Kepler-124b

Kepler-124b 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-124b rather than just read about it. In short: Kepler-124b is an extrasolar planet discovered in 2014. It is located 359 parsecs (1,170 light-years) from Earth, orbiting the unclassified star Kepler-124 in the constellation Draco.

Key takeaways

Kepler-124b 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-124b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kepler-124b from memory before moving on to harder problems.

Reference excerpt

Kepler-124b is an extrasolar planet discovered in 2014. It is located 359 parsecs (1,170 light-years) from Earth, orbiting the unclassified star Kepler-124 in the constellation Draco. Within the Kepler-124 system (KOI-241) there are three known planets, Kepler-124b being both the smallest and closest to its parent star.

Characteristics Kepler-124b is located 359 parsecs (1,170 light-years) from Earth orbiting the star Kepler-124. Both Kepler-124b and its host star are smaller than our own planet and star, respectively; Kepler-124b is estimated to be 0.729±0.045 Earth radii (0.065±0.004 Jupiter radii), and its parent star Kepler-124 is estimated to be 68.7% of the mass the Sun, approximately 0.636±0.030 solar radii. It is the smallest discovered planet in the Kepler-124 system, and has the closest orbit of the three known planets. Kepler-124b orbits 96% closer to its star than Earth (approximately 3 Earth days), which in the Kepler-124 system is inside the inner limit of the star's habitable zone.

Discovery Like many Exoplanets discovered by the Kepler telescope, Kepler-124b was found using the transit method. The transit method utilizes the high magnification and numerous instruments on the Kepler telescope to detect slight fluctuations in brightness of a star being observed. These dips can indicate the presence planet and determine certain parameters of it as well. Kepler-124b was initially only a planet candidate but was later confirmed as an exoplanet; a statistical analysis by a team at NASA Ames Research Center validated the existence of Kepler-124b with 99% assurance, along with Kepler-124c and Kepler-124d. Although scientists are very confident about some of Kepler-124b's parameters, many are still unknown.

Worked examples

Example 1 — a first encounter with Kepler-124b

Start with the simplest possible case. Write down what Kepler-124b 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-124b 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-124b 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-124b

In research: Kepler-124b 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-124b 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-124b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Draco (constellation), Exoplanets discovered by the Kepler space telescope, Exoplanets discovered in 2014, so understanding it makes those chapters shorter.
In everyday life: Look for Kepler-124b 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.
