In contrast, the Lunar distance (LD or ), or Earth–Moon characteristic distance, is a unit of measure in astronomy. More technically, it is the semi-major axis of the geocentric lunar orbit . The lunar distance is on average approximately 385,000 km (239,000 mi), or 1.28 light-seconds ; this is roughly 30 times Earth's diameter or 9.5 times ...
Moon's orbit and sizes of Earth and Moon to scale. ... (0.87 in) per year (2200 km or 0.56% or the Earth-moon distance per hundred million years) ...
The Moon is Earth's only natural satellite. It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth.
The percentage columns show the distance from the orbit compared to the semimajor axis. E.g. for the Moon, L 1 is 326 400 km from Earth's center, which is 84.9% of the Earth–Moon distance or 15.1% "in front of" (Earthwards from) the Moon; L 2 is located 448 900 km from Earth's center, which is 116.8% of the Earth–Moon distance or 16.8% ...

Dubbed the 2024 PT5, the 'mini-moon' will orbit Earth for nearly two months. It comes in a season of lunar phenomena. What you need to know about Earth's new, temporary mini-moon
Measuring just 33 feet across, the asteroid will follow a horseshoe-like path around the Earth and will be a mini-moon from Sept. 29 until Nov. 25, according to a study published by the.
In order to be considered a "mini-moon," an incoming object must reach Earth at a range around 2.8 million miles and at a steady space of about 2,200 mph, according to Marcos.
