2MASS J01033563-5515561 A and Its Circumbinary Planet

2MASS J01033563-5515561 A is an M-type star, a small, cool red dwarf, with a spectral type of M5.5/M6. It is a very young star, with an age of 0.03 billion years, and it has a mass of 0.19 solar masses, a reported mass estimate smaller than the Sun's. One planet orbits this host.

That planet is 2MASS J01033563-5515561 AB b, discovered by imaging in 2013. It is a circumbinary planet, meaning it orbits both stars of the binary system rather than one star alone. 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 2MASS J01033563-5515561 AB b.
