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 ...

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 ...
Scientists believe Comet 12P/Pons-Brooks boasts an enormous diameter of about 10.5 miles, and the last time it passed this close to Earth was in 1954. Extremely rare 'devil comet' expected to pass ...
