
That planet is TOI-1873 b, a Neptune-like world discovered by the transit method in 2026. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness; repeated dips help establish orbital periods. TOI-1873 b completes an orbit every 7.01 days. Its radius is 2.86 Earth radii, larger than Earth's. In the size classification used for planets, a Neptune-like planet reaches 4 times Earth's radius.
