NGC 1701

NGC 1701 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 NGC 1701 rather than just read about it. In short: NGC 1701, also known as the Trekkie Galaxy, is a large unbarred spiral galaxy located in the constellation Caelum. Its speed relative to the cosmic microwave background is 5,836 ± 24 km/s, which corresponds to a Hubble distance of 86.1 ± 6.0 Mpc (~281 million ly).

Key takeaways

  • NGC 1701 belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect NGC 1701 to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of NGC 1701 from memory before moving on to harder problems.

Reference excerpt

NGC 1701, also known as the Trekkie Galaxy, is a large unbarred spiral galaxy located in the constellation Caelum. Its speed relative to the cosmic microwave background is 5,836 ± 24 km/s, which corresponds to a Hubble distance of 86.1 ± 6.0 Mpc (~281 million ly). It was discovered by British astronomer John Herschel on 6 November 1834. The luminosity class of NGC 1701 is II and it has a broad HI line. The galaxy's nickname is a reference to the registry of the fictional USS Enterprise (NCC-1701) from the Star Trek media franchise.

Supernova One supernova has been observed in NGC 1701:

SN 2026dpg (Type Ia-91T-like, mag. 16.949) was discovered by ATLAS on 18 February 2026.

Worked examples

Example 1 — a first encounter with NGC 1701

Start with the simplest possible case. Write down what NGC 1701 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 NGC 1701 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 NGC 1701 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 NGC 1701

In research
NGC 1701 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 NGC 1701 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
NGC 1701 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 1834, Caelum, Discoveries by John Herschel, so understanding it makes those chapters shorter.
In everyday life
Look for NGC 1701 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 NGC 1701 in simple terms?

NGC 1701, also known as the Trekkie Galaxy, is a large unbarred spiral galaxy located in the constellation Caelum. Its speed relative to the cosmic microwave background is 5,836 ± 24 km/s, which corresponds to a Hubble distance of 86.1 ± 6.0 Mpc (~281 million ly).

Why does NGC 1701 matter?

Because it connects several astronomy 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 NGC 1701?

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.
