	Eudoxus (Lunar crater) - Wikipedia, the free encyclopedia
		Eudoxus is a prominent lunar impact crater that lies to the east of the northern tip of the Montes Caucasus range.
		It is located to the south of the prominent Aristoteles crater in the northern regions of the visible Moon.
		To the south is the ruined formation of Alexander crater, and the small LamÃ¨ch crater lies to the southwest.

		Following Gene Shoemaker's analysis in the late 1950s we now know that crater rays are pulverized ejecta widely dispersed from craters formed by high speed impact and mixed with local material gardened by such ejecta.
		The two most important recent studies are The Origin of Lunar Crater Rays by Hawke and colleagues, and Optical Maturity of Ejecta from Large Rayed Lunar Craters by Grier and colleagues.
		Although there are obviously many rayed craters, lists of crater ray systems are not as common as they were 100 years ago.

	Eudoxus - Hutchinson encyclopedia article about Eudoxus
		Probably Eudoxus regarded the celestial spheres as a mathematical device for ease of computation rather than as physically real, but the idea was taken up by Aristotle and became entrenched in astronomical thought until the time of the 16th-century Danish astronomer Tycho Brahe.
		In mathematics, Eudoxus' early success was in the removal of many of the limitations imposed by Pythagoras on the theory of proportion.
		Eudoxus is said to have been the one who first fixed the length of the year as 365.25 days, and to have invented the sundial

		Eudoxus has a cluster of small hills, like the nest of a small, untidy bird.
		Glacies is a 19th century term for the often abruptly bounded mound that surrounds the crater like a fat tire on a bicycle rim.
		I speculate, getting back to the question of Eudoxus’ piddly peaks, that the crater’s formation on the thick layer of Imbrium ejecta debris caused the rebound energy that normally forms central peaks to be dissipated by the rubble.

		Lunar Sinuous Rilles Lowland areas on the near side of the moon are gouged with peculiar valleys, or clefts, now widely referred to as rilles.
		Water, outgassed from the lunar interior and trapped beneath a layer of permafrost, could be released by a meteoritic impact and overflow the crater to form an ice- covered river.
		From Baldwin's analysis of lunar and terrestrial explosion craters, it would appear that such a bolt ought to produce a lunar crater about 85 meter in diameter (see Figure 1.) Aristarchus, as indicated in the figure, was probably formed by an explosion, releasing some 2 X 1021 joules of energy.

		The crater Aristoteles and its smaller companion Eudoxus to the south ( Rukl chart 13) are "landmark" features, easily recognized and useful in orientation.
		There is no such fine detail around nearby Eudoxus, but there appears to be a semicircular ring of broken rubble and mountains linking the two craters (this may just be the tail of the Caucasus, but it looks like a separate feature.
		It's large, flat, and has a perfect "central crater" that caught the light in such a way as to have a pitch dark center and flaring rims.

	LPOD - Lunar Photo of the Day - June 18, 2004
		Aristoteles and Eudoxus are two of the largest young craters in the north polar region of the Moon.
		Because Eudoxus formed on rubbly Imbrium ejecta, its secondary craters are harder to recognize.
		Since both craters have about the same number of superposed (subsequent) impact craters, the two craters must be very near the Copernican-Eratosthenian boundary, with one slightly older and the other slightly younger.

		It's a very old crater, and as a "Class Five" is thought to have experienced different degrees of lava flooding, or perhaps filled with ashes, during its formation causing it to be more shallow than its original depth.
		The reason for this is that crater Proclus has an albedo, or surface reflectivity of about 16%, which is an unusually high value for a lunar feature.
		This particular crater is unusual in the sense that the floor is parabolic.

	Transient Lunar Phenomena
		"Transient Lunar Phenomena" (TLP) is a term used to describe anything which is seen on the moon which is not supposed to be there, and which contradicts the view that the surface of the moon is dead and unchanging.
		In 1843, Julius Schmidt, the director of the Athens observatory observed that the crater Linne, in the Mare Serenitatis (named after the pioneering taxonomist, Linnaeus) was several miles in diameter and entirely filled with shadow, when close to the terminator (the border between the illuminated and shadowed regions of the face of the moon).
		They also have detachable heads and eyes, are covered from head to foot in scales, grow on trees, have only one finger on each hand and go into battle riding three headed vultures, armed with giant asparagus spears, and mushrooms for shields.
