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 ...
With a mean orbital velocity around the barycentre between the Earth and the Moon, of 1.022 km/s (0.635 miles/s, 2,286 miles/h), [6] the Moon covers a distance approximately its diameter, or about half a degree on the celestial sphere, each hour.
Orion took the snapshot around its maximum distance from Earth of 268,563 miles. That's the farthest any human-oriented spacecraft has traveled, beating even Apollo 13's record of 248,655 miles ...
The Moon is Earth's only natural satellite.It orbits around Earth at an average distance of 384,400 km (238,900 mi), about 30 times the width of Earth. The Moon faces Earth always with the same side, because tidal forces between Earth and the Moon have synchronized the Moon's rotation period with its orbital period (lunar month) at 29.5 Earth days.

Although the Moon's Hill sphere extends to a radius of 60,000 km (37,000 mi), [6] the gravity of Earth intervenes enough to make lunar orbits unstable at a distance of 690 km (430 mi). [7] The Lagrange points of the Earth-Moon system can provide stable orbits in the lunar vicinity, such as halo orbits and distant retrograde orbits.
The buck moon will rise on Monday, July 3. It will be the first supermoon of the year, appearing brighter and slightly bigger than any other full moon in 2023 so far.
