Fun convection example: stick your hand in a pot of water at 90 degrees and you'll sustain a major injury. Sit in a sauna at 90 degrees and you'll be quite comfortable for a while. Now hang out in the Thermosphere with almost no gas density and you'll be quite cold despite the name.
Although the exosphere is technically part of Earth's atmosphere, in many ways it is part of outer space. Many satellites, including the International Space Station (ISS), orbit within the exosphere or below.
wrong about the temp just making excuses and not researching what i am saying just regurgitating what you were told not actually looking up what it means.
That is exactly what I am saying. Even though it is very thin the molecules heat and cool and considering the speed they are going we all know you get to moving and it gets hot fast.
ISS orbits at approximately 220 miles (350 km) above the Earth and it travels at an average speed of 17,227 miles (27,724 km) per hour. ISS makes multiple orbits around the Earth every day. 24k feet per second. So it is going to get hot very fast at those temps which is 3600 fh. I mean just think about it .
Yes, it would get extremely hot with a larger density of gas. However, convection is minimal in the Thermosphere and the heat that *is* generated is radiated back out into space.
A Van Allen radiation belt is a zone of energetic charged particles, most of which originate from the solar wind, that are captured by and held around a planet by that planet's magnetic field. Earth has two such belts and sometimes others may be temporarily created.
The astronauts on the ISS do not regularly spend time inside the belts, but from time to time solar storms expand the belts to the orbit of the space station.
