Leonid Elenin

Leonid Elenin 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 Leonid Elenin rather than just read about it. In short: Leonid Vladimirovich Elenin (Russian: Леони́д Влади́мирович Еле́нин; born 10 August 1981) is a Russian amateur astronomer working with the ISON-NM observatory (H15) via the International Scientific Optical Network (ISON), which is the first Russian remote observatory in the West. Leonid Elenin works for the Keldysh Institute of Applied Mathematics and lives in Lyubertsy, Moscow region, Russia.

Key takeaways

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

Reference excerpt

Leonid Vladimirovich Elenin (Russian: Леони́д Влади́мирович Еле́нин; born 10 August 1981) is a Russian amateur astronomer working with the ISON-NM observatory (H15) via the International Scientific Optical Network (ISON), which is the first Russian remote observatory in the West. Leonid Elenin works for the Keldysh Institute of Applied Mathematics and lives in Lyubertsy, Moscow region, Russia. Leonid Elenin is best known for discovering the comet C/2010 X1 on 10 December 2010. Elenin then discovered comet P/2011 NO1 on 7 July 2011. As of 2019, Elenin had discovered five comets. The first asteroid discovered by Leonid Elenin was 2008 XE on 1 December 2008 at Tzec (H10). The first Amor asteroid (near-Earth object) discovered by Elenin was 2010 RN80 on 10 September 2010 at ISON-NM (H15). Elenin has also discovered the trailing L5 Jupiter trojan 2011 QJ9 on 23 August 2011, the Mars-crossing asteroid 2011 QD23 on 25 August 2011, and the amor asteroid (Near-Earth object) 2011 QY37 on 27 August 2011. The first numbered asteroid discovered by Elenin at ISON-NM is 365756 ISON (2010 WZ71). On 29 January 2013, the Minor Planet Center awarded Leonid Elenin a 2012 Edgar Wilson Award for the discovery of comets by amateurs.

Worked examples

Example 1 — a first encounter with Leonid Elenin

Start with the simplest possible case. Write down what Leonid Elenin 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 Leonid Elenin 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 Leonid Elenin 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 Leonid Elenin

In research: Leonid Elenin 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 Leonid Elenin 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: Leonid Elenin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1981 births, 21st-century Russian astronomers, Amateur astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Leonid Elenin 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.
