SR 12 AB is a binary star system, and its reported planets number one. The host star has a radius of 1.1 solar radii and a temperature of 3830 K. That temperature is cooler than the Sun's.
The single known planet, SR 12 AB c, is a circumbinary planet, meaning it orbits both stars of the binary system rather than one star alone. It was discovered by imaging in 2010. Its reported mass estimate is 4130 Earth masses, which is larger than Earth's and roughly 13 times Jupiter's mass. No orbital period is reported for SR 12 AB c.
SR 12 AB c's mass estimate is the last useful fact here: a massive world circling two stars, with a mass roughly 13 times that of Jupiter.
