What is the shape of the Linne crater?
inverted truncated-cone
Linné is a simple crater, with a diameter of 2.23 km and a depth of 0.52 km, located in northwestern Mare Serenitatis. Recent high-resolution data acquired by the Lunar Reconnaissance Orbiter Camera revealed that the shape of this impact structure is best described by an inverted truncated-cone.
What is a ghost crater on the Moon?
A ghost crater is a crater buried in lava, with only the crater rim visible. After that, during the time of active volcanism on the Moon, lava eruptions in the area may fill the crater to the brim, leaving behind just the rim. Many such ghost craters have been spotted on the Moon.
What does a crater look like on the Moon?
Simple craters like Moltke (which is 6.5 km in diameter and 1.3 km deep), have a smooth bowl-like shape with smooth walls. Most small craters less than about 15 km in diameter are simple craters. Complex craters like Tycho (which is 85 km in diameter and 4.5 km deep), have well defined crater rims and a central peak.
What craters are visible on the moon?
Locations and diameters of some prominent craters on the near side of the Moon:
- Albategnius (131 km)
- Aristarchus (40 km)
- Aristoteles (88 km)
- Bailly (301 km)
- Clavius (231 km)
- Copernicus (96 km)
- Fra Mauro (97 km)
- Humboldt (199 km)
Are craters parabolic?
Understanding the precise shapes of impact craters is therefore of considerable scientific interest. The existing shape model for small, simple craters is that they are approximately parabolic and have depths (d) of about one-fifth of their diameters (D) (Wilhelms et al.
How was the Linne crater formed?
Linné crater formed in a thick deposit of mare basalt. Typically young craters in mare have large numbers of boulders strewn around their outside flanks.
How were the Rilles on the lunar surface formed?
A rille is a long and narrow valley on the Moon and appears to have been formed by subsidence or collapse of surface materials along a crustal fracture (Baldwin 1968), which could be ascribed to the thermal and mechanical erosion, construction, and volatiles between the basement surface and a surficial permafrost layer …
Does the Moon have craters?
Craters are the most common surface features on many solid planets and moons—Mercury and our Moon are covered with craters. This portion of the Moon is covered by numerous circular holes. These are impact craters, each of which was formed when an asteroid or comet collided with the Moon’s surface.
