168P/Hergenrother
Template:Short description Template:Infobox Comet
168P/Hergenrother is a periodic comet in the Solar System. The comet originally named P/1998 W2 returned in 2005 and got the temporary name P/2005 N2.[1] The comet was last observed in January 2020,[2] and may have continued fragmenting after the 2012 outburst.
2012 outburst
The comet came to perihelion on October 1, 2012,[3] and was expected to reach about apparent magnitude 15.2, but due to an outburst the comet reached apparent magnitude 8.[4] As a result of the outburst of gas and dust, the comet was briefly more than 500 times brighter than it would have been without the outburst.[5] On October 19, 2012, images by the Virtual Telescope Project showed a dust cloud trailing the nucleus.[6] Images by the Template:Convert Faulkes Telescope North on October 26, 2012, confirm a fragmentation event.[7] The secondary fragment was about magnitude 17. Further observations by the Template:Convert Gemini telescope show that the comet fragmented into at least four parts.[8]
2019
168P came to perihelion on August 5, 2019,[2] when it was 76 degrees from the Sun. It then made a closest approach to Earth on 6 November 6, 2019, when it was Template:Convert from Earth with a solar elongation of about 110 degrees. It was not recovered until January 3, 2020, when it was 141 degrees from the Sun, but only two observations on a single night were reported.
