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.
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]
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.
Watch as a green comet flew past Earth for the first time in some 50,000 years before disappearing from our Solar System. The C/2022 E3 (ZTF) comet is so rare that woolly mammoths and saber ...
