This has made it possible to measure, say, the distance to the Moon with sub-centimeter accuracy ( see Lunar laser ranging experiment ), to measure slight movement of tectonic plates using GPS with sub-millimeter accuracy, or even to measure as slight variations in the distance between two mirrors separated by several kilometers as 10 < sup >− 18 </ sup > m — three orders of magnitude less than the size of a single atomic nucleus — see LIGO.

* UT0 is Universal Time determined at an observatory by observing the diurnal motion of stars or extragalactic radio sources, and also from ranging observations of the Moon and artificial Earth satellites.

Hence, it is computed from observations of distant quasars using long baseline interferometry, laser ranging of the Moon and artificial satellites, as well as the determination of GPS satellite orbits.

Subsequent measurement attempts arrived at values ranging from 2, 500 to 6, 000 km, or from slightly smaller than our Moon to nearly half the diameter of Earth.

The primary objectives of the mission were to collect images of the lunar surface, examine ambient light levels to determine the feasibility of astronomical observations from the Moon, perform laser ranging experiments from Earth, observe solar X-rays, measure local magnetic fields, and study mechanical properties of the lunar surface material.

The primary objectives of the mission were to collect images of the lunar surface, examine ambient light levels to determine the feasibility of astronomical observations from the Moon, perform laser ranging experiments from Earth, observe solar X-rays, measure local magnetic fields, and study the soil mechanics of the lunar surface material.

This drifting was later confirmed by American and Soviet experiments, using laser ranging targets placed on the Moon.

The ongoing Lunar Laser Ranging Experiment measures the distance between the Earth and the Moon using laser ranging.

By convention for the Earth, Moon, and Sun it is expressed as degrees ranging from − 180 ° to + 180 ° For other bodies a range of 0 ° to 360 ° is used.

For example, ranging in size from less than 100 micrometers to more than 250 micrometers, similar spherules were found in Moon soil samples collected by Apollo 12 at the Procellarum Basin, and Apollo 14 near Mare Imbrium ( Sea of Rains ), the dark crater that dominates the Moon's face, and their properties were consistent with expectations for creation by meteor impacts.

But for lunar ranging science, what is really wanted is the distance between the center of mass of the Earth and the center of mass of the Moon.
