NGC 3512

NGC 3512 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 3512 rather than just read about it. In short: NGC 3512 is an intermediate spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1,677±21 km/s, which corresponds to a Hubble distance of 80.7 ± 5.7 Mly (24.73 ± 1.76 Mpc).

Key takeaways

NGC 3512 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 3512 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 3512 from memory before moving on to harder problems.

Reference excerpt

NGC 3512 is an intermediate spiral galaxy in the constellation of Leo. Its velocity with respect to the cosmic microwave background is 1,677±21 km/s, which corresponds to a Hubble distance of 80.7 ± 5.7 Mly (24.73 ± 1.76 Mpc). However, four non-redshift measurements give a farther mean distance of 113.50 ± 11.20 Mly (34.800 ± 3.434 Mpc). It was discovered by German-British astronomer William Herschel on 11 April 1785. NGC 3512 is a LINER galaxy, i.e. a galaxy whose nucleus has an emission spectrum characterized by broad lines of weakly ionized atoms.

NGC 3504 group NGC 3512 is a member of the NGC 3504 Group (also known as LGG 227), which is a member of the Leo II Groups, a series of galaxies and galaxy clusters strung out from the western edge of the Virgo Supercluster. There are eight other galaxies in the group, including NGC 3380, NGC 3400, NGC 3414, NGC 3451, NGC 3504, UGC 5921 and UGC 5958. This NGC 3504 group is also mentioned by Abraham Mahtessian in his research paper published in 1998.

Supernova One supernova has been observed in NGC 3512:

SN 2001fv (Type II, mag. 16.4) was discovered by British amateur astronomer Mark Armstrong on 3 November 2001.

Worked examples

Example 1 — a first encounter with NGC 3512

Start with the simplest possible case. Write down what NGC 3512 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 3512 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 3512 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 3512

In research: NGC 3512 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 3512 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 3512 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1785, Discoveries by William Herschel, IRAS catalogue objects, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 3512 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.
