Geothermal gradient is the rate of change in temperature with respect to increasing depth in Earth 's interior. As a general rule, the crust temperature rises with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 °C/km (72–87 °F/mi) of depth near the surface in ...
Differing in situ values have been reported for the average temperature on Mars, [23] with a common value being −63 °C (210 K; −81 °F). [24] [25] Surface temperatures may reach a high of about 20 °C (293 K; 68 °F) at noon, at the equator, and a low of about −153 °C (120 K; −243 °F) at the poles. [26]
Moon's internal structure. Olivine basalt collected by Apollo 15. Thermal state of the Moon at age 100 Ma. [ 1] Having a mean density of 3,346.4 kg/m 3, [ 2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted from the fractional ...
"Meteorite impacts generate high temperatures ranging from 2,000-6,000 degrees Celsius (3,600-10,800 degrees Fahrenheit). These extreme temperatures melt and vaporize rocks on the lunar surface ...
The lunar polar regions are home to craters that are in permanent shadow due to their orientation and depth, and can reach temperatures as low as -410 degrees Fahrenheit (-246 degrees Celsius).
Black-body radiation is the thermal electromagnetic radiation within, or surrounding, a body in thermodynamic equilibrium with its environment, emitted by a black body (an idealized opaque, non-reflective body). It has a specific, continuous spectrum of wavelengths, inversely related to intensity, that depend only on the body's temperature ...
Atmosphere of the Moon. The thin lunar atmosphere is visible on the Moon's surface at sunrise and sunset with the lunar horizon glow [ 1] and lunar twilight rays, like Earth's crepuscular rays. This Apollo 17 sketch depicts the glow and rays [ 2] among the general zodiacal light [ 3][ 4]. The atmosphere of the Moon is a very sparse layer of ...
Titania ( / təˈtɑːniə, təˈteɪniə / ), also designated Uranus III, is the largest of the moons of Uranus. At a diameter of 1,578 kilometres (981 mi) it is the eighth largest moon in the Solar System, with a surface area comparable to that of Australia. Discovered by William Herschel in 1787, it is named after the queen of the fairies in ...
