NGC 487

NGC 487 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 487 rather than just read about it. In short: NGC 487 is a barred spiral galaxy located about 250 million light-years away from Earth in the constellation Cetus. NGC 487's calculated velocity is 5,949 km/s.

Key takeaways

NGC 487 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 487 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 487 from memory before moving on to harder problems.

Reference excerpt

NGC 487 is a barred spiral galaxy located about 250 million light-years away from Earth in the constellation Cetus. NGC 487's calculated velocity is 5,949 km/s. NGC 487 was discovered by American astronomer Francis Leavenworth on November 28, 1885.

Worked examples

Example 1 — a first encounter with NGC 487

Start with the simplest possible case. Write down what NGC 487 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 487 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 487 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 487

In research: NGC 487 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 487 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 487 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1885, Barred spiral galaxies, Barred spiral galaxy stubs, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 487 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 487 in simple terms?

NGC 487 is a barred spiral galaxy located about 250 million light-years away from Earth in the constellation Cetus. NGC 487's calculated velocity is 5,949 km/s.

Why does NGC 487 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 487?

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.
