List of smallest exoplanets

List of smallest exoplanets 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 List of smallest exoplanets rather than just read about it. In short: Below is a list of the smallest exoplanets so far discovered, in terms of physical size, ordered by radius. List The sizes are listed in units of Earth radii (R🜨).

Key takeaways

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

Reference excerpt

Below is a list of the smallest exoplanets so far discovered, in terms of physical size, ordered by radius.

List

The sizes are listed in units of Earth radii (R🜨). All planets listed are smaller than Earth and up to 1 Earth radii. The NASA Exoplanet Archive is used as the main data source. Radii listed in italics are estimates.

Excluded objects Kepler-37e is listed with a radius of 0.37±0.18 R🜨 in the Exoplanet Archive based on KOI data, but the existence of this planet is doubtful, and assuming its existence, a 2023 study found a mass of 8.1±1.7 M🜨, inconsistent with such a small radius. KOI-6705.01, listed as a potential very small planet in the KOI dataset, was shown to be a false positive in 2016.

Candidate planets Below is a list of candidate planets below 0.7 R🜨. These planets have yet to be confirmed.

Worked examples

Example 1 — a first encounter with List of smallest exoplanets

Start with the simplest possible case. Write down what List of smallest exoplanets 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 List of smallest exoplanets 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 List of smallest exoplanets 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 List of smallest exoplanets

In research: List of smallest exoplanets 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 List of smallest exoplanets 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: List of smallest exoplanets is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of exoplanets, Smallest things, Sub-Earth exoplanets, so understanding it makes those chapters shorter.
In everyday life: Look for List of smallest exoplanets 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.
