Thelxinoe (moon)

Thelxinoe (moon) 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 Thelxinoe (moon) rather than just read about it. In short: Thelxinoe , also known as Jupiter XLII, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S.

Key takeaways

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

Reference excerpt

Thelxinoe , also known as Jupiter XLII, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard in 2004 from pictures taken in 2003, and originally received the temporary designation S/2003 J 22. Thelxinoe is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 20,454 Mm in 597.607 days, at an inclination of 151° to the ecliptic (153° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2685. It was named in March 2005 after Thelxinoe, one of the four original Muses according to some Greek writers, and a daughter of Zeus (Jupiter) by Mnemosyne. Thelxinoe belongs to the Ananke group, retrograde irregular moons that orbit Jupiter between 19.3 and 22.7 million km, at inclinations of roughly 150°.

Worked examples

Example 1 — a first encounter with Thelxinoe (moon)

Start with the simplest possible case. Write down what Thelxinoe (moon) 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 Thelxinoe (moon) 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 Thelxinoe (moon) 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 Thelxinoe (moon)

In research: Thelxinoe (moon) 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 Thelxinoe (moon) 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: Thelxinoe (moon) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ananke group, Astronomical objects discovered in 2004, Discoveries by Scott S. Sheppard, so understanding it makes those chapters shorter.
In everyday life: Look for Thelxinoe (moon) 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.
