    Orbit


    The planet takes 3416 days to revolve at an orbital distance of 3.4 AU; this is the longest-period Jupiter-like planet orbiting a red dwarf.[2] The brightness of the faint parent star at that distance corresponds to the brightness of the Sun from 80 AU (or a 100 times brighter than a full Moon as seen from Earth).


    Discovery


    The planet was discovered in the Anglo-Australian Observatory on September 1, 2008.
