Dodona (minor planet designation: 382 Dodona) is a large Main belt asteroid An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. ... that was discovered by the French astronomer Auguste Charlois on 29 January 1894 in Nice. It is classified as an M-type asteroid. Measurements of the thermal inertia of 115 Thyra give an estimated range of 15–150 J m−2 K−1 s−1/2, compared to 50 for lunar regolith and 400 for coarse sand in an atmosphere.

Auguste Charlois
Auguste Honoré Charlois (November 26, 1864 – March 26, 1910) was a French astronomer who discovered 99 asteroids while working at the Nice Observatory in southeastern France. Asteroid Discovery His first discovery was the asteroid 267 Tirza in 1887. He photographed 433 Eros on the very night of its discovery by Gustav Witt, but was not able to act quickly enough before Witt announced his find. Although he started searching for asteroids in the era of visual detection, by 1891 Max Wolf had pioneered the use of astrophotography to drastically speed up the rate of detection of asteroids, and both Wolf and Charlois separately discovered far more asteroids than would have been feasible by visual detection. In 1899, Charlois received the Prix Jules Janssen, the highest award of the Société astronomique de France, the French astronomical society, and was also awarded the Valz Prize by the French Academy of Sciences in 1889 for his work on calculating asteroid orbits.

Minor Planet Designation
A formal minor-planet designation is, in its final form, a number–name combination given to a minor planet (asteroid, centaur, trans-Neptunian object and dwarf planet but not comet). Such designation always features a leading number (catalog or IAU number) assigned to a body once its orbital path is sufficiently secured (so-called "numbering"). The formal designation is based on the minor planet's provisional designation, which was previously assigned automatically when it had been observed for the first time. Later on, the provisional part of the formal designation may be replaced with a name (so-called "naming"). Both formal and provisional designations are overseen by the Minor Planet Center (MPC), a branch of the International Astronomical Union. Currently, a number is assigned only after the orbit has been secured by four well-observed oppositions. For unusual objects, such as near-Earth asteroids, numbering might already occur after three, maybe even only two, oppositio ...

Lunar Regolith
Lunar soil is the fine fraction of the regolith found on the surface of the Moon. Its properties can differ significantly from those of terrestrial soil. The physical properties of lunar soil are primarily the result of mechanical disintegration of basaltic and anorthositic rock, caused by continual meteoric impacts and bombardment by solar and interstellar charged atomic particles over billions of years. The process is largely one of mechanical weathering in which the particles are ground to progressively finer size over time. This situation contrasts fundamentally to terrestrial dirt formation, mediated by the presence of molecular oxygen (O2), humidity, atmospheric wind, and a robust array of contributing biological processes. ''Lunar soil'' typically refers to only the finer fraction of lunar regolith, which is composed of grains 1 cm in diameter or less, but is often used interchangeably. Lunar dust generally connotes even finer materials than ''lunar soil''. There is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Inertia
In thermodynamics, a material's thermal effusivity, thermal inertia or thermal responsivity is a measure of its ability to exchange thermal energy with its surroundings. It is defined as the square root of the product of the material's thermal conductivity (\lambda) and its volumetric heat capacity (\rho c_p). :e = \sqrt The SI units for thermal effusivity are \sqrt / (), or, equivalently, / ( \sqrt). Thermal effusivity is a parameter that emerges upon applying solutions of the heat equation to heat flow through a thin surface-like region. It becomes particularly useful when the region is selected adjacent to a material's actual surface. Knowing the effusivity and equilibrium temperature of each of two material bodies then enables an estimate of their interface temperature T_m when placed into thermal contact. :T_m = \frac Specialty sensors have also been developed based on this relationship to measure effusivity. Thermal effusivity and thermal diffusivity are related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asteroid
An asteroid is a minor planet of the Solar System#Inner solar system, inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 astronomical unit, AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type asteroid, C-type, M-type asteroid, M-type, and S-type asteroid, S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres (dwarf planet), Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slig ...

Dodona
Dodona (; Doric Greek: Δωδώνα, ''Dōdṓnā'', Ionic and Attic Greek: Δωδώνη, ''Dōdṓnē'') in Epirus in northwestern Greece was the oldest Hellenic oracle, possibly dating to the second millennium BCE according to Herodotus. The earliest accounts in Homer describe Dodona as an oracle of Zeus. Situated in a remote region away from the main Greek poleis, it was considered second only to the Oracle of Delphi in prestige. Aristotle considered the region around Dodona to have been part of Hellas and the region where the Hellenes originated.; Aristotle. ''Meteorologica''1.14 The oracle was first under the control of the Thesprotians before it passed into the hands of the Molossians. It remained an important religious sanctuary until the rise of Christianity during the Late Roman era. Description During classical antiquity, according to various accounts, priestesses and priests in the sacred grove interpreted the rustling of the oak (or beech) leaves to determin ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown m ...
