King (crater)

King (crater) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand King (crater) rather than just read about it. In short: King is a prominent lunar impact crater that is located on the far side of the Moon, and cannot be viewed directly from Earth. The crater was named after Arthur Scott King and Edward Skinner King in 1970.

Key takeaways

King (crater) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect King (crater) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of King (crater) from memory before moving on to harder problems.

Reference excerpt

King is a prominent lunar impact crater that is located on the far side of the Moon, and cannot be viewed directly from Earth. The crater was named after Arthur Scott King and Edward Skinner King in 1970. Prior to that, this crater was known as Crater 211. It forms a pair with Ibn Firnas, which is only slightly larger and is attached to the northeast rim of King. To the northwest is the crater Lobachevskiy, and Guyot is located an equal distance to the north-northwest. Due to its prominent rays, King is mapped as part of the Copernican System on the lunar geologic timescale. The outer rim of King is roughly circular but with a slightly irregular appearance, particularly at the northern end. The crater displays little appearance of wear. The inner walls are terraced, particularly along the eastern side. Within the walls is a somewhat uneven interior floor. The interior is irregular and ridged, particularly in the eastern half. The elongated, Y-shaped central rise is part of a ridge that runs to the southern rim. The spectra of the central peak fits an olivine-bearing gabbro mineralogy, which originated from a depth of 7.6 to 11.9 km. The infrared spectrum of pure crystalline plagioclase has been identified on the central floor.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to King.

King Y is to the north of King, and it is now a "pool" of impact melt, filled at the time of the King impact. The name "Al-Tusi" had been suggested for King Y, but this was not approved by the IAU. King J is a small crater to the southeast of King, and it is covered by King's ejecta blanket.

Sita crater A tiny crater near the east-southeastern inner wall has been officially given the Indian feminine name Sita by the IAU. It is located at selenographic coordinates 4.6° N, 120.8° E, and has a diameter of 2 kilometres.

Mountain Peaks

Several mountain peaks (Montes) within King crater have been named. The names were approved by the IAU in 1976.

Worked examples

Example 1 — a first encounter with King (crater)

Start with the simplest possible case. Write down what King (crater) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to King (crater) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about King (crater) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of King (crater)

In research: King (crater) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses King (crater) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: King (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ14 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for King (crater) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
