HIP 116454 b

HIP 116454 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 HIP 116454 b rather than just read about it. In short: HIP 116454 b, or K2-2 b, is an exoplanet orbiting the star HIP 116454, 62 parsecs (201 ly) from Earth toward the constellation Pisces. It is 32,000 kilometres (20,000 mi) in diameter and 12 times as massive as Earth.

Key takeaways

HIP 116454 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 HIP 116454 b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HIP 116454 b from memory before moving on to harder problems.

Reference excerpt

HIP 116454 b, or K2-2 b, is an exoplanet orbiting the star HIP 116454, 62 parsecs (201 ly) from Earth toward the constellation Pisces. It is 32,000 kilometres (20,000 mi) in diameter and 12 times as massive as Earth. It was discovered by the NASA Kepler spacecraft, and is the first exoplanet discovered during Kepler's K2 mission. The discovery was announced on December 18, 2014. HIP 116454 b does not have a normal Kepler designation due to not being located in the original Kepler field. HIP 116454 b was discovered in a Kepler engineering data set which was collected in preparation of the first full K2 campaign. Unlike most other Kepler planets, only a single transit event of HIP 116454 b was detected, requiring follow-up radial velocity measurements by the HARPS-N spectrograph and photometric measurements by the Canadian MOST satellite. Physical characteristics of HIP 116454 b are expected to be similar to Kepler-68b, being somewhere between super-Earth and mini-Neptune.

Worked examples

Example 1 — a first encounter with HIP 116454 b

Start with the simplest possible case. Write down what HIP 116454 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 HIP 116454 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 HIP 116454 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 HIP 116454 b

In research: HIP 116454 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 HIP 116454 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: HIP 116454 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Exoplanet stubs, Exoplanets discovered by K2, Exoplanets discovered in 2014, so understanding it makes those chapters shorter.
In everyday life: Look for HIP 116454 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.
