John J. Kavelaars

John J. Kavelaars 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 John J. Kavelaars rather than just read about it. In short: J-John Kavelaars, better known as JJ Kavelaars (born 1966), is a Canadian astronomer who was part of a team that discovered several moons of Jupiter, Saturn, Uranus, and Neptune. He is also a discoverer of minor planets and an investigator on the extended New Horizons mission, having aided in the discovery of 486958 Arrokoth.

Key takeaways

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

Reference excerpt

J-John Kavelaars, better known as JJ Kavelaars (born 1966), is a Canadian astronomer who was part of a team that discovered several moons of Jupiter, Saturn, Uranus, and Neptune. He is also a discoverer of minor planets and an investigator on the extended New Horizons mission, having aided in the discovery of 486958 Arrokoth.

Biography

Kavelaars is a graduate of the Glencoe District High School in Glencoe, Ontario, the University of Guelph, and Queen's University, Kingston, Ontario. He is currently an astronomer at the Dominion Astrophysical Observatory in Victoria, B.C. In the course of his work, he has been responsible for the discovery of eleven satellites (moons) of Saturn, eight of Uranus, and four of Neptune, and a hundred or so minor planets. Kavelaars is the Coordinator of the Canada–France Ecliptic Plane Survey which is part of the Canada-France-Hawaii Telescope Legacy Survey "CFHTLS": a project dedicated to the discovery and tracking of objects in the outer Solar System.

Family JJ Kavelaars has two daughters, the eldest being Ruth Ann Margaret Kevelaars and the youngest being Catherine Frances Kevelaars. He is the brother of Canadian actress Ingrid Kavelaars and Canadian fencing athlete Monique Kavelaars.

Honors The asteroid 154660 Kavelaars was named in his honor on 1 June 2007 by his colleague David D. Balam. In 2022 Kavelaars was awarded the Canadian Astronomical Society Dunlap Award for Innovation in Astronomical Instrumentation and Software. This award recognized Kavelaars' contributions to the development and leadership of the Canadian Astronomy Data Centre, in particular the development of cloud-based astronomical data analysis using the CANFAR Science Platform. In 2022 Kavelaars was awarded the National Research Council Dan Wayner award for outstanding achievement in Science and Technology. This award was presented in recognition of Kavelaars' co-discovery of 486958 Arrokoth and contributions to the NASA's New Horizons encounter with that object.

Worked examples

Example 1 — a first encounter with John J. Kavelaars

Start with the simplest possible case. Write down what John J. Kavelaars 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 John J. Kavelaars 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 John J. Kavelaars 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 John J. Kavelaars

In research: John J. Kavelaars 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 John J. Kavelaars 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: John J. Kavelaars is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 births, 21st-century Canadian astronomers, Canadian people of Swedish descent, so understanding it makes those chapters shorter.
In everyday life: Look for John J. Kavelaars 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.
