Well space doesn't really have a temperature, because there is nothing to have a temperature 2.7K Temperature is the vibration of atoms, in space there are really no atoms so space doesn’t really have a temperature. If you put a thermometer in space away from sauces of radiation such as the sun it would slowly cool to 2.7K -454.54Deg F that’s the heat or energy left over from the big bang. The simple answer seems to be " depends on distance from the sun ", Well if you placed a body in space it would start to radiate of its heat the only energy it would receive would be from the Sun so if it was placed close to the Sun it would be warmer than if it was placed at the outer fringe of the solar system.

Jupiter and Saturn kick out some radiation but strictly small beer compared to the sun So, the temperature of space outside Pluto’s atmosphere should be much colder than Earth’s? Yes the temperature of Pluto is measured at 44K (-380 deg F), while Mercury has a mean temperature of 300K ( 86 deg F) (inverse square law). The amount of energy is distributed over a much larger area so the heating effect is much less.

Does the lack of oxygen play a role? None what so ever as oxygen. An atmosphere will act like a blanket reflecting back the suns rays and trapping heat in, an atmosphere of green house gasses will absorb the suns rayys and trap the heat in so Venus has a temperature of 734K 861Deg F What is the temp.

On the moon and what determines it? 220K (-63.4 Deg F) the moon has no real atmosphere so the sun heats up the surface when the suns rays fall on the moon it warms up and when they don't the energy is radiated back into space giving a range of 390K -100K (242 deg F--279 Deg F) so the moon can be very hot or very cold.

Just use a thermometer. Wolfman, Let’s look at this in two different ways-- First, look at the problems we have measuring temperature right here on earth. Okay, suppose the weatherman says the temperature is 65 degrees outside.

So, we take a thermometer and set it in the yard. Oops, we put it in the sun, and it’s reading 80 degrees. Which is the right number?

The weatherman measured the temperature of the air, separated from any nearby objects that might be different, and also NOT in the sun. It seems to me that both answers are right. You have to state rather precisely what you are measuring.

Now, how about out in space? The problem is exactly the same.In my view, the temperature is exactly what you measure, subject to the conditions of the measurement. If somebody asked me for the temperature in space in the viscinity of the earth, I would take a measurement by putting a themometer all by itself (say a hundred yards away from the space station) when on the night side of the earth, in other words in the earth’s shadow--without being in the sunshine.

This temperature would be somewhat warmer than if the earth weren’t nearby of course. And, entirely different than the measurement I would get inside of a satellite or on the dark side of Pluto, which is colder. My understanding is that the coldest places in space are those far away from any celestial bodies--"deep space," right?

That minimum temperature is the "background temperature" of space, something around 4 degrees Kelvin (absolute temperature). This temperature can actually be read from anywhere. It is observable as a continuous microwave spectrum with a frequency distribution characteristic of a "black body.

" The formula for this is Plank’s radiation law. The reason that this radiation can be interpreted as the "background temperature of space" is that we know that all bodies do radiate electromagnetic energy. (On earth, it is infrared "heat.

") And this particular radiation appears to come from no particular place, but seems to come from everywhere. I hope this explanation helps more than confuses. You asked what determines the temperature in space.

The simple answer is that a body in space acquires an equilibrium temperature by emiitting and absorbing radiation from its surroundings. For an object all alone in "deep space," it will be at about 4 deg. K.

Space has very little gases such as oxygen, so heat transfer (and temperature) are determined mostly by radiation. For example, the temperature on the moon is determined just as it is for dirt in your back yard, except that no gases are involved--pretty warm on the sunny side and getting cold (as heat radiates away) on the dark side. Ernie Rogers .

Simple answer The temperature of deep space is about 3 degrees kelvin. This is apparently so, due to residual radiation left over from the "Big Bang" which, as we have been told was neither "big" nor with a "bang"! .

It's complicated here on Earth we have an atmosphere that has a certain temperature and a surface that absorbs the sun's rays. But in a vacuum there's nothing to measure the temperature *of*. Oh you can measure the background microwave radiation, but you get an answer of about -450 degrees farenheit.

If you put an object out in space it will heat up to a certain temp depending on how much sunlight is hitting it. In the shady side of the object it will tend to get very cold, as the heat of the object will tend to radiate out into deeep space, at -450F. On the sunny side it will warm up.

If the object is small or made of something very conductive to heat, the temperature on the hot and cold sides will tend to averge out. If it's made of very insulating stuff, like moon rocks, the temperature difference will be greater. On the Moon the dark parts are down at -200F or so, the parts in the sunlight are at +200 or thereabouts.

Out by Pluto the sunlight is much weaker, so the sunny side of objects does not get very warm at all, maybe -150F? .

2 It's far more than distance from the Sun, Wolfman. There's a lot of Universe out there, more than most of us can imagine. And of course the temperature beyond Pluto, the former planet, is very cold.

Absolute zero is that theoretical state were movement of everything is stopped (or as close as you can get) to the point that energy can not be transferred (heat). That is, about -451 degrees F. The average temperature of the universe is taken to be about 2.73 degrees above that, if I understand the Wiki article.

Still quite chilly. You're right, an atmosphere (and the oceans) plays a part, but the important thing is that we are just the right distance from the Sun to capture just the right amount of energy to support our sorry lives. Quite a miracle actually.

The same energy hits the Moon but there is no atmosphere or water to moderate temp. So on the sunny side it's about 260 F and on the dark side about -280 F.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
