The gravitational attraction that Earth and the Moon (as well as the Sun) exert on each other manifests in a slightly greater attraction on the sides closest to each other, resulting in tidal forces. Ocean tides are the most widely experienced result of this, but tidal forces also considerably affect other mechanics of Earth, as well as the Moon and their system.
On the evenings of November 29 and 30, 2023, the waning gibbous moon will pass Castor and Pollux, the twin stars of Gemini. They’ll rise a few hours after sunset and be visible traveling across the sky all night. Chart via EarthSky. November 30 morning: Venus and Spica conjunction The surface is exposed to drastic temperature differences ranging from 140°C to −171°C depending on the solar irradiance.
“Two the Moon” 2nd Birthday Party
While the giant-impact theory explains many lines of evidence, some questions are still unresolved, most of which involve the Moon's composition. [56] Models that have the Moon acquiring a significant amount of the proto-earth are more difficult to reconcile with geochemical data for the isotopes of zirconium, oxygen, silicon, and other elements. [57] Above a high resolution threshold for simulations, [ clarify] a study published in 2022 finds that giant impacts can immediately place a satellite with similar mass and iron content to the Moon into orbit far outside Earth's Roche limit. Even satellites that initially pass within the Roche limit can reliably and predictably survive, by being partially stripped and then torqued onto wider, stable orbits.

They're not called earthquakes but moonquakes. They are caused by the gravitational influence of the Earth. Unlike quakes on Earth that last only a few minutes at most, moonquakes can last up to half an hour. They are much weaker than earthquakes though. 10. There is water on the Moon! If the Earth were a water world (one with no continents) it would produce a tide of only one meter, and that tide would be very predictable, but the ocean tides are greatly modified by other effects: November 27 and 28, 2023, the bright waning gibbous moon will lie near a trio of bright stars. It’ll be near the fiery orange star Aldebaran of Taurus the Bull and Orion’s mighty red supergiant star Betelgeuse. The bright golden star is Capella of the constellation Auriga the Charioteer. You can follow them until sunrise. Chart via EarthSky.

Schmitt next to a large Moon boulderAt the North and South Poles the Moon is 24 hours above the horizon for two weeks every tropical month (about 27.3 days), comparable to the polar day of the tropical year. Zooplankton in the Arctic use moonlight when the Sun is below the horizon for months on end. [185] The main features visible from Earth by the naked eye are dark and relatively featureless lunar plains called maria (singular mare; Latin for "seas", as they were once believed to be filled with water) [119] are vast solidified pools of ancient basaltic lava. Although similar to terrestrial basalts, lunar basalts have more iron and no minerals altered by water. [120] The majority of these lava deposits erupted or flowed into the depressions associated with impact basins. Several geologic provinces containing shield volcanoes and volcanic domes are found within the near side "maria". [121] The thin waning crescent moon will move away from dazzling Venus and will pass the moderately bright star Zubenelgenubi in Libra the Scales on the morning of December 10. An even thinner crescent moon will hang near the horizon shortly before sunrise on the morning of December 11. Can you see a delicate glow on the unlit portion of the crescent moon? That’s earthshine! It’s reflected light from the Earth. Chart via EarthSky. December 12: New moon The English adjective pertaining to the Moon is "lunar", derived from the Latin word for the Moon, lūna. Selenian / s ə l iː n i ə n/ [28] is an adjective used to describe the Moon as a world, rather than as a celestial object, [29] but its use is rare. It is derived from σελήνη selēnē, the Greek word for the Moon, and its cognate selenic was originally a rare synonym [30] but now nearly always refers to the chemical element selenium. [31] The element name selenium and the prefix seleno- (as in selenography, the study of the physical features of the Moon) come from this Greek word. [32] [33]
On the final morning of the month, November 30, 2023, Venus will reach its closest approach – or will have a close conjunction– to the star Spica. Spica is the brightest star in Virgo the Maiden. They’ll be a little over 4 degrees apart on the sky’s dome, or roughly the width of 8 full moons lined up side-by-side. Chart via EarthSky. December 1 morning: Moon near Castor, Pollux and Procyon Here are some of the Two The Moon party decorations I ended up using for this second birthday party. Outer Space Felt BoardIf the two bodies had come from the same place and were made of similar stuff to begin with, this would also explain how similar their composition is.' The surface of the Moon On 1 November 2023, scientists reported that, according to computer simulations, remnants of a protoplanet, named Theia, could be inside the Earth, left over from a collision with the Earth in ancient times, and afterwards becoming the Moon.
