1. It is often stated that the dates of perihelion and aphelion change over time and make one complete cycle every 22,000 to 26,000 years. This is because of earths precession. My question is if an arrow was drawn pointing from the sun to the earth on the moment of perihelion and that arrow, if continued out, would point at some galaxy "X" would that arrow still (ignoring galatic motion) point to galaxy "X" 10,000 years later at the moment of perihelion?
2. Is there both rotational AND revolutional precession of the earth. If so; what is the duration of the later?
