Question

What is the temperature in outter space?

Answer 1

Interstellar matter varies widely in temperature, from about 8 K to tens of millions of degrees.  It depends on the state of the material, its density, nearness to sources of heat, etc.   Different phases of the interstellar medium have different characteristic temperatures:

dense molecular gas: 8 to 12 K

warm molecular gas: 20 to 60 K

warm atomic gas: 50 to 200 K

ionized hydrogen regions: 4000 to 12000 K

hot ionized medium: 100,000 to 30,000,000 K

Answer 2

There is no temperature in outer space. Temperature is a property of matter. Space is a vacuum, devoid of matter, therefore can have no temperature.

However, objects in space can have temperature, and that temperature will depend on many factors, including incoming heat from the Sun and the properties of the object. A shiny metal object spinning rapidly will reach a different temperature than a dull black object spinning slowly, for example.

Answer 3

-459.8 degrees

Answer 4

Depends on the distance you are from a star and where in space you're talking about

Answer 5

The entire Universe is filled with the remnants of the Big Bang, in the form of photons (electromagnetic packets). They have cooled down to about 2.7 Kelvin or 2.7 degrees above absolute zero (-270.7 degrees Centigrade). So this is the temperature of space. It can be calculated from the expansion of the Universe, and it has been measured.

You can learn more about the COBE mission that measured this on the TopHat web site.

Is it correct that objects in deep space (not heated by an external source, such as the Sun) have a temperature near absolute zero - but the void itself has NO temperature?

Answer 6

It's very, very cold; only a couple of degrees above absolute zero (-273.15°C or about –460°F). But if you're in direct sunlight the temperature soars to hundreds of degrees since there is no atmosphere to attenuate the radiation or to draw away surface heating; radiative cooling is the only method possible.

Answer 7

On a space ship in near orbit it will be plus 300 deg. F. on the sun lite side. On the shade it is minus 250 deg. F.
