Why does a solar day last longer than a sidereal day? O Because the tidal effects of the Sun and Moon are gradually slowing the Earth's rate of rotation, making the days longer. Because that's how they defined it. Because the Moon going around the Earth pulls the Earth around a bit faster than if there were no Moon. Because the Sun accelerates the Earth, but the distant stars don't. Because the Earth is orbiting the Sun, it has to rotate about one extra degree each day to bring the Sun back to the same point in the sky as seen looking out from Earth.
