The exosphere is the uppermost layer of a planet's atmosphere, where molecules are collision-less and gravitationally bound. Learn about the lower and upper boundaries of the exosphere, and how it varies for different celestial bodies such as Earth, Mercury, and the Moon.
28 Ιουν 2019 · The exosphere is the outermost layer of Earth’s atmosphere, about 6,200 miles (10,000 kilometers) thick. It’s where the atmosphere ends and outer space begins. Learn more about the exosphere and its gases, temperature and size.
The exosphere is the uppermost region of Earth's atmosphere with no clear upper boundary. It extends from about 500 to 1000 km above the surface, and some scientists consider it part of space.
21 Ιουλ 2019 · Updated on July 21, 2019. The exosphere is the outermost layer of the Earth's atmosphere, located above the thermosphere. It extends from about 600 km until it thins out to merge with interplanetary space. This makes the exosphere about 10,000 km or 6,200 miles thick or about as wide as the Earth.
20 Ιουν 2023 · Height and thickness of the exosphere. The exosphere does not have a defined height as it gradually recedes into space. However, its thickness is estimated at several hundred kilometers.
20 Αυγ 2024 · Exosphere. This is the outermost layer of the atmosphere. It extends from about 375 miles (600 km) to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth. At the bottom of the exosphere is a transition layer called the thermopause.
2 Οκτ 2019 · Learn about the five major layers of Earth's atmosphere, from the troposphere to the exosphere, and their characteristics and functions. The exosphere is the highest layer, extending from 700 to 10,000 kilometers above Earth's surface, where molecules are so rare that they escape into space.
