2MASS J04414489+2301513
2MASS J04414489+2301513 (often abbreviated as 2M J044144) is a young star system hosting a planet and a couple of brown dwarfs, approximately 470 light years (145 parsecs) away. The 2MASS J04414489+2301513 primary (a brown dwarf) has a large separation (12.4 arcseconds) companion, 2MASS J04414565+2301580 (abbreviated as 2M J044145), which in turn has a nearby small separation substellar companion (separation of 0.23 arcseconds to the northeast). 2M J044145 has similar proper motion to 2M J044144 and is likely physically associated with the system. The entire system of 4 objects is then a hierarchical quadruple of two binary stars orbiting each other. The primary component has a spectral type of M4.5 and a red apparent magnitude of 14.2. Both components seem to be accreting mass from their
