Question

The Apparent Motion of the Surn The sun rises in the east, moves across the south, and sets in the west much as stars in non-circumpolar constellations do. Just as for the stars, this apparent motion is really due to the rotation of the earth on its axis The Earth's motion around the Sun adds a complication to the Sun's apparent motion. In a full year, or 365 days, the Earth would go completely around the Sun so that the line-of- sight joining the Sun to the Earth would turn through 360 degrees. In one day, that line turns through approximately one degree. tions the Sun Solar and Sidereal Days The picture below shows the Earth rotating through a full 360 degrees relative to the distant stars. A vertical stick marks a spot that sees the Sun directly overhead when the rotation begins. tive to the Stars t of the Earth's Axis
