Where on Earth can you observe all the stars in the sky over an entire year? The Suns position relative to the stars is revealed during the darkness of a total solar eclipse. The actual speed with which Earth orbits the Sun varies slightly during the year, so the speed with which the Sun seems to move along the ecliptic also varies.
