Space is cold, yes, but how cold is space? Well, the temperature in space can fluctuate up to -455 degrees Fahrenheit . Space is almost empty even though it has some particles or molecules passing by. In a vacuum, the heat can only travel through radiation. When the objects collide, conduction can take place and heat can get transferred but other than that, radiation is the only way heat travels around. On earth, we lose most of the heat from our body, when the atoms in body collide with atoms of air or water. Scientists usually consider the average temperature of space around 2.725 Kelvin, that’s near absolute zero. In this temperature, molecules move extremely slowly unless they interact with other particles or molecules.
