TIC 423703298 b: A Neptune-Like World in a Distant System

TIC 423703298 is a single-star system located 444 light-years away. Its host star has a reported mass estimate of 0.691 solar masses, a radius estimate of 0.73 solar radii, and a temperature of 4420 K. The star's mass, radius, and temperature are all smaller or cooler than the Sun's. One known planet orbits this host: TIC 423703298 b.

TIC 423703298 b was discovered by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness; repeated dips help establish orbital periods. The planet completes an orbit every 4.04 days. Its reported radius estimate is 2.77 Earth radii, larger than Earth's. Because that radius falls within the range for its size class, TIC 423703298 b is classified as Neptune-like.
