Proctor (lunar crater)

Proctor (lunar 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 Proctor (lunar crater) rather than just read about it. In short: Proctor is the remnant of a lunar impact crater that is located to the southeast of the prominent crater Tycho. It lies just to the north of the huge walled plain named Maginus.

Key takeaways

Proctor (lunar 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 Proctor (lunar crater) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Proctor (lunar crater) from memory before moving on to harder problems.

Reference excerpt

Proctor is the remnant of a lunar impact crater that is located to the southeast of the prominent crater Tycho. It lies just to the north of the huge walled plain named Maginus. To the north is the crater Saussure and to the northwest, just to the east of Tycho, lies Pictet. Proctor is 52 kilometers (32 mi) in diameter and its walls are 1,300 meters (4,300 ft) high. It is from the Pre-Imbrian period, which lasted from 4.55 to 3.85 billion years ago. The outer rim of this crater has become heavily worn and eroded, and now forms a low, irregular rise around the interior floor. Much of the northwestern half of the rim is marked by a number of small craters, including Proctor D. The interior floor is somewhat level and is marked only by a few tiny impacts. The crater is named after the 20th-century American astronomy writer Mary Proctor.

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 Proctor.

Worked examples

Example 1 — a first encounter with Proctor (lunar crater)

Start with the simplest possible case. Write down what Proctor (lunar 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 Proctor (lunar 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 Proctor (lunar 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 Proctor (lunar crater)

In research: Proctor (lunar 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 Proctor (lunar 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: Proctor (lunar crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ26 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Proctor (lunar 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.
