The temperature in space is close to "absolute zero" because any object there will radiate heat until it cools to that point. This is for objects not exposed to direct sunlight. In Earth orbit, the temperature of objects in sunlight can rise to 120Â°C/ 250Â°F. The actual temperature in space is about 3Â°K (-270Â°C or three degrees Celsius above Absolute Zero). There are still molecules in space, just very few of them, and this is their temperature.
Absolute zero is a theoretical temperature where the thermal kinetic energy of the molecules in a body goes to zero. This cannot be achieved through artificial or natural means, because there is no way to remove the last small amount of thermal energy. The coldest temperature in space is about 3Â°K above absolute zero. This is defined as the Cosmic Background (or Microwave Background) Radiation that was first detected by Penzias and Wilson using the Holmdel Horn Antenna in New Jersey, USA in 1965. This radiation quite literally is the echo of the Big Bang.
Assuming you're measuring the temperature of pure space, or an area in which there is no matter that could absorb the sun's radiation and thereby heat up, the temperature would be -459Â° Fahrenheit, -273Â° Celsius, or 0 on the Kelvin scale.Cosmic Background RadiationThe temperature is not absolute zero because there is a pervasive background radiation, with an equivalent temperature of 2.7 K. Alternate view:This is an amateur opinion. When measuring, for example, the heat of a distant star, one is not measuring the heat of the intervening space, even though the radiation we are detecting passes through it. It is possible that the same thing can be argued for the background radiation. An analogy might be that if a photon of light reaches earth, it is because that photon was not absorbed by anything during its trip, not even the tiniest particle of matter. Clearly, photons that are absorbed along the way never reach us. It might even be possible in a weird quantum sense that the photon may just be a probability greater than 0 and less than 1 until and unless it is absorbed by something.
So it may be that completely empty space has no temperature at all (not even absolute zero), because there is nothing in it to either absorb or be void of heat. Empty space is not capable of absorbing or radiating heat. If a thermometer were placed in absolutely empty intergalactic space, it would probably eventually register the background radiation, but this would be because the thermometer itself has absorbed radiation that would otherwise not have been absorbed and that would have continued to propagate through space.
Here is another way to consider the same question. Say that a perfect or near perfect vacuum could be created here on earth, in a lab at ordinary room temperature. What would you claim to be the temperature of this vacuum, and what information would you use to support your claim? Temperature is a characteristic of matter, and not of vacuum.Correction to the aboveThe question does not ask the temperature OF space, but rather IN space. Radiation from anything in space will cool it without any need for a conducting medium. The loss of heat will continue until the object reaches very nearly absolute zero. If an object receives sufficient radiation from the Sun, it will heat only the surface exposed to the Sun, and cool from the others. So spacecraft that are designed to reflect the Sun's heat will need another heat source to keep the interior warm. This varies from temp to temp. Usually it is 2-4 degrees kelvin. Sometimes hotter depending on where you are in space. Otherwise it is -400 degrees Fahrenheit. Pretty darn cold if you ask me. Don't go into the cold recesses of space without a space suite.
Basically, a space suit regulates temperature against the freezing temperature of space, provides pressure that keeps you from exploding, and provides oxygen so you don't suffocate.
The vacuum in space only has one temperature: -273.15 degrees Celsius. The planets' temperature do vary, though.
because you get closer to space and in space there is no atmosphere
If you're talking about actual space, as in vacuum, the only temperature is about -273.5 degrees Celsius, as no atoms move in space. On planets and stars, temperature can vary dramatically, from the temperature of vacuum to the core of the hottest star (could be 40 million Celsius).
It is -121 to -156
the moon has that temperature because of the gravitational pull in space
The temperature of outer space is measured in Kelvin. Water boils at 373 K and frezzes at 273 K.
You can't, temperature is the average kenetic energy of the molecules and in space, there simply are too few or none to measure.
The liquid expands as its temperature increases. This is the same as saying that it occupies more space as temperature increases. Therefore it 'uses up' more of the space inside the thermometer as the temperature increases.
The temperature of outer space is measured in Degrees Kelvin. The Kelvin scale starts at what is called Absolute Zero, and is based on the theory of a "Perfect Vaccuum" (a vaccuum in which no matter exists whatsoever). Space, however, is not a perfect vaccuum. There are various gasses and other particles floating around in it, and for that reason its temperature cannot possibly be Absolute Zero. It would depend on exactly how much matter is present in any given region of space as to that regions temperature in Degrees Kelvin. It is scientifically acceptable to determine the temperature of space to be "fractionally above Absolute Zero", as its (space, as a whole) temperature varies from region to region. How the temperature in space is physically measured is another question, and one I cannot answer.
No, space is a vacuum. Rain requires an atmosphere with temperature differentials.
I looked at so many places but no place tells the temperature
The closer you get to space - the lower the temperature gets.
Space isn't occupied by matter, so it has no temperature by itself. If a comet or asteroid is orbiting the sun, it's actually made of matter and has a measurable temperature as it proceeds in its orbit. (The sun can shine on its surface and sunlight can warm the surface.) Because space has has no way to transfer heat away from objects occupying it by conduction or convection, since it has no matter to do so with, it's an excellent insulator. Space, by itself, has no temperature. Objects in it do have a temperature.
If by space you mean the vacuum of outer space then, as the are very few atoms, there is no temperature as such.This is because what we call temperature (heat) is caused by the vibration of atoms. However, there may be allot of energy passing through a portion of space (electromagnetic energy) but, if this has no matter to impinge on, it does not deposit this energy. There are however some portions of space (in nebulae) where, although there is not much matter, what matter there is, is hot an may even be radiating energy (emission nebulae). Thus the answer to you question is:- No there is not a constant temperature throughout space.
Air temperature decreases as it rises. This is because there is a vast difference in temperature between space and the Earth. Therefore, the closer you get to space (in this case, the higher air rises) the colder it will be. Air temperature increases as air temperature rises. The temperature of air will tend to decrease the further up it is.
yes,it is from all the peaces in space that makes the temperature increase.
There is no air in space
Close to absolute zero.
In a vacuum temperature is inapplicable. Temperature is a measure of the kinetic energy of the molecules that fill a defined space. In a vacuum there are no molecules so --- no temperature.
In 2003 the Space Ship Challenger recorded a temperature in outerspace of 32 degrees, the temperature water freezes. Little did they know, but upon return the Challengers on-board ice chest was unlatched so skeptics believe the temperature recording was skewed due to the Challengers ice stash floating around in space.
Space itself has no temperature at all. Only matter can have a temperature; the vacuum of space has no matter, therefore no temperature. The matter that's IN space, on the other hand.... When exposed in the sunlight, the sunlight can heat things up quite a lot. In shadow, or far from the Sun, heat energy will radiate away into space and the object can get pretty darned cold. Comments: This is quite a complicated situation. Even "empty space" is permeated by the "Cosmic Background Radiation". So, it's usually said that the lowest temperature in space is about 2.7 degrees above "Absolute Zero". Also, there's a lot of gas and dust spread throughout interstellar space. There is a large temperature range from just a few degrees kelvin up to thousands of degrees and more. Generally speaking though, I agree that the stuff in space, away from nearby stars, is usually very cold. See below for a "related link".
