Tacitus (crater)

Tacitus (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 Tacitus (crater) rather than just read about it. In short: Tacitus is a lunar impact crater located to the northwest of the crater Catharina, at the northern extension of the Rupes Altai ridge line. It was named after the 1st century Roman historian and writer Tacitus.

Key takeaways

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

Reference excerpt

Tacitus is a lunar impact crater located to the northwest of the crater Catharina, at the northern extension of the Rupes Altai ridge line. It was named after the 1st century Roman historian and writer Tacitus. Directly west is the crater Almanon, and to the northeast is Cyrillus. To the southeast of Tacitus is a long chain of craters named the Catena Abulfeda. This chain runs to the northwest from the eastern edge of the Rupes Altai, continuing for over 200 kilometers. The crater terminates a ridge which forms part of the Rupes Altai. The outer wall has a small rampart, and the interior surfaces are terraced. The rim outline has a slight polygonal outline. There is a low ridge on the crater floor running from the north wall.

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 Tacitus.

Worked examples

Example 1 — a first encounter with Tacitus (crater)

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

In research
Tacitus (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 Tacitus (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
Tacitus (crater) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Impact craters on the Moon, LQ20 quadrangle, Tacitus, so understanding it makes those chapters shorter.
In everyday life
Look for Tacitus (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.
