Comet West–Hartley is a periodic comet with a 7.67-year orbit around the Sun.
Physical characteristics
The first attempts to measure the effective radius of its nucleus in 2000 were not successful due to too much scatter data in light curves obtained to provide reliable estimates. Recent attempts to measure the comet's light curves between 2004 and 2015 revealed that the nucleus is about 2.18 km (1.35 mi) in radius, rotating once every 3.7 hours.
