    Comet HaleBopp (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. [citation needed] Alan Hale and Thomas Bopp discovered Comet HaleBopp separately on July 23, 1995, before it became visible to the naked eye.

    The following list is of comets with very long orbital periods, defined as between 200 and 1000 years.These comets come from the Kuiper belt and scattered disk, beyond the orbit of Pluto, with possible origins in the Oort cloud for many.

  4. List of comets by type - Wikipedia

    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 HaleBopp), comets with no meaningful orbit (the Great Comet of 1106), and lost comets (), displayed as either P (periodic), C (non ...

  5. List of periodic comets - Wikipedia

    en.wikipedia.org/wiki/List_of_periodic_comets

    Periodic comets (also known as short-period comets) are comets with orbital periods of less than 200 years or that have been observed during more than a single perihelion passage [1] (e.g. 153P/Ikeya–Zhang). "Periodic comet" is also sometimes used to mean any comet with a periodic orbit, even if greater than 200 years.

    For example, Comet HaleBopp's designation is C/1995 O1. After their second observed perihelion passage, designations of periodic comets are given an additional prefix number, indicating the order of their discovery. [7] Halley's Comet, the first comet identified as periodic, has the systematic designation 1P/1682 Q1.

    The comet temporarily upstaged the much anticipated Comet HaleBopp, which was approaching the inner Solar System at the time. Hyakutake is a long-period comet that passed perihelion on 1 May 1996.

    A minor outburst took place on 6 February, which was also observed in infrared. The comet was last observed on 4 May 1970. [6] C/1969 T1 was the very first comet observed by Alan Hale (who later became the co-discoverer of Comet Hale-Bopp), at the time the comet faded as a 5th-magnitude object on February 2, 1970. [8]
