NGC 4200

NGC 4200 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 4200 rather than just read about it. In short: NGC 4200 is a small lenticular galaxy located in the constellation of Virgo. NGC 4200 was discovered by the German-British astronomer William Herschel in 1784.

Key takeaways

NGC 4200 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 4200 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 4200 from memory before moving on to harder problems.

Reference excerpt

NGC 4200 is a small lenticular galaxy located in the constellation of Virgo. NGC 4200 was discovered by the German-British astronomer William Herschel in 1784.

The M49 and M60 groups and the Virgo Cluster According to A.M. Garcia, NGC 4200 is one of the many galaxies in the M49 group (127 in total), which he described in an article published in 1993. This list includes 63 galaxies from the New General Catalogue , including NGC 4382 (M85), NGC 4472 (M49), NGC 4649 (M60), as well as 20 galaxies from the Index Catalogue. On the other hand, NGC 4423 also appears in a list of 227 galaxies in an article published by Abraham Mahtessian in 1998. This list includes more than 200 galaxies from the New General Catalogue and about fifteen galaxies from the Index Catalogue. Ten other galaxies from the Messier Catalogue are also found in this list: M49, M58, M60, M61, M85, M87, M88, M91, M99, and M100. Not all the galaxies in Mahtessian's list actually constitute a single galaxy group. Rather, they are several groups of galaxies, all part of a galaxy cluster, the Virgo Cluster. To avoid confusion with the Virgo Cluster, this collection of galaxies can be called the M60 Group, as M60 is one of the brightest galaxies on the list. The Virgo Cluster is indeed much larger and is estimated to contain around 1,300 galaxies, and possibly more than 2,000, located at the core of the Virgo Supercluster, which includes the Local Group. Many galaxies in Mahtessian's list are found in eleven groups described in the article by AM Garcia, namely the NGC 4123 group (7 galaxies), the NGC 4261 group (13 galaxies), the NGC 4235 group (29 galaxies), the M88 group (13 galaxies, M88 = NGC 4501), the NGC 4461 group (9 galaxies), the M61 group (32 galaxies, M61 = NGC 4303), the NGC 4442 group (13 galaxies), the M87 group (96 galaxies, M87 = NGC 4486), the M49 group (127 galaxies, M49 = NGC 4472), the NGC 4535 group (14 galaxies) and the NGC 4753 group (15 galaxies). These eleven groups are part of the Virgo Cluster and contain 396 galaxies. However, some galaxies from Mahtessian's list do not appear in any of Garcia's groups, and vice versa.

Worked examples

Example 1 — a first encounter with NGC 4200

Start with the simplest possible case. Write down what NGC 4200 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 4200 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 4200 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 4200

In research: NGC 4200 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 4200 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 4200 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lenticular galaxies, Lenticular galaxy stubs, NGC objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 4200 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.
