The Earth's atmosphere doesn't have a definitive boundary, but it is generally considered to extend about 10,000 kilometers (6,200 miles) above the surface. The circumference of the Earth at the equator is approximately 40,075 kilometers (24,901 miles). Therefore, if we consider the atmosphere as extending uniformly above the Earth's surface, its circumference would remain roughly the same as that of the Earth itself, about 40,075 kilometers.
