June 18, 3502 BC – A rare opportunity for a family photo of all the planets, gathered together in the same region of the sky, in the constellation Leo; as reconstructed by the Stellarium program.
If you haven’t been to this site before, let me recommend the astronomical calendar as an intriguing place to begin exploring. It’s on the menu, under “Writeups”, and lists in chronological order all the new moons, full moons, and lunar eclipses, and many of the conjunctions that have occurred between the planets and the star Regulus since an arbitrary starting point in the distant past (5001 BC). Regulus is the brightest star of the constellation Leo, seen in the middle of the lineup of planets in the above reconstruction. Browse through the calendar searching for a particular type of conjunction, and you can begin to get a feel for the patterns marked out by the planets. For additional info to help you understand what you’re seeing, check out some of the other menu items – Astronomical Background, Normal Stars, Planet Cycles, & Lunar Calendar. Check out the “About” menu for more info on the purpose of this site. Please get in touch if you’d like to collaborate on this ongoing study.
