how long around the earth is the equator
The circumference of the earth at the equator is 24,901.55 miles  (40,075.16 kilometers). But, if you measure the earth through the  poles the circumference is a bit shorterâ¦ - 24,859.82 miles (40,008  km). This means the earth is a tad wider than it is tall, giving it  a slight bulge at the equator.
