What part of the atmosphere is considered outer space?
Although the thermosphere is considered part of Earth’s atmosphere, the air density is so low in this layer that most of the thermosphere is what we normally think of as outer space. In fact, the most common definition says that space begins at an altitude of 100 km (62 miles), slightly above the mesopause at the bottom of the thermosphere.
What is the definition of outer space?
Definition of outer space : space immediately outside the earth’s atmosphere broadly : interplanetary or interstellar space : the region beyond the Earth’s atmosphere in which there are stars and planets : the region beyond earth’s atmosphere and especially beyond the solar system
Is outer space a layer of the atmosphere?
Outer space is measured in relation to Earth’s atmosphere, which consists of five layers: stratosphere, thermosphere, troposphere, exosphere, and mesosphere. Based on general boundaries of Earth’s surface, outer space begins 62 miles above Earth’s surface.
