TOI-4155 b: A Neptune-like World in a Close Orbit

TOI-4155 is a single star located 785 light-years away, with a mass of 1.16 solar masses, a radius of 0.95 solar radii, and a temperature of 5720 K. One planet has been found orbiting this host.

That planet is TOI-4155 b, a Neptune-like world discovered in 2025 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. The planet completes an orbit every 3.32 days and has a radius of 3.21 Earth radii, a reported estimate larger than Earth's. Neptune-like planets reach up to 4 times Earth's radius, and Earth radii compare radius rather than volume.

The orbital period is the time TOI-4155 b takes to complete one orbit: its year.
