    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.

    gollark: You should believe me when I say things now because I can obviously guess well.
    gollark: I SAID it was obviously citrons, but none of you believed me because you're apio4ms.
    gollark: I'd seen citrons say that sort of thing, and coupled with the APIARIES, my knowledge of their socket programming knowledge in blattidus, and their programming style, it was obviously citronic.
    gollark: Next time I should have GPT-3 generate comments for me.
    gollark: baidicoot talks about continuation passing style a lot and it seemed applicable since my interpreter can tail recurse.
