Some individuals and organizations offer schemes or plans claiming to allow people to purchase portions of the Moon or other celestial bodies. Though the details of some of the schemes' legal arguments vary, one goes so far as to state that although the Outer Space Treaty, which entered force in 1967, forbids countries from claiming celestial bodies, there is no such provision forbidding ...
During the warm late Eocene, sea levels were high, and the tidewater region of Virginia lay in the coastal shallows. The shore of eastern North America, about where Richmond, Virginia is today, was covered with thick tropical rainforest, and the waters of the gently sloping continental shelf were rich with marine life that was depositing dense layers of lime from their microscopic shells.
This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts. The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay .
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
This is a list of the projected landing zones on extraterrestrial bodies. The size of the ellipse or oval graphically represents statistical degrees of uncertainty, i.e. the confidence level of the landing point, with the center of the ellipse being calculated as the most likely given the plethora of variables.

Therefore there would be a discrepancy between the actual landings and the list of artificial objets; i.e. the list of artificial objects is semi-independent to the landings, as each landing mission can leave many or few objects on the surface, and all such manned missions brought peices of the landing equipment back with them.

The crash landing sites themselves are of interest to space archeology. Luna 1 , not itself a lunar orbiter, was the first spacecraft designed as an impactor . It failed to hit the Moon in 1959, however, thus inadvertently becoming the first man-made object to leave geocentric orbit and enter a heliocentric orbit , where it remains.
