How Cold Is Space Without The Sun
For all practical purposes space has no temperature.
How cold is space without the sun. Meanwhile the shaded side of our truck is emitting. As you travel away from the sun the temperature of an object in space plummets. Space is just above that at an average temperature of 2 7 kelvin about minus 455 degrees fahrenheit.
Let s talk a little further out. The surface temperature of pluto can get as low as 240 celsius just 33 degrees. Some stars have a mass 60 times greater than our sun and a surface temperature of nearly 45 000 degrees fahrenheit.
At our distance from the sun that temperature is about 250 degrees fahrenheit. It can t move at all. It s the very diffuse gases and grains that drift through the cosmos whose temperature we can measure.
Temperature is related to how fast the atoms in a substance are moving. At the distance of mercury it s about 800 degrees fahrenheit. Without the sun or a star why is space so cold instead of neutral.
