Another way to see this difference is to notice that, relative to the stars, the Sun appears to move around Earth once per year. Therefore, there is one fewer solar day per year than there are sidereal days.
The siderial day is the time it takes the Earth to rotate once on its axis. The solar day is the time it takes for the Earth to rotate once relative to its position in respect of the sun. This is not the same thing, as the earth is orbiting the sun at the same time. loris Â· 2 years ago
