Planets occulting other Planets
I am doing a project to see how many times a planet passes in front of
another one and believe there to be 122 occurances like this in the 6000 years between 3000bc and 3000 ad and was wondering if any have been observed. It would probably not been seen before the telescope was used ands most occur in daylight however it looks like the Mercury in front of Saturn 9th December 1808 at 20h approx and Venus in front of Jupiter 3rd Jan 1818 at about 22h may have been seen. does anybody know if these were seen and if my dates are correct The next 3 seem to be Mercury Saturn on 15 September 2037 at about 22h , Venus Jupiter on 22 November 2065 in daylight at about 13h and Mercury Mars 11 August 2079 at about 02h Paul |

I Googled for planetary occultations and the second entry was http://www.go.ednet.ns.ca/~larry/planets/occltlst.htm. It would probably not been seen before the telescope was used ands most occur in daylight however it looks like the Mercury in front of Saturn 9th December 1808 at 20h approx and Venus in front of Jupiter 3rd Jan 1818 at about 22h may have been seen. Both given there. does anybody know if these were seen and if my dates are correct The next 3 seem to be Mercury Saturn on 15 September 2037 at about 22h , Venus Jupiter on 22 November 2065 in daylight at about 13h and Mercury Mars 11 August 2079 at about 02h No, yes, yes.

I don't know how accurate Stellarium is but it showed as a grazing occultation but at only 1 degree elevation |

I don't know how accurate Stellarium is but it showed as a grazing occultation but at only 1 degree elevation Hi Thanks for your replies I have run it through Cybersky4 and it does show the occultation starting at 21:44:11 and ending 21:53-20 both planets set at 22-04 so it would have looked hard to see. I have been trying to find close ones with Jupiter and Saturn, the best I have found was in the year -1792 1st May JD 1066651.1667 and 28th December -0423 jd 1566919.1250 it looks like there will be a close conjunction between these 2 0n 21st December 2020 ( it looks to be the closest since 1623 July 16th Paul |

I don't know how accurate Stellarium is but it showed as a grazing occultation but at only 1 degree elevation It was incredibly low down (1.4º) and he had cloud interference which meant he missed the actual moment of Mercury entering and leaving the occultation. Details are on this site and his notes are at the bottom of the page. http://www.go.ednet.ns.ca/~larry/planets/1737occl.htm |
