[18] [19] [20] Saturn's biggest moon. [21] Although Rhea is the ninth-largest moon, it is only the tenth-most massive moon. Indeed, Oberon, the second-largest moon of Uranus, has almost the same size, but is significantly denser than Rhea (1.63 vs 1.24) and thus more massive, although Rhea is slightly larger by volume.
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.
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius.
c. 1990 — The Clementine topographic data use 1,737,400 meters as the baseline, and show a range of about 18,100 meters from lowest to highest point on the Moon. This is not a list of the highest places on the Moon, meaning those farthest from the CoM. Rather, it is a list of peaks at various heights relative to the relevant datum.
In the 2019 film Ad Astra, the Moon base is situated in the Tycho crater. This is Roy's first stop on his journey to Mars. This is Roy's first stop on his journey to Mars. Crater Tycho figures prominently in the Matthew Looney and Maria Looney series of children's books set on the Moon, authored by Jerome Beatty .
The 842 pounds (382 kilograms) of lunar rocks and soil returned to Earth by the Apollo missions in the late 1960s and early 1970s disproved ideas that the moon was a celestial body caught in Earth ...
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 ...
According to David H. Levy, Shoemaker "saw the craters on the Moon as logical impact sites that were formed not gradually, in eons, but explosively, in seconds."
