Minoru Honda

Minoru Honda 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 Minoru Honda rather than just read about it. In short: Minoru Honda (本田実, Honda Minoru; February 26, 1913 – August 26, 1990) was a Japanese astronomer. Starting in 1937, Honda worked for Issei Yamamoto at the Zodiacal Light Observatory in Hiroshima.

Key takeaways

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

Reference excerpt

Minoru Honda (本田実, Honda Minoru; February 26, 1913 – August 26, 1990) was a Japanese astronomer. Starting in 1937, Honda worked for Issei Yamamoto at the Zodiacal Light Observatory in Hiroshima. He discovered twelve comets between 1940 and 1968, including the periodic comet 45P/Honda–Mrkos–Pajdušáková. He discovered on FH Serpentis (Nova Serpentis 1970) on February 13, 1970 from Kurashiki, Japan. He was the first to report the very bright V1500 Cygni (Nova Cygni 1975) at magnitude 3.0 on August 29, 1975; it peaked at 2.0, and many hundreds of independent discoveries were subsequently made by others. The asteroid 3904 Honda is named after him, 8485 Satoru is named after his wife, and 11442 Seijin-Sanso is named after his astronomical observatory.

Worked examples

Example 1 — a first encounter with Minoru Honda

Start with the simplest possible case. Write down what Minoru Honda 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 Minoru Honda 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 Minoru Honda 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 Minoru Honda

In research: Minoru Honda 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 Minoru Honda 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: Minoru Honda is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 1990 deaths, 20th-century Japanese astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Minoru Honda 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.
