P/2016 G1

P/2016 G1 (PANSTARRS) was an asteroid that astronomers believe disintegrated in 2016. When observed, on April 1, 2016, discoverers Robert Weryk and thought the object was an Encke-type comet, and the object was subsequently designated P/2016 G1. After further analysis what had initially appeared to be a comet's halo turned out to be rubble from a collision. By November, 2019, analysis suggested the collision had occurred on March 6, 2016, and the asteroid was struck by a smaller object that may have massed only 1 kilogram (2.2 lb), and was traveling at 11,000 miles per hour (18,000 km/h). P/2016 G1's diameter was between 200 metres (660 ft) and 400 metres (1,300 ft).
