Kepler-1720 b: A Neptune-Like World in a Distant System
Kepler-1720 is a star located 2050 light-years away, with a mass of 0.937 solar masses, a radius of 0.85 solar radii, and a temperature of 5580 K. Its reported temperature is cooler than the Sun's. One planet is known to orbit this host.
Kepler-1720 b is a Neptune-like planet discovered by the transit method in 2021. 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. This planet completes an orbit every 12.7 days and has a radius of 3.22 Earth radii, an estimate larger than Earth's. In size classification, Neptune-like planets reach up to 4 times Earth's radius.
