    It’s also over 7500 AU (or, over 697,500,000,000 miles) away from its host star. Meaning it’s over 7500x further from its star than we are from ours. I suppose it makes sense that it’d take that long to complete an orbit!

      It does basically look stationary, but if you know the masses of the planet and the star and know the radius of orbit, then you can determine what the speed must be for it to be a stable orbit.

    I wonder how life would evolve on a planet like that. Could evolution account for things like seasons that last hundreds of thousands of years? Or would entire species rise and fall between each and every ice age?

      Did you see the orbit semi major axis? That gas gaint is so far away from the star it’s probably orbit even outside host star’s heliosphere. For reference, pluto’s semi major is 39.48AU, and this coconuts-2b is 7506AU.

      The star is about one-third the mass of the Sun,

      So forget anything like receiving enough energy from sun to have any chemical reaction going. It would be too cold for anything organic.(in our standard to even jitter around.)

        Well yeah, I didn’t mean that planet specifically. Just one that took a million years to orbit their star. I’m sure there are probably more out there in the same situation,maybe even with a larger sun and in the goldilocks zone and not a gas giant.

          yeah, in that sense those creature would be more like plants? since their time flow would be much much slower than our zapping around planet. They would probably look dead to us and we wouldn’t know since would probably take 100 earth year to say “ah” in their normal speed. lol

        39AU, that puts it in perspective. I imagine the gas giant generates more heat than it receives from the sun.
