Phillips (lunar crater)

Phillips (lunar crater) 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 Phillips (lunar crater) rather than just read about it. In short: Phillips is a lunar impact crater that is located in the vicinity of the Moon's east-southeastern limb, named after British geologist John Phillips. A larger walled plain called Humboldt lies across the eastern rim of Phillips, and its outer rampart covers nearly half the interior floor.

Key takeaways

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

Reference excerpt

Phillips is a lunar impact crater that is located in the vicinity of the Moon's east-southeastern limb, named after British geologist John Phillips. A larger walled plain called Humboldt lies across the eastern rim of Phillips, and its outer rampart covers nearly half the interior floor. The surviving rim is eroded in places, and not quite circular.

The northern end of the crater's rim forms an outward-projecting bend, and the inner wall is diminished along that side. There is a small circular crater along the western rim. The interior floor is irregular in places, with a central ridge near the midpoint. To the southwest of Phillips lies the crater Legendre.

Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Phillips.

Worked examples

Example 1 — a first encounter with Phillips (lunar crater)

Start with the simplest possible case. Write down what Phillips (lunar crater) 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 Phillips (lunar crater) 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 Phillips (lunar crater) 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 Phillips (lunar crater)

In research
Phillips (lunar crater) 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 Phillips (lunar crater) 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
Phillips (lunar crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ21 quadrangle, so understanding it makes those chapters shorter.
In everyday life
Look for Phillips (lunar crater) 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.
