HD 11964 b

HD 11964 b 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 HD 11964 b rather than just read about it. In short: HD 11964 b is an extrasolar planet, a gas giant like Jupiter approximately 110 light-years away in the constellation of Cetus. The planet orbits the yellow subgiant star HD 11964 in a nearly circular orbit, taking over 5 years to complete a revolution around the star at a distance of 3.34 astronomical units.

Key takeaways

HD 11964 b belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect HD 11964 b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 11964 b from memory before moving on to harder problems.

Reference excerpt

HD 11964 b is an extrasolar planet, a gas giant like Jupiter approximately 110 light-years away in the constellation of Cetus. The planet orbits the yellow subgiant star HD 11964 in a nearly circular orbit, taking over 5 years to complete a revolution around the star at a distance of 3.34 astronomical units. The planet was discovered in 2005 and published as part of the Catalog of Nearby Exoplanets, (or more like the Catalog of Far Away Exoplanets because all exoplanets are far away) under the designation HD 11964 b. However, since that time there has been confusion as to the designations of the planets in the HD 11964 system, leading to some sources designating this planet as "HD 11964 c". In a recent review of the properties of multi-planet extrasolar planetary systems, the discovery team has stated that the correct designation for this planet is HD 11964 b.

Worked examples

Example 1 — a first encounter with HD 11964 b

Start with the simplest possible case. Write down what HD 11964 b 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 HD 11964 b 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 HD 11964 b 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 HD 11964 b

In research: HD 11964 b 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 HD 11964 b 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: HD 11964 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cetus (constellation), Exoplanet stubs, Exoplanets detected by radial velocity, so understanding it makes those chapters shorter.
In everyday life: Look for HD 11964 b 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.
