DE CVn b: A Planet Orbiting Two Stars
DE CVn is a binary star system 99.6 light-years away, and one known planet orbits the pair. The host star has a mass of 0.419 solar masses and a radius of 0.425 solar radii, both smaller than the Sun's corresponding values. Its temperature is 3580 K, cooler than the Sun's.
DE CVn b is a circumbinary planet, meaning it orbits both stars of the binary system rather than one star alone. It was discovered in 2018 by Eclipse Timing Variations. Its mass is 3820 Earth masses, roughly 12 times Jupiter's mass and larger than Earth's, and its orbital period is 4100 days.
