NGC 5112

NGC 5112 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 5112 rather than just read about it. In short: NGC 5112 is a barred spiral galaxy in the constellation Canes Venatici. It was discovered on 17 March 1787 by German-British astronomer William Herschel.

Key takeaways

NGC 5112 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 5112 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 5112 from memory before moving on to harder problems.

Reference excerpt

NGC 5112 is a barred spiral galaxy in the constellation Canes Venatici. It was discovered on 17 March 1787 by German-British astronomer William Herschel. This galaxy is in close physical proximity to the edge-on dwarf spiral NGC 5107. On 4 March 2015, a supernova candidate, designated PSN J13215756+3843229, was discovered in NGC 5112 by Robert Gagliano, Dick Post, Jack Newton, and Tim Puckett. Spectral analysis suggested that it was instead a supernova imposter, possibly an outburst from a luminous blue variable. An outburst from this star was observed by GOTO on 4 May 2025, and designated AT 2025jsi.

NGC 5005 Group According to A. M. Garcia, NGC 5112 is part of the NGC 5005 group (also known as LGG 334). This group of galaxies contains at least 16 members. The other galaxies in the group are: NGC 4861, NGC 5002, NGC 5005, NGC 5014, NGC 5033, NGC 5107, IC 4182, IC 4213, UGC 8181, UGC 8246, UGC 8261, UGC 8303, UGC 8314, UGC 8315, and UGC 8323.

Worked examples

Example 1 — a first encounter with NGC 5112

Start with the simplest possible case. Write down what NGC 5112 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 5112 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 5112 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 5112

In research: NGC 5112 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 5112 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 5112 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1835, Barred spiral galaxies, Barred spiral galaxy stubs, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 5112 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.
