  • Interesting fact: The whirling cloud, a flat cloud hovering over the peak of an extinct volcano, Mount Jirinaj in Indonesia, affected by hot air rising from the crater, spins swiftly around and around.
    • n crater pl. crateres (krā˙-tē′ rēz). In classical antiquity, a large vessel or vase in which water was mixed with wine according to accepted formulas, and from which it was dipped out and served to the guests in the smaller pouring-vessels (oinochoe). The typical form of the crater is open and bell-like, with a foot, and a small handle placed very low on either side. Many beautiful Greek examples are preserved, especially in the red-figured pottery. Also written krater. Compare oxybaphon.
    • n crater In geology, the cup-shaped depression or cavity of a volcano, forming the orifice through which the erupted material finds its way to the surface, or has done so in former times if the volcano is at present extinct or dormant. Such a depression is usually surrounded by a pile of ashes and volcanic débris, which forms the cone. Some craters have a very regular form; others are broken down more or less on one side.
    • n crater Milit., a cavity formed by the explosion of a military mine.
    • n crater Any hollow made in the earth by subterranean forces.
    • n crater [capitalized] An ancient southern constellation south of Leo and Virgo. It is supposed to represent a vase with two handles and a base.
    • n crater In electricity, a hollow cavity formed in the positive carbon of an arclamp when continuous currents are used.

  • Interesting fact: The final resting-place for Dr. Eugene Shoemaker - the Moon. The famed U.S. Geological Survey astronomer, trained the Apollo astronauts about craters, but never made it into space. Mr. Shoemaker had wanted to be an astronaut but was rejected because of a medical problem. His ashes were placed on board the Lunar Prospector spacecraft before it was launched on January 6, 1998. NASA crashed the probe into a crater on the moon in an attempt to learn if there is water on the moon.

My soul looked down from a vague height with Death,

And fitted with great pocks and scabs of plaques.

In science:

Europa of Jupiter has a highly cratered surface, with up to 95% of the smaller ones being secondaries (Bierhas et al. 2005).
Astrophysics in 2006
If this preponderance of secondaries should prove to be true of Mars as well, it would affect estimates of the ages of various parts of the surface based on crater numbers.
Astrophysics in 2006
Moon craters have been impact features all of our lives (and most of its), but Van Frese (2006) suggests that back-side impacts could have triggered some front side volcanoes.
Astrophysics in 2006
Craters in the surface are probably not impact craters, but may result from mass-loss driven by sublimation.

Note the large tongue-shaped smooth region in the lower half of the nucleus (a ground-hugging flow on an ob ject whose escape velocity is ∼1 m s−1 ?) and the relative lack of large craters compared to Figure 2.

The numerous depressions in the surface of P/Wild 2 at first glance resemble impact craters, but closer examination suggests that they are more likely to be related to the outgassing phenomenon.
Icy Bodies in the New Solar System
While similar in size to P/Wild 2, this nucleus is less densely cratered and a large swath of the surface is occupied by a smooth, lobate flow-like feature.

Most of the camera-facing side of Hyperion in Figure 5 is occupied by an impact crater with ∼20 km deep walls: the kinetic energy of the pro jectile that formed this crater must surely have been comparable to the energy needed to disrupt the satellite.
