The Envisat satellite is a large, inactive satellite with a mass of 8,211 kg (18,102 lb) that orbits at 785 km (488 mi), an altitude where the debris environment is the greatest—two catalogued objects can be expected to pass within about 200 m (660 ft) of Envisat every year [40] —and likely to increase.
