	Impact crater - Wikivisual
		An impact crater (impact basin, astrobleme or sometimes crater) is a circular or oval depression on a surface, usually referring to a planet, moon, asteroid, or other celestial body, caused by a collision of a smaller body (meteor) with the surface.
		Few underwater craters have been discovered because of the difficulty of surveying the sea floor; the rapid rate of change of the ocean bottom; and the subduction of the ocean floor into the Earth's interior by processes of plate tectonics.
		The distinctive mark of an impact crater is the presence of rock that has undergone shock-metamorphic effects, such as shatter cones, melted rocks, and crystal deformations.

		An impact crater (impact basin or sometimes crater) is a circular depression on a surface, usually referring to a planet, moon, asteroid, or other celestial body, caused by a collision of a smaller body (meteorite) with the surface.
		In the center of craters on Earth a crater lake often accumulates, and a central island or peak (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake.

		A crater (basin or impact crater) is a circular depression on a surface, usually referring to a planet, moon, asteroid, or other celestial body.
		Craters are caused by meteorite impacts or electrical discharge, although some are caused by volcanic activity (see volcano for more details), or karstic erosion (see Karst Crater for more details).
		In the center of craters on Earth a crater lake often accumulates, and in craters formed by meteorites a central island (caused by rebounding crustal rock after the impact) is usually a prominent feature in the lake.

	Triton (moon)
		Triton is unique among all large moons in the solar system for its retrograde orbit around the planet (i.e., it orbits in a direction opposite to the planet's rotation).
		Triton's axis of rotation is also unusual, tilted 157 degrees with respect to Neptune's axis, which is in turn inclined 30 degrees from the plane of Neptune's orbit.
		Surprisingly, however, Triton is geologically active; its surface is fresh and sparsely cratered, and the Voyager 2 probe observed numerous volcanoes erupting liquid nitrogen, dust, or methane compounds from beneath the surface in plumes up to 8 km high.

		Daniel_Barringer (1860-1929) was one of the first to identify a geological structure as an impact crater, the Barringer Meteorite Crater (or the "Meteor Crater") in Arizona, but at the time his ideas were not widely accepted, and when they were, there was no recognition of the fact that Earth impacts are common in geological terms.
		The Barringer_crater in Arizona is a perfect example of a simple crater, a straightforward bowl in the ground.

		In mythology, Triton was a sea god with the head and upper body of a man and the tail of a fish.
		The moon Triton is similarly "made in two parts." The orbit of Triton is currently circular, but it probably was not so early on.
		Triton was captured by collision with a primordial regular moon of Neptune several billion years ago.

		The age of known impact craters on the Earth ranges from a few thousand to almost two billion years, though few older than 200 million years have been found as geological processes tend to obliterate older ones.
		Few underwater craters have been discovered because of the difficulty of surveying the sea floor; the rapid rate of change of the ocean bottom; and the subduction of the ocean floor into the Earth's interior by processes of continental drift.
		In either case, the size of the crater depends on the material in the impact regions.

		The most essential part of a volcano is the crater, a hollow[?] basin, generally of a circular form.
		Some volcanoes consist of a crater alone, with scarcely any mountain at all; but in the majority of cases the crater is situated on the top of a mountain, which in some instances towers to an enormous height.
		The part of the mountain which terminates in the principal crater is usually of a conical form -- much like a glass-house chimney, and is therefore named the cone.

		There are very few craters on Europa (only three are larger than 5 km in diameter), and its albedo is one of the highest of all moons.
		The temperature on the surface of Europa is 110 K at the equator and only 50 K at the poles, however, so the surface water ice is as hard as rock.
		The largest craters appear to be filled with flat, fresh ice; based on this and on the calculated amount of heat generated by Europan tides it is predicted that the outer crust of solid ice is approximately 10-30 kilometres thick, which could mean that the liquid ocean underneath may be as deep as 90 kilometres.

		This would seem to indicate a young and active surface; based on estimates of the frequency of cometary bombardment Europa probably endures, Europa's surface must be no more than 30 million years old.

		In addition, it orbits Neptune in a backward direction called "retrograde," and may eventually spiral close enough to Neptune to be torn apart by the planet's gravity.
		Most moons have craters, which show that our early solar system was a crowded place with objects crashing into one another.
		The smaller object in the crash is usually destroyed, but the larger object is often left with a crater.

		Triton's surface age and impactor population revisited in light of Kuiper Belt fluxes: Evidence for small Kuiper Belt objects and recent geological activity
		We find that the population of impactors creating the smallest observed craters on Triton must be sub-km in scale, and that this small-impactor population can be best fit by a differential power-law size index near -3.
		The subtle upward curvature in the impactor size vs. crater size is due to the diameter correction for complex craters given in Equation (2b).

		Chicxulub crater in the northern Yucatan of Mexico has a diameter of 170 km, but some researchers believe the full dimension of the hidden crater is 300 km in diameter.
		The existence of a string of three impact craters 12 kilometers wide in Chad was announced by a NASA Jet Propulsion Laboratory scientist and her colleague in March 1996.
		Tables comparing crater diameters with their frequency of occurrence on Earth and average time intervals of occurrence indicate that 150 km diameter craters occur every 100 million years, 100 km craters every 50 million years, 50 km craters every 6 million years, and 10 km craters every 10,000 years.

	LUNAR ASTROTOPONIMY
		Astrotoponimy(from the Greek topos=place and nomos=name) is the art of interpreting the meaning of the names of places in a planet's surface...for instance, craters, valleys, ridges, continents.
		The surface of the Moon has several features such as craters, valleys, mountains, etc., that are also found in other planets and satellites of the solar system.But the fact that makes the Moon unique among other celestial bodies are its lava plains called Maria (singular:mare, sea), Oceanus (ocean), Sinus (bays), and Palus (marshes).
		Of course, they don't have any water like those on earth, but they are named after these watery sources because of their appeareance from the Earth's surface.

		Although we did not get as good a view of Triton as we did of the moons of Saturn or Jupiter, the pictures that the world has received have shown that the surfaces of the ice worlds of the outer solar system cannot be pigeonholed and categorized, but studied as subjects in their own right.
		Ganymede is cratered as well, but it shows much evidence of internal activity -- the large, light colored upwellings that cover the moon.
		Europa is perhaps one of the few worlds without craters; instead, its molten (read fluid H$_{2$O) interior erases evidence of cratering by periodic fissure eruptions from the numerous linear features.

		Triton is the seventh, and largest (with a diameter of 2,700 km), moon of Neptune.
		It has a retrograde orbit which causes tidal interactions between it and Neptune resulting in it having a lower orbit because of a loss of energy.
		The surface of Triton is relatively young, therefore it has few visible craters, yet there are ice volcanoes.
