Comet 67P\/Churyumov-Gerasimenko is the comet made famous by ESA\u2019s spectacular Rosetta mission. This month it can be found passing from Gemini into Cancer. At 00:00 UT on 1 November, 67P is located 2\u00b0 southwest of mag. +3.8 Iota (\u03b9) Geminorum, and predicted to appear at integrated magnitude +10.7. On the night of 3\/4 November it passes approximately one degree south of Iota Geminorum heading east. It lies 40 arcminutes southwest of mag. +4.1 Upsilon (\u03c5) Geminorum at 00:00 UT on 5 November, and southeast of the star by a similar distance at 00:00 UT on the 6th. At 00:00 UT on 8 November it lies 1.6\u00b0 south of Pollux (Beta (\u03b2) Geminorum). The comet then passes close to mag. 5.0 Phi (\u03c6) Geminorum on the nights of 9\/10 and 10\/11 November, and 30 arcminutes south of mag. +5.1 Chi (\u03c7) Cancri on 18\/19 November. 67P can be found 2\u00b0 south of mag. +4.0 Iota (\u03b9) Cancri during the morning of the 30th. The comet remains at a fairly constant brightness throughout the month and is predicted to dim marginally to mag. +10.9 by its end.<\/span><\/p>\n\n

67P\/Churyumov-Gerasimenko is a Jupiter-family comet. This is a class of periodic comets with orbital periods less than 20 years, and orbital inclinations of less than 30\u00b0. Its orbit takes it out as far as 5.63 AU from the Sun at aphelion and in as close as 1.243 AU at perihelion. The next perihelion occurs on 2 November.<\/span><\/p>\n\n

The comet was discovered by Klim Ivanovich Churyumov while examining a photo taken by Svetlana Ivanovna Gerasimenko on 11 September 1969.<\/p>\n\n
