thread_title: 1944

message: there is a paragraph like this in the text:
"The tail of Comet Encke was temporarily torn off on November 1st, 2007 by magnetic field disturbances caused by a Coronal Mass Ejection (CME) - a blast of solar particles from the sun. The tail will grow back due to the continuous shedding of dust and gas by the comet.[1]"
in the description the event is on Nov.1, 2007,
while the reference is linked to a APJ news in October, 2007.  —Preceding unsigned comment added by Isotisp (talk • contribs) 06:31, 6 September 2008 (UTC)

message: How long is the distance comet Encke travels in three years?  How many kilometers does Encke travel in its orbit around the sun?  209.40.210.222 (talk) 04:46, 26 February 2009 (UTC)

thread_title: Length of Orbit

message: The info on the orbit of this comet is in the info box, but it would be helpful if there was a diagram of the inner solar system, showing the orbit of the comet against the background of the orbits of Mercury, Venus, Mars and Earth. Does the comet move in much the same plane as these planets. Myles325a (talk) 03:29, 17 February 2011 (UTC)
thread_title:  How about a diagram? 

message: In this article, it says that "During the November 2013 perihelion passage the comet is expected to brighten to apparent magnitude 7". However, the Starry Night program says that 2P/Encke is already brighter than magnitude 6. I think this should be clarified. Carbon6 talk 04:55, 10 November 2013 (UTC)
replies: text: Seiichi Yoshida says It is only magnitude 7 as of Nov 8. Besides, Starry Night is a generic astronomy program making a crude guess. -- Kheider (talk) 08:54, 10 November 2013 (UTC)
