The mesosphere is the coldest layer. In the outer mesosphere, temperatures approach -90 degrees Celsius.
However, a thermometer would measure the thermosphere to be well below 0 degrees Celsius. The thermosphere is actually very hot. It can get up to 1, 800 degrees Celsius. You would not feel that warmth though because temperature is the average amount of energy in motion of each molecule of a substance. The gas molecules in the thermosphere move very rapidly, so the temperature is very high. The molecules are spread very far apart and there are not enough of them to collide with the thermometer and warm it very much.
If you are researching this, all I can tell you is to not believe what other people are saying about the fact that the higher you get, the colder it is because the evidence is perfectly clear that it is not true.

The Mesosphere has the lowest temperature of the layers of Earth's atmosphere because Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −100 °C (−148.0 °F; 173.1 K)
The mesosphere is where meteorites burn up. Most people call them shooting stars.
The Mesosphere is the third layer in the Mantle.It is approximately 2550 km in depth. It is the biggest part of the Mantle. It extends from the bottom of the Asthenosphere to the core.
The crust is?æneither troposphere, stratosphere, mesosphere?æ nor exosphere; these are layers of the atmosphere. The crust and the upper part of the mantle makes?æup the lithosphere.
The atmosphere is divided into five layers. It is thickest near the surface and thins out with height until it eventually merges with space. The layers from lowest to highest : - The Troposphere (up to 10 km) It's the atmosphere that surrounds us. On top of that comes... - The Stratosphere (10-50 km) Very little oxygen or water vapor. Aircraft fly in the lower stratosphere. This is also where the ozone layer exists. On top of that comes... - The Mesosphere (50-80 km) This is where most meteors burn up, because the density is higher than the outer layers. On top of that comes... - The Thermosphere (80-650 km) Practically a vacuum. Includes the ionosphere (auroras) as well as space station orbits. On top of that comes... - The Exosphere (500-2000 km) The farthest any of Earth's atmosphere exists. Based on charged particles and not necessarily gas molecules, some atmospheric models combine the Exosphere into the Thermosphere, making the outermost layer the Magnetosphere, a vast region where atmospheric ions interact with the solar wind in space.
mesosphere
The coldest layer of the atmosphere is the mesosphere, which extends upwards from about 31 miles to 53 miles above the Earth's surface. Temperatures in the mesosphere can drop as low as -130 degrees Fahrenheit (-90 degrees Celsius).
The coldest layer of the atmosphere is the mesosphere, which starts around 31 miles (50 kilometers) above the Earth's surface and extends up to about 53 miles (85 kilometers). Temperatures in the mesosphere can drop as low as minus 130 degrees Fahrenheit (minus 90 degrees Celsius).
The coldest layer of Earth's atmosphere is the mesosphere. Temperatures in this layer can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit).
The Mesosphere.
The coldest layer of the atmosphere is the mesosphere, which sits above the stratosphere and below the thermosphere. Temperatures in the mesosphere can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit), making it extremely cold.
No, the ionosphere is not the coldest layer of Earth's atmosphere. The coldest layer is actually the mesosphere, which is located above the stratosphere and below the thermosphere. Temperatures in the mesosphere can drop as low as -90 degrees Celsius.
yes
Mesosphere
The coldest layer of the atmosphere is the exosphere (space). If you were to not count the exosphere, the coldest layer would be the mesosphere.
Mesosphere
The second coldest layer of the atmosphere is the mesosphere, which sits above the stratosphere and below the thermosphere. Temperatures in the mesosphere can drop as low as -90 degrees Celsius.
