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 Moon then wanes as it passes through the gibbous moon, third-quarter moon, and crescent moon phases, before returning back to new moon. The terms old moon and new moon are not interchangeable. The "old moon" is a waning sliver (which eventually becomes undetectable to the naked eye) until the moment it aligns with the Sun and begins to wax ...

The mini-moon will be small — 33 feet long — and dim. NASA uses magnitude to describe brightness in space. A 6.5 magnitude is generally the dimmest object the human eye can see. The mini-moon ...
The "harvest moon" (also known as the "barley moon" or "full corn moon") is the full moon nearest to the autumnal equinox (22 or 23 September), occurring anytime within two weeks before or after that date. [18] The "hunter's moon" is the full moon following it. The names are recorded from the early 18th century. [19]
Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
Moon landing deniers say there's clear photographic evidence of this, and point out that because there's no breeze on the moon, this must be fake. Apollo 11astronaut Edwin Buzz Aldrin, on the Moon ...
The far side of the Moon was first photographed on October 7, 1959, by the Soviet probe Luna 3. Though vague by today's standards, the photos showed that the far side of the Moon almost completely lacked maria. The first American probe to fly by the Moon was Pioneer 4 on March 4, 1959, which occurred shortly after Luna 1. It was the only ...
