(95626) 2002 GZ32 (provisional designation 2002 GZ32) is a centaur orbiting the Sun between Saturn and Neptune in the outer Solar System. It is one of the largest known centaurs, having a highly elongated shape that spans 366 km (227 mi) across its longest width to 120 km (75 mi) across its shortest. The object was discovered on 13 April 2002 by astronomers at Mauna Kea Observatory in Hawaiʻi.
Due to 2002 GZ32's highly elongated shape, its apparent brightness oscillates as it rotates every 5.8 hours. 2002 GZ32 has a dark gray surface that potentially contains water ice. It was the third centaur whose stellar occultation has been simultaneously observed by multiple people, after 10199 Chariklo and 2060 Chiron.
