Australian astronomer, Malcolm Hartley, discovered Comet Hartley in March 1986. It orbits the Sun once every 6.5 years. It will be the brightest comet predicted for 2010 at an estimated magnitude 5 (this is only a prediction). This will occur in October and it is emerging from Cassiopeia to traverse Perseus and then hit Auriga in October. On October 8/9th it will be in Perseus at the Double Cluster that is 7,000 light years away. As stated in the below article, this will be a good time to view the comet with a backdrop of a cloud of stars.
Get ready for a naked eye comet If the Feast of Trumpets is correctly placed in the fall, then this day of October 9 and the comet coincide. Of course we cannot determine what a comet will do–look at the Comet Holmes explosion of 2007. What is most fascinating is that with an orbit period of 6.5 years, that exact time later from October 9, 2010 will come to April 11, 2017. This day in 2017 happens to be Passover. In the analysis of Comets Hyakutake and Hale-Bopp, the day of April 11th came up as significant. Comet Hyakutake crossed the star of Al-Gol in Perseus on April 11, 1996. Hale-Bopp did the exact same thing in 1997 on this very day. Perseus is the “breaker of the imprisoned”, Al-Gol means “evil spirit” which is located in Medusa’s (Satan’s) head, which means “trodden underfoot”. Think Genesis 3:15. Of course, when considering the timing of Passover in AD 32 , it would have been April 11th (Nisan 15) as well with our Savior’s crucifixion and death at day’s end on April 10th. When this was discovered seven years ago, a search produced the following years that had a Passover on April 11th: 1914 - World War I began this year. The sign of the end of a plurality of nations against nations. 1933 - Hitler’s rise to power and the anti-Semitic laws were enacted on this very day of Passover. 1998 - Israel’s 50th Anniversary. 2017 - Our Lord’s return at the final war. No other years in this range had April 11 Passovers. The other nearest years were 1865 and 2028. So it is interesting that this comet’s orbital period matches October 9, 2010 to April 11, 2017 at 6.5 years. If our Lord does return in 2017, then it is amazing that the solar lineup matches AD 32 when He departed, since Passover coincides with the same day as our solar calendar in both years. And don’t forget, this comet is passing through Perseus as well!
