Comet Elenin - 10000 times more rare than Haleys comet.... coming this October!!!
C/2010 X1 will come to perihelion (closest approach to the Sun) on 10 September 2011 at a distance of 0.4824 AU. On 16 October 2011, the comet will pass within about 0.233 AU (34,900,000 km; 21,700,000 mi) of the Earth at a relative velocity of 86,000 km/hr. The Minor Planet Center ephemeris shows this relatively bright comet will reach about 6th magnitude near mid-October 2011, but until the activity level of the coma is better known it is still uncertain just how bright this comet will become. Elenin will make its closest apparent pass in the night sky to Comet 45P/Honda-Mrkos-Pajdušáková on the morning of October 8, before moving apparently close to and in front of Mars on October 15. The comet came to opposition at 178° from the Sun on March 14 and will come to opposition again on November 22 at 175° from the Sun. The minimum angle between the Sun and comet will occur September 26 (1.9°), and between July 28 and October 10 the comet will be less than 45 degrees from the Sun
