Kepler-1708 and Its Jupiter-Like Planet

Kepler-1708 is a star located 5440 light-years away, and it hosts one known planet. The star is 3.16 billion years old, with a mass of 1.09 solar masses and a radius of 1.12 solar radii. Its temperature is 6160 K, and its reported mass and radius estimates are each larger than the Sun's, while its reported temperature is hotter than the Sun's.

The planet, Kepler-1708 b, was discovered in 2021 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. Kepler-1708 b completes one orbit every 737 days. It is classified as Jupiter-like because its radius exceeds 4 times Earth's radius. Its radius is 9.96 Earth radii, larger than Earth's, and its mass is a reported upper limit of 1462.0106722 Earth masses.
