Harunobu is a crater on Mercury. It has a diameter of 107 kilometers. Its name was adopted by the International Astronomical Union in 1976. Harunobu is named for the Japanese artist Suzuki Harunobu, who lived from 1720 or 1724 to 1770.

Harunobu (crater)
Harunobu (crater) 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 Harunobu (crater) rather than just read about it. In short: Harunobu is a crater on Mercury. It has a diameter of 107 kilometers.
Key takeaways
- Harunobu (crater) belongs to astronomy; place it in that map before memorising details.
- Learn the definition first, then one example that makes the definition concrete.
- Connect Harunobu (crater) to a quantity you can measure, compute or draw — that is where exam questions come from.
- Reproduce the core statement of Harunobu (crater) from memory before moving on to harder problems.

Worked examples
Example 1 — a first encounter with Harunobu (crater)
Start with the simplest possible case. Write down what Harunobu (crater) 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 Harunobu (crater) 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 Harunobu (crater) 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 Harunobu (crater)
- In research
- Harunobu (crater) 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 Harunobu (crater) 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
- Harunobu (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on Mercury, Mercury (planet) stubs, so understanding it makes those chapters shorter.
- In everyday life
- Look for Harunobu (crater) 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.
