Kepler-19c

Kepler-19c 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-19c rather than just read about it. In short: Kepler-19c is an extra-solar planet orbiting the star Kepler-19 approximately 717 light years from Earth. Discovery The planet was discovered as a result of examinations of data from the previously discovered exoplanet, Kepler-19b.

Key takeaways

Kepler-19c 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-19c to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kepler-19c from memory before moving on to harder problems.

Reference excerpt

Kepler-19c is an extra-solar planet orbiting the star Kepler-19 approximately 717 light years from Earth.

Discovery The planet was discovered as a result of examinations of data from the previously discovered exoplanet, Kepler-19b. Timing variations in the orbital period of the first planet necessitated gravitational forces to be acting upon the planet, resulting from an additional body in the vicinity, acting to cause a variation of transition of five minutes per orbit. The lead author of the paper announcing the discovery was Sarah Ballard.

Worked examples

Example 1 — a first encounter with Kepler-19c

Start with the simplest possible case. Write down what Kepler-19c 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-19c 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-19c 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-19c

In research: Kepler-19c 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-19c 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-19c 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 2011, so understanding it makes those chapters shorter.
In everyday life: Look for Kepler-19c 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.

Frequently asked questions

What is Kepler-19c in simple terms?

Kepler-19c is an extra-solar planet orbiting the star Kepler-19 approximately 717 light years from Earth. Discovery The planet was discovered as a result of examinations of data from the previously discovered exoplanet, Kepler-19b.

Why does Kepler-19c matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Kepler-19c?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
