How fast does earth rotate on its axis
The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers). So Sarah was right, just about 1,000 miles per hour (at the equator) or to be slightly more precise - 1,040.5 m.p.h.
The Earth rotates on its axis at a speed of 1000 miles per hour. It rotates once each day taking 24 hours to complete a full rotation. This is determined by its circumference at the equator.
360 degrees/24 hours = 15 degrees per hour is the rotational speed.
we spin at 1000mph and cruise around the sun at a speed of 67000mph
