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.
Heinrich Kreutz was a German astronomer 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. [11] That group, known as the Kreutz Sungrazers, has produced some of the brightest comets ever observed, including X/1106 C1 and Comet Ikeya ...
The Chinese records are not only the most extensive from ancient times, they are also the most accurate, often to within half a degree of right ascension. Western measurements did not overtake them for accuracy until the fifteenth century: in 1456 AD Paolo Toscanelli tracked the progress of Halley's Comet to within a fraction of a degree. [3]

Comets whose aphelia are near a major planet's orbit are called its "family". [81] Such families are thought to arise from the planet capturing formerly long-period comets into shorter orbits. [82] At the shorter orbital period extreme, Encke's Comet has an orbit that does not reach the orbit of Jupiter, and is known as an Encke-type comet.
In ancient and medieval times, only objects visible to the naked eye—the Sun, the Moon, the five classical planets, and comets, along with phenomena now known to take place in Earth's atmosphere, like meteors and aurorae—were known. [dubious – discuss] Ancient

The confirmation of the comet's return was the first time anything other than planets had been shown to orbit the Sun. [36] It was also one of the earliest successful tests of Newtonian physics, and a clear demonstration of its explanatory power. [37] The comet was first named in Halley's honour by French astronomer Nicolas-Louis de Lacaille in ...
