whats the tempeture in space??
The temperature in space varies from the very cold -- from almost absolute
[-273.15C] to millions of degrees in stars. The temperature of an object
suspended in space -- a space shuttle or a planet -- will be hot or cold
depending upon the amount of radiation that it absorbs. In our solar system
that means the Sun. So in shadows it gets very cold, and in the sunlight it
gets very hot. Of course, how far away the object is from the Sun is
important since the intensity of radiation falls off as 1/D^2 where D is the
distance from the Sun.
In a pure vacuum temperature does not exist. Temperature is a measure
of the energy of the motion of the molecules in a substance. No
substance.... no temperature.
In reality, space is not a perfect vacuum, but it is so far between
molecules, that it is difficult to talk about temperature in a
