What's the temperature of outer space and why?
    #3912345 - 03/13/05 06:36 PM (11 years, 8 months ago)

I'm curious about this.

It will vary, in extreams. Depending on how close to the sun (or other star) you are. Or if there is a large object (a planet, moon, etc.) directly between you and said star. In the shadow of an object or just far away from a star, it will be very, very cold. Nearer a star it becomes quite hot.

cold, real cold. except next to our sun.
cause it's a vacuum.

Hmm, what about in the huge spaces between everything?

Marijuana makes me think there has to be some common temperature in space.

Depends on where. Clearly the vast majority of outer space is vacuum. In a vacuum, there is no such thing as temperature. Temperature is a measure of kinetic molecular energy, but in a vacuum, there are no molecules, and since there aren't any molecules, there cannot be a temperature. However, planetary and celestial bodies aside, there are gases in outer space, and they can range in temperature from 2K to millions of degrees K.

An interesting question would be what temperature is a black hole.

Ok, I think I undestand you question but I dont have an answer. Umm, check the Kelvin scale. There is an exact temp for complete lack of energy using the Kelvin scale. Complete lack energy meaning no motion, no radiation, pretty much a nothingless, motionless state.

Im not a scientist and thats pretty much the extent of my scientific knowledge concerning the subject.

I knew there was an answer.

So, there is no temperature in a vacuum? How does that work?

How can you even travel in a vacuum?

P.S. The temperature of a black hole is fucking hot.

What you're thinking of is absolute zero (0K). However that doesn't apply to most of outer space, because there are no molecules there in the first place.

So... if Nasa built a thermometer and tossed it into the vacuum of space... What exactly would the thermometer indicate?

I've read an article about this very thing some years ago. I can't give you an exact figure, but I recall the average temperature in space is somewhere close to absolute zero (About -460 degrees fahrenheit) for the reasons listed above, that is, that most of the universe is simply space....

A vacuum is a strange thing to comprehend. It is simply nothingness.

Rockets are able to travel in space, because the shells are able to withstand enormous amounts of pressure. Their engines are very powerful, and Newton's third law really goes into this more. Gases are expelled from the engines with enormous momentum; since there is a conservation of momentum, the rocket must move forward.

I wonder where black holes go, if anywhere?

If you put a thermometer in the blackness of space between the stars, where there's very little gas or light, the temperature shown would drop very low. This is because the thermometer would be emiting more energy through radiation than it would be absorbing. If the thermometer was wet, or if there was some way for molecules to escape from the surface of the thermometer, it would drop more quickly, because these molecules would take energy with them.

Nothing, it would probably implode or explode.

Yes, the laws of motion and inertia still apply in a vacuum....

If the thermometer was designed to withstand the rigors of space, it wouldn't necessarily explode.

The internal pressure would exceed the external pressure, but if the container was strong enough, the thermometer would still work.

It would read a very small number, because the thermometer would be emitting IR radiation, but getting very little energy in return.

this guy says+120degrees C to -100 degrees C. http://hypertextbook.com/facts/2002/MimiZheng.shtml
things like our space craft, when we had them, could travel through space because the were pressurized, one pin hole tare, and pressure death.
rocks and chunks of planets can be in a vacuum cause there is no splat-able organics.

Shouldn't there be ridiculous amounts of dust/tiny rocks flying through space?

Why wouldn't they rip right through a spacecraft?

they do.
yet another reason space exploration is really further down the road than one would like.
one little uncharted rock could wreck something.
