Takeshi Urata

Takeshi Urata 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 Takeshi Urata rather than just read about it. In short: Takeshi Urata (浦田武, Urata Takeshi; 1947 – December 15, 2012) was a Japanese astronomer. He was a prolific discoverer of asteroids, observing at Nihondaira Observatory.

Key takeaways

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

Reference excerpt

Takeshi Urata (浦田武, Urata Takeshi; 1947 – December 15, 2012) was a Japanese astronomer. He was a prolific discoverer of asteroids, observing at Nihondaira Observatory. In 1978 he became the first amateur to discover a minor planet (2090 Mizuho) in over fifty years, which he named after his daughter, Mizuho. His pioneering feat led to an upsurge in such discoveries. In the ten years that followed, amateurs from Japan discovered 160 minor planets. Urata shared his observation data with peer astronomers in Japan on a periodical called "Tenkai" (the Heavens), as well as contributed to academic journals such as Advances in Space Research and participated in poster presentations at astronomical conferences. Urata co-discovered the periodic comet 112P/Urata-Niijima in 1986. One of the most active amateur astronomers in Japan, he was also an editor of the Japanese Ephemerides of Minor Planets. The 1927-discovered asteroid 3722 Urata is named after him.

Worked examples

Example 1 — a first encounter with Takeshi Urata

Start with the simplest possible case. Write down what Takeshi Urata 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 Takeshi Urata 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 Takeshi Urata 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 Takeshi Urata

In research: Takeshi Urata 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 Takeshi Urata 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: Takeshi Urata is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, 2012 deaths, 20th-century Japanese astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Takeshi Urata 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.
