Gonggong (minor-planet designation: 225088 Gonggong) is a dwarf planet and a member of the scattered disc beyond Neptune.It has a highly eccentric and inclined orbit during which it ranges from 34–101 astronomical units (5.1–15.1 billion kilometers; 3.2–9.4 billion miles) from the Sun.
Gonggong is known from the late Warring States period (before 221 BC). Gonggong appears in the ancient "Heavenly Questions" (Tianwen) poem of the Chu Ci, where he is blamed for knocking the Earth's axis off center, causing it to tilt to the southeast and the sky to tilt to the northwest. [2]

Gonggong and its moon Xiangliu, imaged in 2009 and 2010 with Hubble's Wide Field Camera 3 [10]. Following the March 2016 discovery that Gonggong was an unusually slow rotator, the possibility was raised that a satellite may have slowed it down via tidal forces. [3]
On the other hand, the surfaces of Sedna, Gonggong, and Quaoar have low abundances of CO and CO 2, similar to Pluto, Eris, and Makemake but in contrast to smaller bodies. This suggests that the threshold for dwarf planethood in the trans-Neptunian region is a diameter of ~900 km (thus including only Pluto, Eris, Haumea, Makemake, Gonggong ...
When Pluto's significance was changed to dwarf planet, mnemonics could no longer include the final "P".The first notable suggestion came from Kyle Sullivan of Lumberton, Mississippi, USA, whose mnemonic was published in the Jan. 2007 issue of Astronomy magazine: "My Violent Evil Monster Just Scared Us Nuts".

For instance, JPL/NASA called Gonggong a dwarf planet after observations in 2016, [61] and Simon Porter of the Southwest Research Institute spoke of "the big eight [TNO] dwarf planets" in 2018, referring to Pluto, Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna and Orcus. [62]
