Hipparchus (Martian crater)

Hipparchus (Martian 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 Hipparchus (Martian crater) rather than just read about it. In short: Hipparchus is an impact crater in the Phaethontis quadrangle of Mars, located at 44.8° S latitude and 151.4° W longitude. It is 93 kilometers (58 miles) in diameter.

Key takeaways

Hipparchus (Martian 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 Hipparchus (Martian crater) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hipparchus (Martian crater) from memory before moving on to harder problems.

Reference excerpt

Hipparchus is an impact crater in the Phaethontis quadrangle of Mars, located at 44.8° S latitude and 151.4° W longitude. It is 93 kilometers (58 miles) in diameter. It was named after the ancient Greek astronomer Hipparchus in 1973.

Channels There is abundant evidence that water once flowed in river valleys on Mars. Images of curved channels have been seen in images from Mars spacecraft dating back to the early seventies with the Mariner 9 orbiter. Indeed, a study published in June 2017, calculated that the volume of water needed to carve all the channels on Mars was even larger than the proposed ocean that the planet may have had. Water was probably recycled many times from the ocean to rainfall around Mars. Some of the pictures on this page show channels in Hipparchus Crater.

Worked examples

Example 1 — a first encounter with Hipparchus (Martian crater)

Start with the simplest possible case. Write down what Hipparchus (Martian 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 Hipparchus (Martian 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 Hipparchus (Martian 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 Hipparchus (Martian crater)

In research: Hipparchus (Martian 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 Hipparchus (Martian 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: Hipparchus (Martian crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on Mars, Mars crater stubs, Phaethontis quadrangle, so understanding it makes those chapters shorter.
In everyday life: Look for Hipparchus (Martian 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.
