UGC 3730

UGC 3730 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 UGC 3730 rather than just read about it. In short: UGC 3730 or Arp 141 is a ring galaxy in the constellation Camelopardalis. The galaxy lies about 130 million light years away from Earth, which means, given its apparent dimensions, that UGC 3730 is approximately 110,000 light years across.

Key takeaways

UGC 3730 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect UGC 3730 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of UGC 3730 from memory before moving on to harder problems.

Reference excerpt

UGC 3730 or Arp 141 is a ring galaxy in the constellation Camelopardalis. The galaxy lies about 130 million light years away from Earth, which means, given its apparent dimensions, that UGC 3730 is approximately 110,000 light years across. The galaxy is included in Halton Arp's Atlas of Peculiar Galaxies in the elliptical galaxies emanating material category. UGC 3730 has been the result of galaxy interaction. The interaction has led one galaxy to turn into an asymmetric ring. The companion, a lenticular galaxy, lies along the major axis of the ring and it is estimated to have a larger mass than the ring galaxy. The nucleus of the ring galaxy lies between the ring and companion galaxy. Emission has been observed in the interior of the ring as well as between the ring galaxy and the companion galaxy and stars have been tidally stripped from the ring galaxy. The star formation rate of the ring galaxy is estimated to be 0.26 M☉ per year. The total stellar mass of the galaxy is estimated to be 8.3×109 M☉ and the total gas mass to be 4.9×109 M☉. UGC 3730 forms a pair with UGC 3705 which lies 9.4 arcminutes away. Both galaxies are part of the LGG 141 galaxy group, which also includes UGC 3697, UGC 3714, UGC 3804, UGC 3838, UGC 3878, UGC 3626, UGC 3644, and UGC 3701.

Worked examples

Example 1 — a first encounter with UGC 3730

Start with the simplest possible case. Write down what UGC 3730 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 UGC 3730 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 UGC 3730 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 UGC 3730

In research: UGC 3730 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 UGC 3730 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: UGC 3730 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arp objects, Camelopardalis, Interacting galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for UGC 3730 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.
