Around forty comets have had their orbits calculated based entirely on ancient Chinese records. [2] Of the well known comets, besides Halley, Brian G. Marsden suggested, based on Chinese and other ancient observations, that the Great Comet of 1106 was a previous apparition of Comet Ikeya–Seki. [14]
Little is known of what people thought about comets before Aristotle, who observed his eponymous comet, and most of what is known comes secondhand.From cuneiform astronomical tablets, and works by Aristotle, Diodorus Siculus, Seneca, and one attributed to Plutarch but now thought to be Aetius, it is observed that ancient philosophers divided themselves into two main camps.
The Divination by Astrological and Meteorological Phenomena (Chinese: 天文氣象雜占; pinyin: Tiān Wén Qì Xiàng Zá Zhàn), also known as Book of Silk is an ancient astronomy silk manuscript compiled by Chinese astronomers of the Western Han dynasty (202 BC – 9 AD) and found in the Mawangdui of Changsha, Hunan, China in 1973.
Heinrich Kreutz was a German astronomer, [11] who claimed that the orbits of several sungrazing comets were related and likely produced when a large Sun-grazing comet fragmented hundreds of years previously. That group, known as the Kreutz Sungrazers, has produced some of the brightest comets ever observed, including X/1106 C1 and Comet Ikeya ...

In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet that has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), "I" for an interstellar object, or "A" for an object that was either mistakenly ...
Scientists in Germany have observed a comet-like object in a distant galaxy that is similar in composition to the famed Halley's comet -- just a LOT bigger. Astronomers discover comet 100,000 ...
Periodic comets usually have elongated elliptical orbits, and usually return to the vicinity of the Sun after a number of decades. The official names of non-periodic comets begin with a "C"; the names of periodic comets begin with "P" or a number followed by "P". Comets that have been lost or disappeared have names with a "D". Comets whose ...
