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. The brightness of the faint parent star at that distance corresponds to the brightness of the Sun from 80AU (or a 100 times brighter than a full Moon as seen from Earth).
