It was named after German-born British astronomer William Herschel.[1]. It is 139 kilometers in diameter, which is almost one-third of the diameter of the moon! The large crater in the left foreground is the 164 km diameter Ptolemaeus, centered at 9.3 S, 1.9 W. Herschel crater, 40 km in diameter, is at the right, centered … About a third the diameter of Mimas itself, Herschel crater gives the small moon an ominous appearance, especially for scifi fans of the Death Star battlestation of Star Wars fame. When it first was spotted in 1801, astronomers thought it was a planet orbiting between Mars and Jupiter. Annu. 154 km. The impact that formed Herschel must have nearly disrupted Mimas entirely; fractures can be seen on the opposite side of Mimas that may be due to the shock waves from the impact travelling through the moon’s body. Martian impact crater Herschel based on THEMIS Day IR.png 14,111 × 9,987; 14.92 MB. The crater Herschel, named in honour of Mimas’s discoverer, the 19th-century English astronomer William Herschel, is 130 km (80 miles) across, one-third the diameter of Mimas itself. The impact that formed Herschel must have nearly disrupted Mimas entirely. Its walls are approximately 5 km (3 mi) high,[3] parts of its floor are 10–12 km (6–7 mi) deep, and its central peak rises 6–8 km (3 1⁄2–5 mi) above the crater floor. To the right is the 164 km diameter crater Ptolemaeus. Herschel, the crater. NASA photo. It is roughly 590 miles (950 kilometers) in diameter. [5], The similarity between Mimas's appearance and the Death Star in Star Wars due to the large size of Herschel has often been noted, both in the press and in NASA/JPL press releases. Eponym. The rim of this crater has been heavily eroded, to the point where it is frequently described as … Sci. Rev. Volume. This image from NASA's Dawn spacecraft shows a close up of part of the rim around the crater Canuleia on the giant asteroid Vesta. The small crater Herschel G is attached to the south-southwest rim, and a tiny craterlet lies across the southern rim. Mare Tyrrhenum map.JPG 639 × 420; 57 KB. Its diameter is 39 km. 62°00′N 42°00′W /  62.0°N 42.0°W. Recent Galileo images indicate that the 25 km-diameter crater Cilix on Europa is also a classic complex crater.

In fact, only a slightly bigger impact than the one that created such a large crater on a small moon could have destroyed Mimas entirely. Herschel is a lunar impact crater located just to the north of the walled plain Ptolemaeus. The Cassini spacecraft made several close approaches and provided detailed images of Mimas. It is so large that astronomers have expressed surprise that Mimas was not shattered by the impact that caused it. It measures 139 kilometres (86 miles) acros… 495 000 km 2. If there were a crater of an equivalent scale on Earth it would be over 4,000 km (2,500 mi) in diameter and wider than Canada, with walls over 200 km (120 mi) high. The deposit appears to have a rille system associated Asteroid (2000) Herschel was discovered by J. Schubart at Sternwarte Sonneberg on July 29, 1960, and provisionally designated 1960 OA; a prediscovery observation had been designated 1934 NX. Diameter.

About a crater diameter to the northwest (35 km) is the walled plain Flammarion, along the southern edge of the Sinus Medii. On the rough inner floor is a notable central rise. ... Mimas has a very large and distinctive impact crater known as the Herschel Crater whose radius is nearly a third of Mimas' at about 130 km across. [4] If there were a crater of an equivalent scale on Earth it would be over 4,000 km (2,500 mi) in diameter – wider than Canada – with walls over 200 km (120 mi) high. Note the terraced walls and central peak. Craters on Mars close to the gale crater.jpg 516 × 387; 49 KB. John Herschel was honored by naming Moon crater J. Herschel (62.0N, 42.0W, 165 km diameter, in 1935) and (together with his father) Mars crater Herschel (14.9S, 230.3W, 304 km diameter). Its diameter is 39 km. The most conspicuous feature on Mimas is the 135 km-diameter crater Herschel (0 N, 111 W), which is nearly one-third the diameter of the satellite (Figs. Herschel (lunar crater) The lunar crater Herschel is in the centre of this image, with Ptolemaeus to its right. Herschel is a lunar impact crater located just to the north of the walled plain Ptolemaeus. Herschel Crater (130 kilometers, 80 miles wide) and some of the smaller craters seen in this mosaic show relatively dark markings along the lower portion of their crater walls (marked in green in the annotated version of the image). Herschel is the second-largest crater relative to its parent body of any equilibrium planetary moon in the Solar System after Tethys's crater Odysseus. The mare basalt layers were exposed during the excavation phase of the impact which created this 13.7 km diameter crater. Herschel is the second-largest crater relative to its parent body of any equilibrium planetary moon in the Solar System after Tethys's crater Odysseus. The crater is so large that it is surprising that Mimas was not shattered by the impact that caused it. / 62.0; -42.0 Coordinates: 62°00′N 42°00′W  /  62.0°N 42.0°W  / 62.0; -42.0. Diameter.

[3] Herschel has an estimated age of around 4.1 billion years. 1a, 2a, 3a, and 4). 396.4 km. Herschel has the form of a classic central-peak crater and appears to have not undergone detectable morphologic degradation at the resolution of the best Voyager images and Callisto, the 130 km-diameter “death star” crater Herschel on Saturn’s moon Mimas is a classic complex crater, as is the isostatically relaxed 400 km-diameter crater Odysseus on Tethys. [6][7] This is a coincidence, however, as the crater was not discovered until 1980, three years after the film was made. It is roughly 10 km (6 miles) deep and has outer walls about 5 km (3 miles) high. Mimas was discovered on Sept. 17, 1789 by English astronomer William Herschel, using his 40-foot reflector telescope.Ground-based astronomers could only see Mimas as little more than a dot until Voyagers I and II imaged it in 1980. John Herschel. It is named after the 18th-century astronomer William Herschel, who discovered Mimas in 1789. About a third the diameter of Mimas itself, Herschel crater gives the small moon an ominous appearance, especially for scifi fans of the Death Star battlestation of Star Wars fame. The 140 km (88 mi) Herschel Crater is about a third the diameter of the moon itself, and could have created fractures (chasmata) on the moon’s opposing side. Colongitude. By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Herschel. This peak is offset slightly to the west of the crater midpoint. Herschel crater, 40 km in diameter, is at the center of this frame taken looking towards the southeast from Apollo 12 in orbit about the Moon. Climate. It measures 130 km across, covering almost 1/3 of the diameter of the entire moon; its walls are approximately 5 km high, parts of its floor are 10 km deep, and its central peak rises 6 km above the crater … It was named after German-born British astronomer William Herschel. In fact, only a slightly bigger impact than the one that created such a large crater on a small moon could have destroyed Mimas entirely. Herschel (/ˈhɜːrʃəl/) is a large crater in the leading hemisphere of the Saturnian moon Mimas, on the equator at 100° longitude. 46° at sunrise. Herschel, named after William Herschel, is a HUGE crater on Mimas' surface. In this work, we study a dark dune field on the western side of Herschel crater, a 300 km diameter impact basin located near the Martian equator (14.4°S, 130°E), where the ripple and dune motion reflects the actual atmospheric wind conditions. Canuleia, about 6 miles (10 kilometers) in diameter… Normal herschel-clem1.jpg 398 × 400; 26 KB Normal herschel-LO-IV.jpg 453 × 412; 65 KB Ptolemaeus + Alphonsus + Hipparchus + Albategnius - LROC - WAC.JPG 3,014 × 3,344; 1.85 MB Herschel Martian crater 500km.jpg 540 × 540; 118 KB.

Herschel is a large crater in the leading hemisphere of the Saturnian moon Mimas, on the equator at 100° longitude. Earth Planet. It has a well-defined edge that is not significantly worn, and the inner walls are terraced. Its largest crater Herschel is nearly 140 kilometers wide. Chasmata that may be stress fractures due to shock waves from the impact traveling through it and focusing there can be seen on the opposite side of Mimas. If there were a crater of an equivalent scale on Earth it would be over 4,000 km in diameter and wider than Canada. The impact that formed Herschel must have nearly disrupted Mimas entirely. The rim of this crater is generally circular, although the western side is straight. Herschel Crater (130 kilometers, 80 miles wide) and some of the smaller craters seen in this mosaic show relatively dark markings along the lower portion of their crater walls (marked in green in the annotated version of the image).

The impact is also suspected of having something to do with the current "Pac-Man"–shaped temperature pattern on Mimas. Area. It is named after the 18th-century astronomer William Herschel, who discovered Mimas in 1789. Outcrops of layered mare basalt are visible in the interior wall of Caroline Herschel crater (located at 34.48°N, 328.71°E in western Mare Imbrium). 32 600 000 km 3.
