ROXs 42 B b: A Young Circumbinary World

ROXs 42 B is a binary star system 468 light-years away, and its listed planet orbits both stars rather than one alone. The host star is an M0 dwarf, a small, cool red dwarf, with a mass of 1 solar masses. It is very young, with an age of 0.0027 billion years.

One planet is reported around this host: ROXs 42 B b, discovered by imaging in 2013. It is a circumbinary planet, meaning it orbits both stars of the binary system. Its mass estimate is 2860 Earth masses, larger than Earth's and roughly 9 times Jupiter's mass. No orbital period is reported for ROXs 42 B b.
