The earth's equatorial diameter is listed as 7,926 miles. The circumference of a circle is
(pi) times (diameter),
so for the earth around the equator, it's (7,926 pi) = 24,900.3 miles (40,073.1 km).

The equator is the same age as the current shape of the earth.
Many countries do not cross the equator.
Mercury
it is a mushed 3d sphere
4601.8 miles from the Equator to the Arctic Circle 69.2 miles between latitude lines. From the Equator (0°) to the Arctic Circle (66 .5°) 66.5 X 69.2 = 4601.8 miles
