Task: Question Answering
Input (English): Context_1 : NGC 7016 is an elliptical or lenticular galaxy located about 480 million Light-years away from Earth in the constellation Capricornus. NGC 7016's calculated velocity is 11,046 km/s. NGC 7016 has an estimated diameter of about 140 thousand light years. NGC 7016 was discovered by American astronomer Francis Preserved Leavenworth on July 8, 1885. Context_2 : NGC 7301 is a barred spiral galaxy located around 308000000 ly away from Earth in the constellation Aquarius. It was discovered by American astronomer Francis Preserved Leavenworth In 1886. Context_3 : NGC 6380 is a globular cluster located in the constellation Scorpius. It was discovered by the British astronomer John Herschel on 29 June 1834. It is at a distance of about 35,500 light years away from earth. NGC 6380 was initially characterized as an open cluster, and given the designation Pişmiş 25, however later in 1950, the American astronomer A. David Thackeray found that it is actually a globular cluster. Context_4 : Messier 72 (also known as M72 or NGC 6981) is a globular cluster in the Aquarius constellation discovered by French astronomer Pierre Méchain on August 29, 1780. French astronomer Charles Messier looked for it on the following October 4, and included it in his catalog. Both decided that it was a faint nebula rather than a cluster. With a larger instrument, British astronomer John Herschel called it a bright "cluster of stars of a round figure". American astronomer Harlow Shapley noted a similarity to Messier 4 and Messier 12. Context_5 : NGC 6285 is an interacting spiral galaxy located in the constellation Draco. It is designated as S0-a in the galaxy morphological classification scheme and was discovered by the American astronomer Lewis A. Swift in 1886. NGC 6285 is located at about 262 million light years away from earth. NGC 6285 and NGC 6286 form a pair of interacting galaxies, with tidal distortions, categorized as Arp 293 in the Arp Atlas of Peculiar Galaxies<ref name="NASA/IPAC"> </ref> Context_6 : Francis Preserved Leavenworth (born September 3, 1858 in Mount Vernon, Indiana; died November 12, 1928; a.k.a. "Frank Leavenworth") was an American astronomer. He discovered many New General Catalogue objects together with Frank Muller and Ormond Stone. They used a telescope with a 66-cm aperture at the Leander McCormick Observatory at the University of Virginia in Charlottesville, Virginia. Context_7 : NGC 6286 is an interacting spiral galaxy located in the constellation Draco. It is designated as Sb/P in the galaxy morphological classification scheme and was discovered by the American astronomer Lewis A. Swift on 13 August 1885. NGC 6286 is located at about 252 million light years away from Earth. NGC 6286 and NGC 6285 form a pair of interacting galaxies, with tidal distortions, categorized as Arp 293 in the Arp Atlas of Peculiar Galaxies.<ref name="NASA/IPAC"> </ref> Context_8 : NGC 1614 is the "New General Catalogue" identifier for a spiral galaxy in the equatorial constellation of Eridanus. It was discovered on December 29, 1885 by American astronomer Lewis Swift, who described it in a shorthand notation as: pretty faint, small, round, a little brighter middle. The nebula was then catalogued by Danish-Irish astronomer J. L. E. Drayer in 1888. When direct photography became available, it was noted that this galaxy displayed some conspicuous peculiarities. American astronomer Halton Arp included it in his 1966 "Atlas of Peculiar Galaxies". In 1971, Swiss astronomer Fritz Zwicky described it as a "blue post-eruptive galaxy, compact patchy core, spiral plumes, long blue jet SSW".

NGC 7302 was discovered by British astronomer William Herschel on October 3, 1785 and was rediscovered by American astronomer Lewis Swift on August 8, 1896 and was listed in the IC catalogue as IC 5228. It is also part of a group of interatcing galaxies. Context_10 : NGC 4633 is an spiral galaxy located about 70 million light-years away in the constellation of Coma Berenices. It is interacting with the nearby galaxy NGC 4634. NGC 4633 was discovered by astronomer Edward Swift on April 27, 1887. It was rediscovered on November 23, 1900 by astronomer Arnold Schwassmann and was later listed as IC 3688. NGC 4633 is a member of the Virgo Cluster. fact_1 : NGC 7301 is a barred spiral galaxy located around 308000000 ly away from Earth in the constellation Aquarius. fact_2 :  It was discovered by American astronomer Francis Preserved Leavenworth In 1886. fact_3 : Francis Preserved Leavenworth (born September 3, 1858 in Mount Vernon, Indiana; died November 12, 1928; a.k.a. "Frank Leavenworth") was an American astronomer. Question: NGC 7301 was discovered by an American astronomer in what year?
