How Cold Is Space Near Earth
Within near and distant galaxies the mesh of dust and clouds that weaves between the stars has been observed at temperatures between between 10 and 20 kelvin.
How cold is space near earth. A piece of bare metal in space under constant sunlight can get as hot as two hundred sixty 260. The sparse pockets of space that. The earth could not shed the tremendous amount of heat it receives from the sun.
If atoms come to a complete stop they are at absolute zero. The most empty space which still not empty is the inter galactic space and only in some situations also. The average temperature of outer space near earth is 283 32 kelvins 10 17 degrees celsius or 50 3 degrees fahrenheit.
Temperatures can get up to 2 700 degrees f 1 500 c at this altitude. Eventually its oceans would boil. Let s look close to home in orbit around the planet at the international space station.
This is still very cold but nowhere near as cold as somewhere in deep space far from any sunlight. In empty interstellar space the temperature is just 3 kelvins not much above absolute zero which is the coldest anything can ever get. And now this is actually very related to why mountains are cold.
There the universe has it s background radiation which is 2 725 degrees kelvin. The temperature of things on earth is sort of in balance between the amount of heat which is arriving either from the sun or from heat moving around the world and the amount of heat it can lose by radiating into space. A measure of how wiggly atoms are.
But to give some context you first need to understand heat as scientists do. Hot things move quickly cold things very slowly. Space is just above that at an average temperature of 2 7 kelvin about minus 455 degrees fahrenheit.
