how far is the mesosphere from earth surface
1 Mesosphere The mesosphere extends from the upper boundary of the stratosphere up to 85 kilometers (280,000 feet) above the Earth. 2  Shooting stars (meteors usually burn up in the part of the atmosphere. 3  It is also the coldest place on Earth.
The mesosphere starts at 31 miles (50 km) and extends to 53 miles (85 km) high. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere with temperatures averaging about minus 130 degrees F (minus 90 C). This layer is hard to study.he mesosphere starts at 31 miles (50 km) and extends to 53 miles (85 km) high.
