    The comet is currently moving through the Southern hemisphere and will cross the celestial equator (yellow vertical line) in 2032. The apparent loops in the comet's path are caused by the annual motion of the Earth around the Sun. With a current declination of −47° below the celestial equator, C/2014 UN 271 is best seen from the Southern ...

    en.wikipedia.org/wiki/List_of_comets_by_type

    This is a list of comets (bodies that travel in elliptical, parabolic, and sometimes hyperbolic orbits and display a tail behind them) listed by type. Comets are sorted into four categories: periodic comets (e.g. Halley's Comet), non-periodic comets (e.g. Comet Hale–Bopp), comets with no meaningful orbit (the Great Comet of 1106), and lost comets (), displayed as either P (periodic), C (non ...

    A great comet appeared in the sky above Europe on 1577 AD. Tycho Brahe decided to try and estimate the distance to this comet by measuring its parallax, the effect whereby the position or direction of an object appears to differ when viewed from different positions. He proposed that comets (like planets) return to their respective positions in ...

    Comet vintages are years during which an astronomical event, involving generally a "Great Comet", occurs prior to harvest. Throughout the history of wine , winemakers have attributed successful vintages and ideal weather conditions to the unexplained effects caused by the comets . [ 1 ]

    en.wikipedia.org/wiki/27P/Crommelin

    Comet Crommelin, also known as Comet Pons-Coggia-Winnecke-Forbes, is a periodic comet with an orbital period of almost 28 years. It fits the classical definition of a Halley-type comet with (20 years < period < 200 years). It is named after the British astronomer Andrew C. D. Crommelin who calculated its orbit in 1930.

    C/2016 R2 (PanSTARRS) is a comet, discovered using the Pan-STARRS telescopes on September 7, 2016. The comet attracted attention from many astronomers as it approached its closest point to the Sun in May 2018. [4] It has been observed to have a very complex tail, which has been suggested to be due to a fast rotation period of the nucleus.
