 probe which failed to escape low Earth orbit.

Beginning in 1962, the name Kosmos was given to Soviet spacecraft which remained in Earth orbit, regardless of whether that was their intended final destination. The designation of this mission as an intended planetary probe is based on evidence from Soviet and non-Soviet sources and historical documents. Typically Soviet planetary missions were initially put into an Earth parking orbit

A parking orbit is a temporary orbit used during the launch of a satellite or other space probe. A launch vehicle boosts into the parking orbit, then coasts for a while, then fires again to enter the final desired trajectory...

 as a launch platform with a rocket engine and attached probe. The probes were then launched toward their targets with an engine burn with a duration of roughly 4 minutes. If the engine misfired or the burn was not completed, the probes would be left in Earth orbit and given a Kosmos designation.

 (known as the Ashburton balls incident), and two pieces (presumably the payload and detached engine unit) went into a higher 210 x 9800 km orbit. It is thought that a malfunction resulted in an engine burn which did not achieve sufficient velocity for the Venus transfer and left the payload in this elliptical Earth orbit.

, in 1978.

Space law required that the space junk be returned to its national owner, but the Soviets denied knowledge or ownership of the satellite. Ownership therefore fell to the farmer upon whose property the satellite fell. Kosmos 482 was thoroughly analysed by New Zealand scientists which determined that they were Soviet in origin because of manufacturing marks and the high-tech welding of the titanium. The scientists concluded that they were probably gas pressure vessels of a kind used in the launching rocket for a satellite or space vehicle and had decayed in the atmosphere.
