Explanation:
Detailed explanation-1: -The energy left over from the Big Bang warms the whole universe, keeping it well above absolute zero. The average temperature of space is 2.74 Kelvin, or minus 454.7 degrees F.
Detailed explanation-2: -But what of the average temperature of space away from the Earth? Believe it or not, astronomers actually know this value quite well: an extreme-270.42 degrees (2.73 degrees above absolute zero).
Detailed explanation-3: -Space is very, very cold-but not absolute zero. As there is no ‘atmosphere’, space is almost a vacuum-with very few molecules to bounce around energetically. As such, there can be no heat. The temperature in deep space is roughly 2.7 Kelvin.
