OGLE-2016-BLG-1195Lb

OGLE-2016-BLG-1195Lb 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-2016-BLG-1195Lb rather than just read about it. In short: OGLE-2016-BLG-1195Lb is an extrasolar planet located about 22,000 light-years from Earth, in the galactic bulge, orbiting the 0.57±0.06 M☉ star OGLE-2016-BLG-1195L, discovered in 2017. The planet was detected using gravitational microlensing techniques managed by the Korea Astronomy and Space Science Institute and the Spitzer Space Telescope.

Key takeaways

OGLE-2016-BLG-1195Lb 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-2016-BLG-1195Lb to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

OGLE-2016-BLG-1195Lb is an extrasolar planet located about 22,000 light-years from Earth, in the galactic bulge, orbiting the 0.57±0.06 M☉ star OGLE-2016-BLG-1195L, discovered in 2017. The planet was detected using gravitational microlensing techniques managed by the Korea Astronomy and Space Science Institute and the Spitzer Space Telescope. Initially, it was believed the planet has a mass similar to Earth and is located about the same distance from its host star as the Earth is from the Sun, although it was expected to be much colder. In 2023, the planetary mass estimate was significantly increased to 9.91±1.61 M🜨, resulting in it likely being a Neptune-like ice giant planet.

In popular culture The planet has been referred to as Hoth due to its resemblance (before 2023 parameters update) to the planet with the same name from the Star Wars franchise. A similar exoplanet, OGLE-2005-BLG-390Lb, has also been compared to Hoth, by NASA in this instance.

Worked examples

Example 1 — a first encounter with OGLE-2016-BLG-1195Lb

Start with the simplest possible case. Write down what OGLE-2016-BLG-1195Lb 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-2016-BLG-1195Lb 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-2016-BLG-1195Lb 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-2016-BLG-1195Lb

In research: OGLE-2016-BLG-1195Lb 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-2016-BLG-1195Lb 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-2016-BLG-1195Lb is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanet stubs, Exoplanets detected by microlensing, Exoplanets discovered in 2017, so understanding it makes those chapters shorter.
In everyday life: Look for OGLE-2016-BLG-1195Lb 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.
