Hohmann (crater)

Hohmann (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 Hohmann (crater) rather than just read about it. In short: Hohmann is a lunar impact crater that lies within the central basin of the Mare Orientale formation, on the farside of the Moon. It is located to the south of the crater Maunder, and to the west of Kopff crater.

Key takeaways

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

Reference excerpt

Hohmann is a lunar impact crater that lies within the central basin of the Mare Orientale formation, on the farside of the Moon. It is located to the south of the crater Maunder, and to the west of Kopff crater. Due to its proximity to the western lunar limb, this area of the surface is occasionally visible during favorable librations. However the basin is viewed from the side, restricting the amount of detail that can be observed from Earth. The rim of this crater is circular and only marginally worn, with a pair of tiny impacts overlaying the southern edge. An outer rampart slopes down to the surrounding surface, and the interior wall slopes down more sharply to the crater floor. There is a terrace along the southeastern interior wall. Portions of the surroundings show evidence of ejecta deposits from Maunder to the north (as shown by a number of secondary impacts). Some of this ejecta may have been deposited within the interior of Hohmann.

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 Hohmann.

The following crater has been renamed by the IAU.

Worked examples

Example 1 — a first encounter with Hohmann (crater)

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

In research: Hohmann (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 Hohmann (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: Hohmann (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ17 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Hohmann (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.
