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.
Bliss, originally titled Bucolic Green Hills, is the default wallpaper of Microsoft's Windows XP operating system. It is a photograph of a green rolling hills and daytime sky with cirrus clouds . Charles O'Rear , a former National Geographic photographer, took the photo in January 1998 near the Napa – Sonoma county line, California, after a ...
[26] This would represent the first direct measurement of water content on the surface of the moon, although that result has not been confirmed by other researchers. [27] Clementine Composite image of the Moon's south polar region, captured by NASA's Clementine probe over two lunar days. Permanently shadowed areas could harbour water ice.
be re-implanted into the regolith as a result of the Moon's gravity; escape the Moon entirely if the particle is moving at or above the lunar escape velocity of 2.38 km/s (1.48 mi/s), or 5,328 mph (8,575 km/h); be lost to space either by solar radiation pressure or, if the gases are ionized, by being swept away in the solar wind's magnetic field.
Moon Museum is a small ceramic wafer three-quarters by one-half inch (19 by 13 mm) in size, [1] containing artworks by six prominent artists from the late 1960s. The artists with works in the "museum" are Robert Rauschenberg , David Novros , John Chamberlain , Claes Oldenburg , Forrest Myers and Andy Warhol .
The Moon looks larger near distant buildings than nearby ones in this simulated skyline. The size of a viewed object can be measured objectively either as an angular size (the visual angle that it subtends at the eye, corresponding to the proportion of the visual field that it occupies), or as physical size (its real size measured in, say, meters).
"The Face" near the Moon's South Pole. The Face on Moon South Pole is a region on the Moon (81.9° south latitude and 39.27° east longitude) that was detected automatically in an image from the Lunar Reconnaissance Orbiter by a computer system using face recognition technologies, [1] as a result of a project that was part of the International Space App Challenge 2013 Tokyo.
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 ...
