Magelhaens (lunar crater)

Magelhaens (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 Magelhaens (lunar crater) rather than just read about it. In short: Magelhaens is a lunar impact crater that lies along the southwestern edge of the Mare Fecunditatis, in the eastern part of the Moon's near side. It was named after 16th-century Portuguese explorer Ferdinand Magellan.

Key takeaways

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

Reference excerpt

Magelhaens is a lunar impact crater that lies along the southwestern edge of the Mare Fecunditatis, in the eastern part of the Moon's near side. It was named after 16th-century Portuguese explorer Ferdinand Magellan. It lies to the south-southwest of the crater Goclenius, about midway between Gutenberg to the northwest and Colombo to the southeast. This crater has a somewhat slender and uneven outer rim that is only roughly circular. The slightly smaller satellite crater Magelhaens A is attached to the southeastern rim. Within the inner walls of Magelhaens, the interior floor has been resurfaced by basaltic lava, matching the same dark appearance as the lunar mare to the northeast. This floor is level and almost featureless.

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 Magelhaens.

Worked examples

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

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

In research: Magelhaens (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 Magelhaens (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: Magelhaens (lunar crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ20 quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Magelhaens (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.
