Attached picture shows the solar ecliptic from December to March with planets at 23 January 2008. Can anyone help me add dates over the last few thousand years next to the stars along this line marking when the sun reached the Tropic of Capricorn, ie the sun’s position at the December solstice?
Due to precession, the solar point of the Tropic of Capricorn is now in Sagittarius. It moved through Capricorn from about 2000 BCE to 0 earth years. The spot where Venus is in Sagittarius on the picture marks the current location. It has taken about 6000 years to move along the line from where Uranus is in the picture in Aquarius.
