Kazuro Watanabe

Kazuro Watanabe 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 Kazuro Watanabe rather than just read about it. In short: Kazuo Watanabe (渡辺和郎, Watanabe Kazuo; born May 1, 1955) is a Japanese amateur astronomer and prolific discoverer of minor planets. He was born in Hokkaidō, Japan and is a member of the Astronomical Society of Japan as well as of the Oriental Astronomical Association.

Key takeaways

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

Reference excerpt

Kazuo Watanabe (渡辺和郎, Watanabe Kazuo; born May 1, 1955) is a Japanese amateur astronomer and prolific discoverer of minor planets. He was born in Hokkaidō, Japan and is a member of the Astronomical Society of Japan as well as of the Oriental Astronomical Association. Through publications and the direction of junior associates, this asteroid hunter has been responsible for the discovery of nearly 700 asteroids, many of them in association with Kin Endate. He is the author or co-author of the Japanese publications Asteroid Hunter (小惑星ハンター), Celestial Body Photography Manual (天体写真マニュアル), The Celestial Sky of Our Dreams (僕らの夢の星空), as well as others. He is also a frequent contributor to the Japanese periodical Monthly Astronomical Guide (月刊天文ガイド). The minor planet 4155 Watanabe has been named in his honor.

Discoveries

Names of some asteroids

Mamiya (間宮, 12127) – Named after the famous Edo-period detective, Mamiya Rinzō. Tentaikojo (天体工場, 12713) – Named after the museum of that name in Sapporo.

List of discovered asteroids Kazuo Watanabe is credited by the Minor Planet Center with the discovery of 671 minor planets made between 1987 and 2000. Some of his discoveries include (in alphabetical order) the minor planets 4263 Abashiri (Florian asteroid), 4585 Ainonai, 46610 Bésixdouze, 5331 Erimomisaki, 3915 Fukushima, 5474 Gingasen (Vestian binary), 9971 Ishihara, 11949 Kagayayutaka, 5481 Kiuchi, 6498 Ko (slow rotator), 6500 Kodaira (a Mars-crosser), 6980 Kyusakamoto (Koronian asteroid), 4607 Seilandfarm (rare-type binary), 5357 Sekiguchi and 5692 Shirao.

Worked examples

Example 1 — a first encounter with Kazuro Watanabe

Start with the simplest possible case. Write down what Kazuro Watanabe 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 Kazuro Watanabe 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 Kazuro Watanabe 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 Kazuro Watanabe

In research: Kazuro Watanabe 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 Kazuro Watanabe 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: Kazuro Watanabe is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 20th-century Japanese astronomers, Discoverers of asteroids, so understanding it makes those chapters shorter.
In everyday life: Look for Kazuro Watanabe 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.
