HD 16175 b

HD 16175 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 16175 b rather than just read about it. In short: HD 16175 b is an exoplanet located approximately 195.7 light-years away in the constellation of Andromeda, orbiting the star HD 16175. This planet has a minimum mass 4.8 times that of Jupiter; the true mass was initially unknown since the inclination of the orbit was unknown.

Key takeaways

HD 16175 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 16175 b to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of HD 16175 b from memory before moving on to harder problems.

Reference excerpt

HD 16175 b is an exoplanet located approximately 195.7 light-years away in the constellation of Andromeda, orbiting the star HD 16175. This planet has a minimum mass 4.8 times that of Jupiter; the true mass was initially unknown since the inclination of the orbit was unknown. This planet orbits at about 2.2 astronomical units, taking 2.73 years to revolve around the star. The orbit of the planet is highly elliptical with an eccentricity of 0.64. In 2023, the inclination and true mass of HD 16175 b were determined via astrometry. The planet HD 16175 b is named Abol. The name was selected in the NameExoWorlds campaign by Ethiopia, during the 100th anniversary of the IAU. Abol is the first of three rounds of coffee in the Ethiopian traditional coffee ceremony.

Discovery The discovery was made using radial velocity measurements taken between November 2004 and March 2009 with the Coudé Auxiliary and C. Donald Shane telescopes at Lick Observatory.

Worked examples

Example 1 — a first encounter with HD 16175 b

Start with the simplest possible case. Write down what HD 16175 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 16175 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 16175 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 16175 b

In research: HD 16175 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 16175 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 16175 b is common in secondary-school and first-year university syllabi. It links to neighbouring topics Andromeda (constellation), Exoplanet stubs, Exoplanets detected by astrometry, so understanding it makes those chapters shorter.
In everyday life: Look for HD 16175 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.
