[SysBP Img]

Star with a giant planet or Brown Dwarf (M betw 10-40MJ) which has been directly photographed. Reguardless of its nature, it is the first and coolest substellar companion to a sunlike star ever photographed (333 C, about as hot as Mercury). It orbits at about Neptune's distance and is still in the contraction phase. A possible third companion may have been imaged, later observations should determine if it is bound to the system or merely an object in the background.
