Perepelkin (lunar crater)

Perepelkin (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 Perepelkin (lunar crater) rather than just read about it. In short: Perepelkin is a lunar impact crater that is located on the far side of the Moon, just to the south of the similar crater Love. Attached to the exterior of its southern rim is the smaller Shirakatsi.

Key takeaways

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

Reference excerpt

Perepelkin is a lunar impact crater that is located on the far side of the Moon, just to the south of the similar crater Love. Attached to the exterior of its southern rim is the smaller Shirakatsi. Less than one crater diameter to the east-northeast is Lane, and to the west-southwest are the co-joined Danjon and D'Arsonval. The rim of this crater is relatively heavily eroded, and is similar in appearance to Love to the north. Along the western inner wall is an odd, pear-shaped crater that is probably a merge of two impacts. There is a short chain of small craters along the southwestern inner wall. The floor is pitted by tiny impacts, but is relatively level compared to the surrounding terrain. There is a small central peak at the midpoint that has a ridge extension to the southeast. The crater was named after Soviet astrophysicist Yevgeny Perepyolkin by the IAU in 1970. The crater was known as Crater 285 prior to naming.

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 Perepelkin.

Worked examples

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

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

In research: Perepelkin (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 Perepelkin (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: Perepelkin (lunar crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ22 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Perepelkin (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.
