NGC 2814

NGC 2814 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 2814 rather than just read about it. In short: NGC 2814 is a small spiral galaxy in the constellation Ursa Major. Its velocity relative to the cosmic microwave background is 1,693 ± 8 km/s, which corresponds to a Hubble distance of 24.97 ± 1.75 Mpc (~81.5 million light years.).

Key takeaways

NGC 2814 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 2814 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 2814 from memory before moving on to harder problems.

Reference excerpt

NGC 2814 is a small spiral galaxy in the constellation Ursa Major. Its velocity relative to the cosmic microwave background is 1,693 ± 8 km/s, which corresponds to a Hubble distance of 24.97 ± 1.75 Mpc (~81.5 million light years.). German-British astronomer William Herschel discovered this galaxy on 3 April 1791. NGC 2814 has a luminosity class of II.

Holmberg 124 NGC 2814 has three galactic neighbours: the side-on spiral galaxy NGC 2820, the irregular galaxy IC 2458, and the face-on non-barred spiral galaxy NGC 2805. Collectively, the four galaxies make up the galaxy group known as Holmberg 124.

Supernova One supernova has been observed in NGC 2814: SN 2020mmz (Type II, mag. 17.0528) was discovered by the Zwicky Transient Facility on 13 June 2020.

Worked examples

Example 1 — a first encounter with NGC 2814

Start with the simplest possible case. Write down what NGC 2814 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 2814 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 2814 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 2814

In research: NGC 2814 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 2814 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 2814 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1791, Discoveries by William Herschel, Galaxies discovered in 1791, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 2814 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.
