Reference excerpt

OGLE-2016-BLG-0007(also known as MOA-2016-BLG-088L) is a Galactic bulge star believed to be of spectral type K, located approximately 14,020 light-years or 4,300 parsecs from Earth in the constellation Sagittarius.

Planetary system

The star OGLE-2016-BLG-0007L has one known planet, discovered in 2025 using the gravitational microlensing method. The object, named OGLE-2016-BLG-0007Lb, is a super-Earth with a mass of 1.32 M🜨 and is located at a distance of 10.1 astronomical units, similar to Saturn's distance from the Sun. The exoplanet's orbital period is approximately 39 years. The radius of OGLE-2016-BLG-0007Lb has not been measured, but it was estimated by the NASA Eyes on Exoplanets program to be 1.09 R🜨. Scientists believe this object is the core of a giant planet that did not have enough time to accumulate gas from the protoplanetary disk to become a gas giant similar to Jupiter or Saturn.

Worked examples

Example 1 — a first encounter with OGLE-2016-BLG-0007

Start with the simplest possible case. Write down what OGLE-2016-BLG-0007 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-0007 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-0007 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-0007

In research: OGLE-2016-BLG-0007 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-0007 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-0007 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Gravitational lensing, Planetary systems with one confirmed planet, Sagittarius (constellation), so understanding it makes those chapters shorter.
In everyday life: Look for OGLE-2016-BLG-0007 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.
