WASP-62

WASP-62 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 WASP-62 rather than just read about it. In short: WASP-62, formally named Naledi, is a single star about 573 light-years (176 parsecs) away in the constellation Dorado. It is an F-class main-sequence star, orbited by a planet, WASP-62b.

Key takeaways

WASP-62 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect WASP-62 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of WASP-62 from memory before moving on to harder problems.

Reference excerpt

WASP-62, formally named Naledi, is a single star about 573 light-years (176 parsecs) away in the constellation Dorado. It is an F-class main-sequence star, orbited by a planet, WASP-62b. The age of WASP-62 is much younger than the Sun at 0.8±0.6 billion years, and it has a metal abundance similar to the Sun.

Nomenclature The designation WASP-62 indicates that this was the 62nd star found to have a planet by the Wide Angle Search for Planets. This was one of the systems selected to be named in the 2019 NameExoWorlds campaign during the 100th anniversary of the IAU, which assigned each country a star and planet to be named. This system was assigned to South Africa. The approved names were announced in December 2019. The star is named Naledi, which means star in several languages of South Africa, and the planet is named Krotoa after a Khoi translator during colonial times.

Planetary system

A transiting hot Jupiter exoplanet orbiting WASP-62 was discovered in 2012 by WASP-South at the South African Astronomical Observatory. The planet's equilibrium temperature is 1,440±30 K, but the measured average temperature is colder at 1,329.6±44.8 K. In 2020, a transmission spectrum indicated the atmosphere of WASP-62b is free of clouds. It contains sodium and possibly silicon hydrides. The planetary orbit is slightly misaligned to the equatorial plane of the star, with the misalignment angle equal to 19.4+5.1−4.9°. It is named Krotoa, after the Khoi interpreter of that name.

Worked examples

Example 1 — a first encounter with WASP-62

Start with the simplest possible case. Write down what WASP-62 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 WASP-62 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 WASP-62 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 WASP-62

In research: WASP-62 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 WASP-62 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: WASP-62 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dorado, Durchmusterung objects, F-type main-sequence stars, so understanding it makes those chapters shorter.
In everyday life: Look for WASP-62 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 WASP-62 in simple terms?

WASP-62, formally named Naledi, is a single star about 573 light-years (176 parsecs) away in the constellation Dorado. It is an F-class main-sequence star, orbited by a planet, WASP-62b.

Why does WASP-62 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 WASP-62?

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.
