DYK? Earth's Rotation The Earth rotates on its axis relative to the sun every 24.0 hours mean solar time, with an inclination of 23.45 degrees from the plane of its orbit around the sun. Mean solar time represents an average of the variations caused by Earth's non-circular orbit. Its rotation relative to "fixed" stars (sidereal time) is 3 minutes 56.55 seconds shorter than the mean solar day, the equivalent of one solar day per year. https://solarsystem.nasa.gov/basics/chapter2-1/ That's how fast the Earth rotates! Pretty amazing huh!!!... We can't even feel its movement, we just notice it because of the sun😊 #DidYouKnow
