Often, our Special Agents answer questions that are so intriguing that they are inclined to do further research. So here is our Agents choice for question of the day:
What temperature is it in space? Empty space itself cannot have a temperature as it is a vacuum (an absence of matter). An object (matter) that absorbs & emits radiation perfectly, at the Earth’s distance from Sun, will reach 7 degrees C.
More details:
If an object is shielded from the Sun but exposed to interplanetary and interstellar radiation, it reaches about 5 Kelvin. If it were far from all stars and galaxies, it would come into equilibrium with the microwave background at about 2.7 Kelvin.
Space is the unlimited expanse in which everything is located. We can say Space or Outer Space is the seemingly empty places (vacuum) between planets and stars. Space is not really empty, but the material in space is so dilute that it is really hard to detect it.
Along with the conservation of matter and energy there is a universal, fundamental truth or principle of the conservation of Space; that Space cannot be created nor destroyed. Matter, energy and Space each have an essential and indispensable role in existence.
Matter and energy are conserved in Space and, in turn, space is in every way conserved as a place where matter and energy exist. Neither being created, destroyed, nor affected in any way by energy, motion and matter, space remains.
