The reason the stars appear to rise in the east and set in the west is that the stars are in a fixed position and the Earth is rotating, the only way for something in a fixed position to appear to move in the opposite direction would be for us to rotate in the opposite direction, and that will not happen, at least not within a time we will experience. 4) (a) Year: 365 Days; The period of time it takes the Earth to travel along the ecliptic plane around the Sun.
