He's best known for his discovery and co-discovery of 10 comets since the 1980s, among them 79P/du Toit-Hartley, 80P/Peters–Hartley, 100P/Hartley, 110P/Hartley, and C/1984 W2.[3][5] Unfortunately for Hartley, in 2002, "the Anglo-Australian Observatory retrofitted its Schmidt to perform multi-object spectroscopy, essentially halting all astrophotography with the telescope and ending any future possibility for comet discovery".[5] In November 2010, he visited NASA's Jet Propulsion Laboratory facility in California to witness the EPOXI mission flyby of comet 103P/Hartley on 4 November 2010.[7]Hartley is credited by the Minor Planet Center with the discovery of 3 asteroids made at the Siding Spring Observatory between 1996 and 1998, with {{mp|(21374) 1997 WS|22}} and {{mp|(65674) 1988 SM}} being near-Earth objects of the Amor group of asteroids. The outer main-belt asteroid 4768 Hartley was named in his honour, being deputy astronomer of the U.K. Schmidt telescope at Siding Spring, with which this minor planet was discovered.[3] Naming citation was published on 27 June 1991 ({{small|M.P.C. 18464}}).[10] References1. ^[https://www.bbc.com/news/science-environment-11674694 "Probe sweeps past 'space peanut'"].
