1362 Griqua, provisional designation 1935 QG1 is a dark, Jupiter-resonant background asteroid on an eccentric, cometary-like orbit and the namesake of the Griqua group, located in the Hecuba gap in the outermost region of the asteroid belt.[5] The carbonaceous asteroid measures approximately 28 kilometers (17 miles) in diameter and has a rotation period of 6.9 hours.[4] It was discovered on 31 July 1935, by South-African astronomer Cyril Jackson at Union Observatory in Johannesburg.[1] The asteroid was named after the Griqua people in South Africa and Namibia.[2]
