The moon takes just under 27 days 8 hours to orbit the Earth once.
lunar orbit
For a period of time it stayed in lunar orbit, however, that orbit eventually decayed and the ascent stage crashed onto the moon.

The total time in space was just over 8 days and 3 hours. Just under 22 hours of that was spent on the lunar surface, with Armstrong and Aldrin spending a little over 2.5 hours walking around outside the LM.
24 men have orbited or flown past the moon. 12 men have landed on the surface of the moon.

The concept of Lunar Orbit Rendezvous (LOR) was proposed by John Houbolt, an engineer at NASA, as an approach to landing on the Moon during the Apollo program. This methodology involved separating the spacecraft into two parts, with one staying in lunar orbit while the other descended to the surface and then returned to dock in lunar orbit for the journey back to Earth.
The Apollo Lunar Module was developed in the 1960s as part of the Apollo program by NASA, with the first successful manned landing on the moon occurring on July 20, 1969. The Lunar Module played a crucial role in transporting astronauts from lunar orbit to the moon's surface and back to the command module in orbit.
Lunar module is the landing craft design to transport astronaut from Moon's orbit down to surface and return astronaut back to orbit. Lunar module is the key part in Apollo project led by NASA.
The side of the orbit of the moon that is closest to the Earth is the lunar perigee.
