Quizplus · Accepted Answer

A sidereal day is the time it takes for a planet to rotate once on its axis relative to the fixed stars. A solar day is the time it takes for a planet to rotate once on its axis relative to the sun. Because the Earth is also moving around the sun, it takes slightly longer for the sun to appear in the same place in the sky each day, resulting in a solar day that is about 4 minutes longer than a sidereal day.
