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.[4]
The comet came to perihelion on 1 October 2012,[1] and was expected to reach about apparent magnitude 15.2, but due to an outburst the comet reached apparent magnitude 8.[5] 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.[6] On 19 October 2012, images by the Virtual Telescope Project showed a dust cloud trailing the nucleus.[7] Images by the 2 m (79 in) Faulkes Telescope North on 26 October 2012 confirm a fragmentation event.[8] The secondary fragment was about magnitude 17. Further observations by the 8.1 m (320 in) Gemini telescope show that the comet fragmented into at least 4 parts.[9]
