Tomimaru Okuni

Tomimaru Okuni 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 Tomimaru Okuni rather than just read about it. In short: Tomimaru Okuni (大国富丸, Ōkuni Tomimaru; born 1931) is a Japanese amateur astronomer and a discoverer of minor planets at the Nanyo Observatory (358), Yamagata prefecture, Japan. He is a prolific discoverer of asteroids, credited by the Minor Planet Center with a total of 130 discoveries between 1995 and 2000.

Key takeaways

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

Reference excerpt

Tomimaru Okuni (大国富丸, Ōkuni Tomimaru; born 1931) is a Japanese amateur astronomer and a discoverer of minor planets at the Nanyo Observatory (358), Yamagata prefecture, Japan. He is a prolific discoverer of asteroids, credited by the Minor Planet Center with a total of 130 discoveries between 1995 and 2000. The main-belt asteroid 7769 Okuni, discovered by Satoru Otomo at the Kiyosato Observatory in 1991, is named in his honour. Naming citation was published on 9 January 2001 (M.P.C. 41935).

Worked examples

Example 1 — a first encounter with Tomimaru Okuni

Start with the simplest possible case. Write down what Tomimaru Okuni 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 Tomimaru Okuni 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 Tomimaru Okuni 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 Tomimaru Okuni

In research: Tomimaru Okuni 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 Tomimaru Okuni 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: Tomimaru Okuni is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, 20th-century Japanese astronomers, Discoverers of asteroids, so understanding it makes those chapters shorter.
In everyday life: Look for Tomimaru Okuni 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.
