If we view the Earth's orbit from north of the ecliptic plane, then we will see the following:<BR/>The Earth orbits counter-clockwise.<BR/>The summer solstice precesses clockwise.<BR/>The perihelion precesses counter-clockwise.<BR/><BR/>Currently, the perihelion is on January 3rd, and it will slowly move later in the year. Does this answer your question?<BR/><BR/>This information was gleaned from Wikipedia and my primary source (cited above).millerhttps://www.blogger.com/profile/05990852054891771988noreply@blogger.comtag:blogger.com,1999:blog-9124539381685751273.post-73771083395604100682008-12-30T20:14:00.000-08:002008-12-30T20:14:00.000-08:001) Is the eccentricity increasing or decreasing?2)...1) Is the eccentricity increasing or decreasing?<BR/>2) Is the precession at Summer Solstice heading more towards the earth or further away?<BR/><BR/>Without these facts I can't picture where we are heading?
