Aurigids
Aurigids is a meteor shower occurring primarily within September. The comet Kiess (C/1911 N1) is the source of the material that causes the meteors. The comet's orbital period is stated as approximately 1800 to 2000 years, with showers observed in the years 1935, '86, '94 and 2007 . α & δ The Alpha were discovered by C. Hoffmeister and A. Teichgraeber, during the night of 31 August 1935. See also * Carl Clarence Kiess * Delta Aurigids * List of meteor showers Named meteor showers recur at approximately the same dates each year.

Auriga (constellation)
Auriga is a constellation in the northern celestial hemisphere. It is one of the 88 modern constellations; it was among the 48 constellations listed by the 2nd-century astronomer Ptolemy. Its name is Latin for '(the) charioteer', associating it with various mythological beings, including Erichthonius and Myrtilus. Auriga is most prominent during winter evenings in the northern Hemisphere, as are five other constellations that have stars in the Winter Hexagon asterism. Because of its northern declination, Auriga is only visible in its entirety as far south as -34°; for observers farther south it lies partially or fully below the horizon. A large constellation, with an area of 657 square degrees, it is half the size of the largest, Hydra. Its brightest star, Capella, is an unusual multiple star system among the brightest stars in the night sky. Beta Aurigae is an interesting variable star in the constellation; Epsilon Aurigae, a nearby eclipsing binary with an unusually l ...

List Of Meteor Showers
Named meteor showers recur at approximately the same dates each year. They appear to radiate from a certain point in the sky, known as the radiant, and vary in the speed, frequency and brightness of the meteors. As of November 2019, there are 112 established meteor showers. Table of meteor showers Dates are given for 2022.https://www.amsmeteors.org/meteor-showers/2020-meteor-shower-list/ 2022 IMO list at amsmeteors.org The dates will vary from year to year due to the leap year cycle. This list includes showers with radiants in both the northern and southern hemispheres. There is some overlap, but generally showers whose radiants have positive declinations are best seen from the northern hemisphere, and those with negative declinations are best observed from the southern hemisphere.

Meteor Shower
A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never hit the Earth's surface. Very intense or unusual meteor showers are known as meteor outbursts and meteor storms, which produce at least 1,000 meteors an hour, most notably from the Leonids. The Meteor Data Centre lists over 900 suspected meteor showers of which about 100 are well established. Several organizations point to viewing opportunities on the Internet. NASA maintains a daily map of active meteor showers. Historical developments A meteor shower in August 1583 was recorded in the Timbuktu manuscripts.Abraham, Curtis"Stars of the Sahara" ''New Scientist'', issue 2617,15 August 2007, page 39–41 I ...

Kiess (C/1911 N1)
1788 Kiess, provisional designation , is a carbonaceous Themistian asteroid from the outer region of the asteroid belt, approximately 20 kilometers in diameter. It was discovered on 25 July 1952, by the Indiana Asteroid Program at the U.S. Goethe Link Observatory near Brooklyn, Indiana, United States, and later named after astronomer Carl Kiess. Orbit and classification The C-type asteroid is a member of the Themis family, a dynamical family of outer-belt asteroids with nearly coplanar ecliptical orbits. The asteroid orbits the Sun in the outer main-belt at a distance of 2.6–3.6 AU once every 5 years and 6 months (2,010 days). Its orbit has an eccentricity of 0.15 and an inclination of 1 ° with respect to the ecliptic. ''Kiess'' was first identified as at Algiers Observatory in 1935. Its observation arc begins with its official discovery observation. Physical characteristics Rotation period In 2010, two rotational lightcurves were obtained from photome ...

Orbital Period
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars. For celestial objects in general, the sidereal period ( sidereal year) is referred to by the orbital period, determined by a 360° revolution of one body around its primary, e.g. Earth around the Sun, relative to the fixed stars projected in the sky. Orbital periods can be defined in several ways. The tropical period is more particularly about the position of the parent star. It is the basis for the solar year, and respectively the calendar year. The synodic period incorporates not only the orbital relation to the parent star, but also to other celestial objects, making it not a mere different approach to the orbit of an object around its parent, but a period of orbital relations wit ...

Carl Clarence Kiess
Carl Clarence Kiess (October 18, 1887 – October 16, 1967) was an American astronomer. His main contributions was in the study of solar and stellar spectra. Kiess was born in Fort Wayne, Indiana. He earned a BA in astronomy from Indiana University in 1910 and a PhD from the University of California, Berkeley in 1913. After teaching at the University of Missouri, Pomona College, and the University of Michigan, Kiess took a position at the National Bureau of Standards in 1917. He retired from the bureau in 1957. While working at the Lick Observatory on July 6, 1911, Kiess discovered comet C/1911 N1, which was named after him. A lunar crater and the asteroid 1788 were also named after him. Kiess was a recipient of an honorary doctorate degree from the Indiana University Indiana University (IU) is a system of public universities in the U.S. state of Indiana.

Footnotes
A note is a string of text placed at the bottom of a page in a book or document or at the end of a chapter, volume, or the whole text. The note can provide an author's comments on the main text or citations of a reference work in support of the text. Footnotes are notes at the foot of the page while endnotes are collected under a separate heading at the end of a chapter, volume, or entire work. Unlike footnotes, endnotes have the advantage of not affecting the layout of the main text, but may cause inconvenience to readers who have to move back and forth between the main text and the endnotes. In some editions of the Bible, notes are placed in a narrow column in the middle of each page between two columns of biblical text. Numbering and symbols In English, a footnote or endnote is normally flagged by a superscripted number immediately following that portion of the text the note references, each such footnote being numbered sequentially. Occasionally, a number between bracke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
