Why does the sun rise and set?

It’s not the sun that soars across the sky. The Earth itself is rotating on its axis – one full rotation per day – and that spin makes heavenly bodies appear to rise in the east and set in the west to us Earthlings on the ground.  If viewed from above the celestial north, the Earth would appear to be rotating counter-clockwise. Because of this, to those standing on the Earth’s surface, the Sun appears to be moving around us in a westerly direction at a rate of 15° an hour (or 15? a minute). This is true of all celestial objects observed in the sky, with an “apparent motion” that takes them from east to west.
