Phocaea family

Phocaea family is a science 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 Phocaea family rather than just read about it. In short: The Phocaea family ( foh-SEE-ə; adj. Phocaean; FIN: 701) is a collisional family of asteroids located between 2.25 and 2.5 AU in the inner region of the asteroid belt.

Key takeaways

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

Reference excerpt

The Phocaea family ( foh-SEE-ə; adj. Phocaean; FIN: 701) is a collisional family of asteroids located between 2.25 and 2.5 AU in the inner region of the asteroid belt. Phocaea asteroids are of stony S-type composition and have orbits with eccentricities greater than 0.1 and inclinations between 18 and 32°. The family has an estimated age of 2.2 billion years and derives its name from its most massive member, 25 Phocaea which is about 75 km in diameter. Several Phocaean asteroids are also Mars-crossers.

Phocaea family region The Phocaea family region contains other collisional families such as the recently identified carbonaceous, Tamara family, named after its potentially largest member 326 Tamara. The family has an estimated age of 264 million years. Several clumps around 290 Bruna (Bruna family), 1192 Prisma and 6246 Komurotoru, as well as (17628) 1996 FB5, (19536) 1999 JM4 and (26142) 1994 PL1 have also been detected.

Worked examples

Example 1 — a first encounter with Phocaea family

Start with the simplest possible case. Write down what Phocaea family claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Phocaea family 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 Phocaea family 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 Phocaea family

In research: Phocaea family appears in science 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 Phocaea family 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: Phocaea family is common in secondary-school and first-year university syllabi. It links to neighbouring topics Asteroid groups and families, Phocaea asteroids, so understanding it makes those chapters shorter.
In everyday life: Look for Phocaea family 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 Phocaea family in simple terms?

The Phocaea family ( foh-SEE-ə; adj. Phocaean; FIN: 701) is a collisional family of asteroids located between 2.25 and 2.5 AU in the inner region of the asteroid belt.

Why does Phocaea family matter?

Because it connects several science 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 Phocaea family?

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.
