TIC 154870955 b: A Neptune-Like Planet Around a Cool Dwarf

TIC 154870955 is a star 739 light-years away with a mass of 0.828 solar masses, a radius of 0.724 solar radii, and a temperature of 5000 K. Its mass, radius, and temperature are all smaller or cooler than the Sun's. One planet is known to orbit this host.

That planet is TIC 154870955 b, a Neptune-like world discovered by transit in 2026. A transit occurs when a planet passes in front of its star from our viewpoint, causing a small dip in observed brightness. TIC 154870955 b orbits every 7.97 days and has a radius of 3.09 Earth radii, larger than Earth's. In size classification, a Neptune-like planet reaches 4 times Earth's radius.
