NGC 2320

NGC 2320 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 2320 rather than just read about it. In short: NGC 2320 is an elliptical galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 6,020±16 km/s, which corresponds to a Hubble distance of 289.6 ± 20.3 Mly (88.80 ± 6.22 Mpc).

Key takeaways

NGC 2320 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 2320 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 2320 from memory before moving on to harder problems.

Reference excerpt

NGC 2320 is an elliptical galaxy in the constellation of Lynx. Its velocity with respect to the cosmic microwave background is 6,020±16 km/s, which corresponds to a Hubble distance of 289.6 ± 20.3 Mly (88.80 ± 6.22 Mpc). However, 14 non-redshift measurements give a closer mean distance of 278.44 ± 19.72 Mly (85.371 ± 6.045 Mpc). It was discovered by German-British astronomer William Herschel on 28 December 1790. NGC 2320 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure.

HDC 426 Group NGC 2320 is a member of a group of galaxies known as [CHM2007] HDC 426. This group contains 18 galaxies, including NGC 2315, NGC 2321, NGC 2322, NGC 2326, NGC 2332, NGC 2340, IC 458, and IC 465. NGC 2320 is also a member of the galaxy cluster Abell 569.

Supernova One supernova has been observed in NGC 2320:

SN 2000B (Type Ia, mag. 16.5) was discovered by French amateur astronomer Pierre Antonini on 11 January 2000.

Worked examples

Example 1 — a first encounter with NGC 2320

Start with the simplest possible case. Write down what NGC 2320 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 2320 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 2320 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 2320

In research: NGC 2320 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 2320 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 2320 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1790, Discoveries by William Herschel, Elliptical galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 2320 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.
