Laevens 3

Laevens 3 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 Laevens 3 rather than just read about it. In short: Laevens 3 is a globular cluster in the constellation of Delphinus. It belongs to the Milky Way but orbits far from the centre.

Key takeaways

Laevens 3 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Laevens 3 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Laevens 3 from memory before moving on to harder problems.

Reference excerpt

Laevens 3 is a globular cluster in the constellation of Delphinus. It belongs to the Milky Way but orbits far from the centre. The cluster is named after Benjamin P. M. Laevens, the discoverer. It was first observed in 2015 using Pan-STARRS 1. It is located 210,000 light years from Earth in the outer galactic halo. Its orbit takes it as close as 133,000 ly from galactic centre out to 279,000 ly. The half light diameter is only 37 light years. The metallicity is −1.8 dex. It is about 13 billion years old, and its brightness is equivalent to 1,125 Suns.

Worked examples

Example 1 — a first encounter with Laevens 3

Start with the simplest possible case. Write down what Laevens 3 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 Laevens 3 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 Laevens 3 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 Laevens 3

In research: Laevens 3 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 Laevens 3 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: Laevens 3 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Delphinus, Globular clusters, Star cluster stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Laevens 3 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.
