Kepler-445

Kepler-445 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-445 rather than just read about it. In short: Kepler-445 is a red dwarf star located 401 light-years (123 parsecs) away in the constellation Cygnus. It hosts three known exoplanets, discovered by the transit method using data from the Kepler space telescope and confirmed in 2015.

Key takeaways

Kepler-445 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-445 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kepler-445 from memory before moving on to harder problems.

Reference excerpt

Kepler-445 is a red dwarf star located 401 light-years (123 parsecs) away in the constellation Cygnus. It hosts three known exoplanets, discovered by the transit method using data from the Kepler space telescope and confirmed in 2015. None of the planets orbit within the habitable zone.

Planetary system Kepler-445b, c, and d orbit Kepler-445 every 3, 5, and 8 days, and have equilibrium temperatures of 401 K (128 °C; 262 °F), 341 K (68 °C; 154 °F), and 305 K (32 °C; 89 °F), respectively. With a radius of 2.72 times that of Earth, Kepler-445c is likely a mini-Neptune with a volatile-rich composition, and has been compared to GJ 1214 b. Kepler-445d is only slightly larger than the Earth, with a radius of 1.33 R🜨.

Worked examples

Example 1 — a first encounter with Kepler-445

Start with the simplest possible case. Write down what Kepler-445 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-445 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-445 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-445

In research: Kepler-445 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-445 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-445 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cygnus (constellation), Kepler objects of interest, M-type main-sequence stars, so understanding it makes those chapters shorter.
In everyday life: Look for Kepler-445 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-445 in simple terms?

Why does Kepler-445 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-445?

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.
