Schelte J. Bus

Schelte J. Bus 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 Schelte J. Bus rather than just read about it. In short: Schelte John "Bobby" Bus (born 1956) is an American astronomer and discoverer of minor planets at the Institute for Astronomy of the University of Hawaiʻi and deputy director of NASA's Infrared Telescope Facility (IRTF) at the Mauna Kea Observatory in Hawaii, United States. Biography Bus graduated in 1979 from California Institute of Technology with a BS.

Key takeaways

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

Reference excerpt

Schelte John "Bobby" Bus (born 1956) is an American astronomer and discoverer of minor planets at the Institute for Astronomy of the University of Hawaiʻi and deputy director of NASA's Infrared Telescope Facility (IRTF) at the Mauna Kea Observatory in Hawaii, United States.

Biography Bus graduated in 1979 from California Institute of Technology with a BS. In 1999, he received his Ph.D. from the Massachusetts Institute of Technology. With MIT's Richard Binzel, Bus further added to the knowledge about main-belt asteroids in a spectroscopic survey published in 2002. This project was known as Small Main-Belt Asteroid Spectroscopic Survey, Phase II or SMASSII, which built on a previous survey of the main-belt asteroids. The visible-wavelength (435–925 nanometers) spectra data was gathered between August 1993 and March 1999. During his studies, he worked under the supervision of Eugene Shoemaker. As of 2017, Bus is an Astronomer at the University of Hawaii Institute for Astronomy and deputy director of NASA's Infrared Telescope Facility IRTF.

Awards and honors Asteroid 3254 Bus, which was discovered in 1982 by Edward Bowell, was named in his honor.

Discoveries

In 1981, Bus discovered periodic comet 87P/Bus. Since 1975, he has also discovered or co-discovered over a thousand asteroids, including: an Apollo asteroid, 2135 Aristaeus, which will come within 13 lunar distances of the Earth on 30 March 2147; an Amor asteroid; and more than 40 Jupiter trojans. The first of these was 3240 Laocoon, which he co-discovered with Eleanor F. Helin. Bus was also the discoverer of asteroids 5020 Asimov and 4923 Clarke, named after two science fiction writers (see 5020 and 4923).

Worked examples

Example 1 — a first encounter with Schelte J. Bus

Start with the simplest possible case. Write down what Schelte J. Bus 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 Schelte J. Bus 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 Schelte J. Bus 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 Schelte J. Bus

In research: Schelte J. Bus 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 Schelte J. Bus 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: Schelte J. Bus is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 20th-century American astronomers, 21st-century American astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Schelte J. Bus 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.
