If you were to go outside and look at the sky at intervals of exactly one solar day how would the position of the sun and stars change, during daytime and during night?
In the celestial sphere, day and night skies are opposites. If the constellation Aquarius is in night sky, Leo will be in the day sky. Stars appear to turn at the angular rate 0.9856 deg/day.
Angular orbital speed of the observer about the Sun is 360/385.256 = 0..9856 deg/day. Day or night, we see the same configuration of stars, only after one year
