Kepler-296d

Kepler-296d 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 Kepler-296d rather than just read about it. In short: Kepler-296d is an exoplanet orbiting the M-dwarf star Kepler-296, located in the constellation Draco. It was discovered in 2014 by the Kepler space telescope using the transit method.

Key takeaways

Kepler-296d belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kepler-296d to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kepler-296d from memory before moving on to harder problems.

Reference excerpt

Kepler-296d is an exoplanet orbiting the M-dwarf star Kepler-296, located in the constellation Draco. It was discovered in 2014 by the Kepler space telescope using the transit method.

Characteristics Kepler-296d has a radius approximately 2.09 times that of Earth and a mass estimated at 5.02 Earth masses, placing it in the category of Neptune-like exoplanets. The planet orbits its host star every 19.9 days at a distance of approximately 0.118 AU. Its orbit has an eccentricity of less than 0.33.

Host Star The host star, Kepler-296, is an M-type dwarf. These stars are cooler and smaller than the Sun, and often host multiple exoplanets. Kepler-296 is known to host at least five planets.

Discovery Kepler-296d was identified in 2014 as part of the data collected by NASA's Kepler space telescope, which monitored the brightness of over 150,000 stars to detect periodic dips in light indicative of planetary transits. The detection of Kepler-296d was achieved through the transit method, wherein a planet passes between its host star and the observer, causing a measurable decrease in the star’s apparent brightness.

Worked examples

Example 1 — a first encounter with Kepler-296d

Start with the simplest possible case. Write down what Kepler-296d 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 Kepler-296d 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 Kepler-296d 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 Kepler-296d

In research: Kepler-296d 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 Kepler-296d 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: Kepler-296d is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanets discovered by the Kepler space telescope, Exoplanets discovered in 2014, Kepler-296, so understanding it makes those chapters shorter.
In everyday life: Look for Kepler-296d 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.
