The purpose of this project is to list all human-made objects that were sent in deep space, way beyond the Earth’s orbit. While most of them are now orbiting celestial bodies such as the Sun, the planets and the moons, some are permanently set on their surfaces. A few of them are on their way to leave the solar system.
Note that the Earth’s artificial satellites are not listed here, except those that were part of an interplanetary mission.
As of May 2022, over 4,500 objects have been identified, ranging from large probes to small pins and including spent injection stages, rovers, heat shields, parachutes, dust caps, weights, bolts, lanyards, hand tools, foam blocks, sample bags, etc.
