[1] [2] [3] According to astronauts Eugene Cernan and Ed Lu, the Great Wall is visible from the lower part of low Earth orbit, but only under very favorable ...
The term artificial objects is closely associated with made by humans or not naturally occurring items that have been sent into space.

The camera (near Conrad's right hand) is on display at the National Air and Space Museum. Third-party evidence for Apollo Moon landings is evidence, or analysis of evidence, about the Moon landings that does not come from either NASA or the U.S. government (the first party), or the Apollo Moon landing hoax theorists (the second party).
Objects at greater than 90 degrees east or west are on the far side of the Moon, including Ranger 4, Lunar Orbiter 1, Lunar Orbiter 2, Lunar Orbiter 3, Chang'e 4 lander and Yutu-2 rover. Because of increasing numbers of missions to and objects at the Moon, a global registry of lunar activities has been proposed in 2023 by the Open Lunar Foundation.
Vanguard 1. Expected to de-orbit in ~2240AD, this and its upper launch stage are the oldest human-made objects in space. Also the first use of solar cells to power a satellite.

Three of the probes, Voyager 1, Voyager 2, and New Horizons are still functioning and are regularly contacted by radio communication, while Pioneer 10 and Pioneer 11 are now defunct. In addition to these spacecraft, some upper stages and de-spin weights are leaving the Solar System, assuming they continue on their trajectories.
Although most are defunct after having served their purpose, the Curiosity and Perseverance rovers are active. China's Tianwen-1 spacecraft is the most recent artificial object to land safely on Mars. The table does not include smaller objects, such as springs, fragments, parachutes and heat shields. As of February 2021, there are 14 missions ...
In the SVG file, hover over a trajectory or orbit to highlight it and its associated launches and flybys. Voyager 1 is a space probe launched by NASA on September 5, 1977, as part of the Voyager program to study the outer Solar System and the interstellar space beyond the Sun's heliosphere.
