NGC 4062

NGC 4062 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 4062 rather than just read about it. In short: NGC 4062 is a spiral galaxy in the constellation Ursa Major. The galaxy lies about 50 million light years away from Earth, which means, given its apparent dimensions, that NGC 4062 is approximately 50,000 light years across.

Key takeaways

NGC 4062 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 4062 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 4062 from memory before moving on to harder problems.

Reference excerpt

NGC 4062 is a spiral galaxy in the constellation Ursa Major. The galaxy lies about 50 million light years away from Earth, which means, given its apparent dimensions, that NGC 4062 is approximately 50,000 light years across. It was discovered by William Herschel on March 20, 1787.

Characteristics NGC 4062 has a small elliptical bulge. From the minor axis of the bulge emerge two spiral arms, better visible in near-infrared. The arms are high-contrast and in a grand design pattern. The arms are initially smooth and narrow but after half a revolution become diffuse. They can be traced for a full revolution before fading. Dust lanes can be seen across the disk in a spiral pattern. Some HII regions are also visible, but are less than two arcseconds across. The star formation knots appear patchy, in a flocculent pattern. The galaxy is a strong source of H-alpha emission, whose kinematics in the central region indicate high velocity dispersion, maybe due to the presence of a bar. In the centre of the galaxy lies a supermassive black hole whose mass is estimated to be 106.7 M☉ (5 million times more massive than the Sun) based on the spheroid luminosity.

Nearby galaxies NGC 4062 is a member of the NGC 4274 Group (also known as LGG 279) which has at least 19 galaxies, including NGC 4020, NGC 4136, NGC 4173, NGC 4203, NGC 4245, NGC 4251, NGC 4274, NGC 4278, NGC 4283, NGC 4310, NGC 4314, NGC 4359, NGC 4414, NGC 4509, NGC 4525, UGC 7300, and MCG +05-29-066. Makarov considers the galaxy to be a member of the NGC 4062 Group, which also includes NGC 4020, IC 2984, and UGC 7007.

Worked examples

Example 1 — a first encounter with NGC 4062

Start with the simplest possible case. Write down what NGC 4062 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 4062 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 4062 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 4062

In research: NGC 4062 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 4062 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 4062 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1787, Coma I Group, Discoveries by William Herschel, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 4062 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.
