List of heaviest spacecraft
List of heaviest spacecraft, is a listing of selected examples of spacecraft by mass. Spacecraft may change mass over time such as by loss of coolant. The heaviest artificial things include the space stations, various upper stages, and discarded Space Shuttle external tanks.
