IC 2628

IC 2628 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 IC 2628 rather than just read about it. In short: IC 2628 is a type SBa barred spiral galaxy with a ring located in Leo constellation. It is located 600 million light-years from the Solar System and has an approximate diameter of 135,000 light-years.

Key takeaways

IC 2628 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IC 2628 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IC 2628 from memory before moving on to harder problems.

Reference excerpt

IC 2628 is a type SBa barred spiral galaxy with a ring located in Leo constellation. It is located 600 million light-years from the Solar System and has an approximate diameter of 135,000 light-years. IC 2628 was discovered on March 27, 1906, by Max Wolf and is classified as a ring galaxy due to its peculiar appearance. The galaxy has a surface brightness of magnitude 23.8 and located at right ascension (11:11:37.8) and declination (+12:07:21) respectively.

Worked examples

Example 1 — a first encounter with IC 2628

Start with the simplest possible case. Write down what IC 2628 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 IC 2628 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 IC 2628 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 IC 2628

In research: IC 2628 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 IC 2628 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: IC 2628 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1906, Barred spiral galaxies, Discoveries by Max Wolf, so understanding it makes those chapters shorter.
In everyday life: Look for IC 2628 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.
