Kesen meteorite

Kesen meteorite is a science 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 Kesen meteorite rather than just read about it. In short: The Kesen meteorite fell on 13 June 1850, landing in a swamp in the outskirts of the city of Rikuzentakata, Kesen District in Iwate Prefecture, Japan. Classification It was classified as a H4-type ordinary chondrite.

Key takeaways

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

Reference excerpt

The Kesen meteorite fell on 13 June 1850, landing in a swamp in the outskirts of the city of Rikuzentakata, Kesen District in Iwate Prefecture, Japan.

Classification It was classified as a H4-type ordinary chondrite.

Main mass The meteorite initially weighed 135 kilograms (298 lb), however some local residents cut off pieces for charms or souvenirs such that its current weight is 106 kilograms (234 lb). The meteorite was moved to Tokyo where it was held in the Imperial Household Museum. It is currently housed at the National Museum of Nature and Science, Tokyo. A full-scale replica was housed at the Rikuzentakata Municipal Museum until it was lost in the 2011 Tōhoku tsunami.

Worked examples

Example 1 — a first encounter with Kesen meteorite

Start with the simplest possible case. Write down what Kesen meteorite claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Kesen meteorite 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 Kesen meteorite 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 Kesen meteorite

In research: Kesen meteorite appears in science 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 Kesen meteorite 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: Kesen meteorite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chondrite meteorites, Meteorites found in Japan, so understanding it makes those chapters shorter.
In everyday life: Look for Kesen meteorite 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.
