Does the Moon follow the same path across the sky as the Sun?
MICHAEL MCCOY, OCALA, FLORIDA
As Earth orbits the Sun each year, the Sun appears to cross in front of more than a dozen constellations. As observers on a nearly circular path that takes 365 days to complete, we find the Sun moves approximately 1° per day against the background stars. This movement defines a line, called the ecliptic, around the celestial sphere. The ecliptic is inclined 23.5° to the celestial equator because this is the amount Earth's rotation axis is tilted relative to its orbit.
