Hi folks, I'm programming some astronomy software and I need information about moments when planets transit through their Perihelia. I only could find the Perihelion longitudes in certain epochs... do you know, where I could find WHEN planets transit through their Perihelia? Thanks a lot.
From this site: http://www.astronomycafe.net/qadir/q47.html Mercury 10/16/1995 Venus 8/11/1995 Earth 12/21/1995 Mars 2/19/1996 Jupiter 5/5/1999 Saturn 5/26/2003 Uranus 3/1/2050 Neptune 3/2030 Pluto 8/1989 This list was generated a few years ago, but gives you a starting point.
