Osamu Muramatsu

Osamu Muramatsu is a astronomy 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 Osamu Muramatsu rather than just read about it. In short: Osamu Muramatsu (村松修, Muramatsu Osamu; born 1949) is a Japanese astronomer and discoverer of asteroids and comets. He is credited by the Minor Planet Center with the discovery of 73 minor planets.

Key takeaways

Osamu Muramatsu belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Osamu Muramatsu to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Osamu Muramatsu from memory before moving on to harder problems.

Reference excerpt

Osamu Muramatsu (村松修, Muramatsu Osamu; born 1949) is a Japanese astronomer and discoverer of asteroids and comets. He is credited by the Minor Planet Center with the discovery of 73 minor planets. He also co-discovered 147P/Kushida-Muramatsu, a periodic comet. Muramatsu works at the planetarium in the Shibuya ward of Tokyo, Japan. The inner main-belt asteroid 5606 Muramatsu, discovered by astronomer and colleague Satoru Otomo, was named in his honor on 28 July 1999 (M.P.C. 35483).

Worked examples

Example 1 — a first encounter with Osamu Muramatsu

Start with the simplest possible case. Write down what Osamu Muramatsu claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Osamu Muramatsu 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 Osamu Muramatsu 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 Osamu Muramatsu

In research: Osamu Muramatsu appears in astronomy 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 Osamu Muramatsu 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: Osamu Muramatsu is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1949 births, 20th-century Japanese astronomers, Discoverers of asteroids, so understanding it makes those chapters shorter.
In everyday life: Look for Osamu Muramatsu 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.
