P/2011 P1 (McNaught) was a Jupiter-family comet that passed extremely close to Jupiter on 4 December 2010 and disintegrated by 2012.[4] It was discovered on 1 August 2011 by astronomer Robert H. McNaught at the Siding Spring Observatory in New South Wales, Australia.[5][6][7][8] With an observation arc of 415 days, the comet's nominal orbit solution suggests that its 2010 approach distance was 0.00084 astronomical units (126,000 km; 78,000 mi) from Jupiter's center—well within Jupiter's Roche limit at which the comet would be torn apart by tidal forces.[3][4] The earliest precovery image of the comet was taken by Pan-STARRS 1 on 6 December 2010, two days after the comet's close pass with Jupiter.[2]
