Temperature Measurement
Many methods have been developed for measuring temperature. Most of these rely on measuring some physical property of a working material that varies with temperature.
The temperature of a black hole is determined by the 'black body radiation temperature' of the radiation which comes from it. (e.g., If something is hot enough to give off bright blue light, it is hotter than something that is merely a dim red hot.) ...
Kelvin temperature scale is the base unit of thermodynamic temperature measurement in the International System (SI) of measurement. It is defined as 1/ 273.16 of the triple point (equilibrium among the solid, liquid, and gaseous phases) of pure water.

Temperature is a physical property of a system that underlies the common notions of hot and cold; something that is hotter generally has the greater temperature.
Color temperature
"Visible light" is commonly described by its color temperature. A traditional incandescent light source's color temperature is determined by comparing its hue with a theoretical, heated black-body radiator.

What is the Temperature of Space?
You've probably heard that SPACE is very hot or very cold. So which is it? Well, for spaceship designers, it's really neither.but that doesn't mean you're off the hook. Confused?
The surface temperatures of the planets vary from more than 400 degrees on Mercury and Venus to below -200 degrees on the distant planets.

This map shows the temperatures for most of the surface of Ganymede made from data taken by the Photopolarimeter/Radiometer (PPR) instrument on June 26, 1996 as Galileo approached the sunlit side of the moon.
Temperature is a measure of the average heat or thermal energy of the molecules in a substance. The atoms and molecules in a substance do not always travel at the same speed.

A measure of the amount of heat energy in a substance, such as air, a star, or the human body.
TEMPERATURE ON EARTH
The temperature on Earth ranges from between -127°F to 136°F (-88°C to 58°C; 185 K to 311 K). The coldest recorded temperature was on the continent of Antarctica (Vostok in July, 1983).
