NGC 466

NGC 466 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 466 rather than just read about it. In short: NGC 466 is a lenticular galaxy located about 247 million light-years away from Earth in the constellation Tucana. NGC 466 was discovered by astronomer John Herschel on October 3, 1836.

Key takeaways

NGC 466 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 466 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 466 from memory before moving on to harder problems.

Reference excerpt

NGC 466 is a lenticular galaxy located about 247 million light-years away from Earth in the constellation Tucana. NGC 466 was discovered by astronomer John Herschel on October 3, 1836.

NGC 434 group NGC 466 is a member of the NGC 434 galaxy group (also known as LGG 19). This group includes at least 10 galaxies, including NGC 434, NGC 434A, NGC 440, NGC 484, IC 1649, and four from the ESO catalogue.

Supernova One supernova has been observed in NGC 466: SN 2025rib (Type Ia-91bg-like, mag. 18.186) was discovered by ATLAS on 16 July 2025.

Worked examples

Example 1 — a first encounter with NGC 466

Start with the simplest possible case. Write down what NGC 466 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 466 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 466 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 466

In research: NGC 466 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 466 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 466 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1836, Discoveries by John Herschel, Lenticular galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 466 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.

Frequently asked questions

What is NGC 466 in simple terms?

NGC 466 is a lenticular galaxy located about 247 million light-years away from Earth in the constellation Tucana. NGC 466 was discovered by astronomer John Herschel on October 3, 1836.

Why does NGC 466 matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study NGC 466?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
