NSVS 14256825 and Its Circumbinary Planet
NSVS 14256825 is a binary star system 2680 light-years away. The host star has a mass of 0.47 solar masses, a radius of 0.202 solar radii, and a temperature of 40000 K. Its reported mass and radius estimates are smaller than the Sun's, while its reported temperature is hotter than the Sun's. One planet orbits this host.
That planet, NSVS 14256825 b, was discovered in 2019 by Eclipse Timing Variations. It is a circumbinary planet, meaning it orbits both stars of the binary system rather than one star alone. Its minimum mass is 4500 Earth masses, a lower bound on its true mass that is larger than Earth's and roughly 14.2 times Jupiter's mass. It completes an orbit every 3230 days.
