List of heaviest spacecraft

During the Shuttle–Mir program between 1994 and 1998, the complex formed by the docking of a visiting Space Shuttle with Mir would temporarily make it heaviest artificial object in orbit with a combined mass of 250 tonnes (250 long tons; 280 short tons) in a 1995 configuration.

[1][2] Currently the heaviest spacecraft is the International Space Station, nearly double Shuttle-Mir's mass in orbit.

It began assembly with a first launch in 1998, however it only attained its full weight in the 2020s, due to its modular nature and gradual additions.

The following are a list of spacecraft with a mass greater than 8,000 kg (17,637 lb), or the top three to any other orbit including a planetary orbit, or the top three of a specific category of vehicle, or the heaviest vehicle from a specific nation.
