Comet Hale–Bopp (formally designated C/1995 O1) is a long-period comet that was one of the most widely observed of the 20th century and one of the brightest seen for many decades. [11] [12] [13] Alan Hale and Thomas Bopp discovered Comet Hale–Bopp separately on July 23, 1995, before it became visible to the naked eye.
Halley's calculations enabled the comet's earlier appearances to be found in the historical record. The following table sets out the astronomical designations for every apparition of Halley's Comet from 240 BC, the earliest documented sighting. [7] [167] In the designations, "1P/" refers to Halley's Comet; the first periodic comet discovered.
The famous Halley’s comet is about halfway through its roughly 76-year orbit of the sun, having reached its farthest point from its host star in December 2023. The comet won’t be visible in ...

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 ...
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 ...
On September 26 the comet made its closet approach to Earth at a distance of about 1.15 AU; for a great comet this distance is unusually large — only two other known great comets failed to come closer than 1 AU to Earth — namely, the Great Comet of 1811 and Comet Hale-Bopp.
