NGC 4363

NGC 4363 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 4363 rather than just read about it. In short: NGC 4363 is a spiral galaxy in the constellation of Draco. Its velocity with respect to the cosmic microwave background is 1474 ± 3 km/s, which corresponds to a Hubble distance of 21.75 ± 1.52 Mpc (~71 million light-years).

Key takeaways

NGC 4363 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 4363 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 4363 from memory before moving on to harder problems.

Reference excerpt

NGC 4363 is a spiral galaxy in the constellation of Draco. Its velocity with respect to the cosmic microwave background is 1474 ± 3 km/s, which corresponds to a Hubble distance of 21.75 ± 1.52 Mpc (~71 million light-years). The galaxy was discovered by German-British astronomer William Herschel on 10 December 1797. On 31 October 2023, Kōichi Itagaki discovered a supernova in NGC 4363: SN 2023wcr (Type II, mag. 16).

NGC 4589 Group NGC 4363 is a bright galaxy in the X-ray range and is part of the NGC 4589 group which includes at least 17 other galaxies also bright in the X-ray range: NGC 4127, NGC 4133, NGC 4159, NGC 4291, NGC 4319, NGC 4331, NGC 4386, NGC 4589, NGC 4648, UGC 7086, UGC 7189, UGC 7238, UGC 7265, UGC 7844, UGC 7872 and UGC 7908.

Worked examples

Example 1 — a first encounter with NGC 4363

Start with the simplest possible case. Write down what NGC 4363 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 4363 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 4363 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 4363

In research: NGC 4363 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 4363 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 4363 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1797, Discoveries by William Herschel, Draco (constellation), so understanding it makes those chapters shorter.
In everyday life: Look for NGC 4363 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.
