OGLE-2006-BLG-109Lb

OGLE-2006-BLG-109Lb 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 OGLE-2006-BLG-109Lb rather than just read about it. In short: OGLE-2006-BLG-109Lb is an extrasolar planet approximately 4,920 light-years away in the constellation of Scorpius. The planet was detected orbiting the star OGLE-2006-BLG-109L in 2008 by a research team using Microlensing.

Key takeaways

OGLE-2006-BLG-109Lb belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect OGLE-2006-BLG-109Lb to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of OGLE-2006-BLG-109Lb from memory before moving on to harder problems.

Worked examples

Example 1 — a first encounter with OGLE-2006-BLG-109Lb

Start with the simplest possible case. Write down what OGLE-2006-BLG-109Lb 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 OGLE-2006-BLG-109Lb 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 OGLE-2006-BLG-109Lb 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 OGLE-2006-BLG-109Lb

In research: OGLE-2006-BLG-109Lb 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 OGLE-2006-BLG-109Lb 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: OGLE-2006-BLG-109Lb is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanet stubs, Exoplanets detected by microlensing, Exoplanets discovered in 2008, so understanding it makes those chapters shorter.
In everyday life: Look for OGLE-2006-BLG-109Lb 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.
