  2. Lunar theory - Wikipedia

    en.wikipedia.org/wiki/Lunar_theory

    Lunar theory attempts to account for the motions of the Moon. There are many small variations (or perturbations ) in the Moon's motion, and many attempts have been made to account for them. After centuries of being problematic, lunar motion can now be modeled to a very high degree of accuracy (see section Modern developments ).

  3. Origin of the Moon - Wikipedia

    en.wikipedia.org/wiki/Origin_of_the_Moon

    The Moon's heavily cratered far-side. The origin of the Moon is usually explained by a Mars-sized body striking the Earth, creating a debris ring that eventually collected into a single natural satellite, the Moon, but there are a number of variations on this giant-impact hypothesis, as well as alternative explanations, and research continues into how the Moon came to be formed.

  4. Geology of the Moon - Wikipedia

    en.wikipedia.org/wiki/Geology_of_the_Moon

    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 ...

    Indian mathematician-astronomer Bhāskara II, in his Siddhanta Shiromani, calculates the longitudes and latitudes of the planets, lunar and solar eclipses, risings and settings, the Moon's lunar crescent, syzygies, and conjunctions of the planets with each other and with the fixed stars, and explains the three problems of diurnal rotation.

    The historic Chandrayaan-3 mission, which made India the fourth country to land on the moon one year ago Friday, has uncovered new evidence that supports a theory about early lunar history.

    The Babylonians were the first civilization known to possess a functional theory of the planets. [9] The oldest surviving planetary astronomical text is the Babylonian Venus tablet of Ammisaduqa, a 7th-century BC copy of a list of observations of the motions of the planet Venus that probably dates as early as the second millennium BC.

    Sunlight reflects off objects on the moon the same way it does here on Earth. So all of these images and videos include light reflecting from Earth, the lunar module, and from the dust on the surface.

    The Moon has free physical librations that require one or more stimulating mechanisms. [45] Tidal dissipation in the Moon depends on tidal frequency. [42] The Moon probably has a liquid core of about 20% of the Moon's radius. [11] The radius of the lunar core-mantle boundary is determined as 381 ± 12 km. [46]
