Rotates on its axis
The Earth is a sphere that rotates, on its axis, passing through the North and South Poles. The rotation is in a counterclockwise direction, looking down at the North Pole.
The Earth is a sphere that rotates, on its axis, passing through the North and South Poles. The rotation is in a counterclockwise direction, looking down at the North Pole.
The time it takes for the Earth to make a complete rotation is approximately 24 hours (exactly 23.934 hours). This rotation results in daytime when an area is facing the Sun and nighttime when an area is facing away from the Sun.
Since we are on Earth, we do not sense its rotation, but we experience it by observing the relative motion of the Sun. It is similar to what you experience when you are sitting in a moving automobile and see the surroundings move by.
Revolves around the Sun
The Earth revolves around the Sun, in a counterclockwise direction, once every 365.25 days. Its velocity in space in its orbit is about 18.5 miles per second.
The shape of the orbit is a slight ellipse. Seldom—if ever—is an astronomical orbit a true circle.
