The story
Gonggong is a scattered-disc object found by Brown, Schaller and Trujillo in 2007, named after the Chinese water god. Its orbit takes 552 years, swinging from 34 to 101 AU from the Sun. It has a moon, Xiangliu.
Its red colour comes from methanol and other organics darkened by radiation; water ice and methane are likely on the surface. JWST is studying its surface chemistry.
