      Are you talking about exoplanets, or the “just admit that every round solid object in space is a planet and there are a lot more than nine in the solar system” planets?

        Pluto is here, so minor planets count. That leaves at least Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna, Ceres, Orcus, and Salacia as vacation candidates.

        There are 19 more planetary-mass moons to consider as well, if orbital designation isn’t important to your stay. (I’d say it’s a bonus, as you can see some sick eclipses.)

          I want to know more about gonggong

          Is it pretty? Would I freeze or boil if I visited? What souvenirs should I bring back? Do I need to take my own water and oxygen or can I buy it there? How much fuel would I need to use if I wanted to push it into a more temperate orbit?

            Gonggong is named after a Chinese water god, and it does indeed have it’s own ice. It’s also red, covered in thiolins like Pluto, but even moreso. There’s also likely a thin methane exosphere, leaving methane frost on windows.

            Gonggong is very far out, moving between 33 and 101 AU over it’s 554 year orbit. It orbits at a 30° inclination, so telescopes would pick up some interesting shots of the other planets poles.

            The 1/30 g gravity is nothing special, plenty to jump around in, but enough to not fly away easily. It’s slightly flattened by it’s rotation, which is a nice 22 hours, much slower than other trans-neptunian bodies. This slow rotation is caused by tidal forces between it and it’s moon Xiangilu.

            Xiangilu is named for Gonggong’s minister, a nine headed venomous snake monster. It orbits every 25 days, nearly exactly a month like Earth’s moon, but in an eccentric orbit, changing size throut the month. Gonggong has a polar orientation like Uranus as well, leaving Xiangilu a constant half-moon in the dim sky half the year. Sadly eclipses would be very rare.

            The trip out there is rather long, but once there it seems quite unique and cozy.
