Pingré (crater)

Pingré (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 Pingré (crater) rather than just read about it. In short: Pingré is a lunar impact crater that is located near the southwest limb of the Moon, beyond the large crater Phocylides. It lies to the northwest of the huge walled basin Bailly, and to the east of the smaller Graff.

Key takeaways

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

Reference excerpt

Pingré is a lunar impact crater that is located near the southwest limb of the Moon, beyond the large crater Phocylides. It lies to the northwest of the huge walled basin Bailly, and to the east of the smaller Graff. Due to its location, this crater appears foreshortened when viewed from the Earth. The outer rim of this crater has become worn due to minor impacts, leaving the features rounded and irregular. The wall is nearly disintegrated in the southeast, and is overlain by a small crater along the eastern rim. The rim is also low and slumped to the northwest. The interior floor is relatively level, but marked by several small craters, which may be secondaries from Hausen or a more distal crater. These craters occur near the midpoint of the floor where a central peak may once have existed. Pingré lies to the southeast of the Mendel-Rydberg Basin, a 630 km wide impact basin of Nectarian age.

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 Pingré.

The following craters have been renamed by the IAU.

Worked examples

Example 1 — a first encounter with Pingré (crater)

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

In research
Pingré (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 Pingré (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
Pingré (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ25 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Pingré (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.
