NGC 5683

NGC 5683 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 NGC 5683 rather than just read about it. In short: NGC 5683 is a type S0-a lenticular galaxy with a bar located in the Boötes constellation. It is 513 million light-years away from the Solar System and has an approximate diameter of 256,000 light-years meaning it is larger compared to the Milky Way.

Key takeaways

NGC 5683 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NGC 5683 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 5683 from memory before moving on to harder problems.

Reference excerpt

NGC 5683 is a type S0-a lenticular galaxy with a bar located in the Boötes constellation. It is 513 million light-years away from the Solar System and has an approximate diameter of 256,000 light-years meaning it is larger compared to the Milky Way. NGC 5683 was discovered by George Johnstone Stoney on April 13, 1850. NGC 5683 happens to lie near to a spiral galaxy NGC 5682, but they are far apart from each other. Nearby is another galaxy NGC 5689.

Characteristics NGC 5683 has an active galactic nucleus which presents strong x-rays. It is a Seyfert 1 type galaxy and such falls into the Markarian catalogue as Mrk 474, which its core shines in ultraviolet rays. The most accepted theory for this energy source of active galactic nuclei is the presence of an accretion disk around its supermassive black hole. It also shows high amounts of strong emission-lines which are mostly attributed to short-lived star formation in its regions likely restricted to a nuclear disk with its radius less than few hundred parsecs.

Supernova Type la supernova SN 2002db was discovered on May 18, 2002, in NGC 5683 by a collaboration of astronomers and Reiki Kushida from LOTOSS (Lick Observatory and Tenagra Observatory Supernova Searches). It was positioned 8 arcsecs west and 9 arcsecs north of the nucleus, with a magnitude of 17.6.

Worked examples

Example 1 — a first encounter with NGC 5683

Start with the simplest possible case. Write down what NGC 5683 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 NGC 5683 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 NGC 5683 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 NGC 5683

In research: NGC 5683 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 NGC 5683 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: NGC 5683 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1850, Boötes, IRAS catalogue objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 5683 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.
