why is it cold in space when you are closer to the sun

Only things *in* space do. So, the closer you are to the sun, the higher the density of photons you’ll be receiving - meaning, the more heat you’ll feel. As the Sun is around 150 million kilometres away, even being on top of Everest only brings you 9km closer – far too small a difference to make you feel any warmer. Category: Earth Science Published: July 26, 2013 . We live in a universe of extremes. The show, modestly titled Some of the greatest scorn concerned his flippant response to the question: “If the Sun is hot, why is space cold?” Nye’s full answer:Become a member to keep reading this story and the rest of our expert analyses on the changing global economy. That’s another matter, which remains to be seen. From the sun out to about the orbit of Mars, spacecraft have little trouble staying warm. The bigger question, of course, is whether anyone will consider MAQRO – a cheap experiment as space science goes – worth a shot. Also, the long daylight hours allow the Earth plenty of time to reach warm temperatures.During the winter, the sun’s rays hit the Earth at a shallow angle. They mostly are wrapped in reflective materials for protection from the sun, and given radiators or other systems to help get rid of the heat generated by their systems.

If the sun is so hot, why is space so cold? How much closer to the Sun could Earth’s orbit get and still be habitable? Since the temperature of the Earth is so much hotter than space, you’d expect that the closer you get to space the colder it gets. You are not always closer to the sun just because you're in space... actually most of space is much farther from our sun than the earth. But if you were out in space it would get warmer as you got closer to the sun.

Space *has* no temperature. You also need to know the answer if you want to carry out low-temperature physics experiments in space precisely because you think it is that cold. The experimental apparatus itself wouldn’t be too exotic. Not colder as in lower temperature, but colder meaning it would have a …

The reason outer space is so cold is because cold is what you get when there is no source of heat nearby.At our distance from the sun, if you put, say, a Mac Truck in space, the side facing the sun will quickly get hot enough to burn you. It keeps us warm, and if you move away from the heater you feel cold. For 2.7 Kelvin, or 2.7 degrees above absolute zero, is the temperature produced by the uniform background radiation or “afterglow” from the Big Bang.But hang on. Latest. Evidently you don’t hit temperatures that low the moment you step outside the Earth’s atmosphere. In order for the space to be hotter, there must be thermal energy. But some theories, as yet still speculative and untested, insist that something else will prevent this weird behaviour in large, massive objects, perhaps because of effects that would disclose something about a still elusive quantum theory of gravity.So the stakes for MAQRO could be big. The surface of the sun stays at an incredibly hot temperature of about 5800 Kelvin all year long. The light does not spread out as much, thus increasing the amount of energy hitting any given spot. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!During the summer, the sun’s rays hit the Earth at a steep angle. For objects large enough to see, containing countless trillions of atoms, decoherence happens in an instant, washing out quantum effects in favour of classical behaviour.In this picture, it should be possible to preserve “quantum-ness” in any system, no matter how big, if you could isolate it perfectly from its environment. The sun is a giant ball of fire driven by nuclear reactions. “The column of air pushing down on your head is shorter. They imagine sticking a “bench” with all the experimental components on the back of a disk-shaped spacecraft, with the disk, and several further layers of thermal insulation, shielding it from the Sun. In order for there to be thermal energy, there must be matter to carry it. But one of the favourite explanations invokes an idea called decoherence, which means that in effect the quantum behaviour of a system gets jumbled and ultimately erased because of the disruptive effects of the environment. In other words, MAQRO should be cold enough to spot if these models are wrong.Could the experiment discriminate between any theories that aren’t ruled out? This idea was used during the Apollo program, where the large, cylindrical Service Module was frequently set into a gentle rotation to keep the temperatures even.Objects also conduct heat internally so the shadowed side of an object sitting in the sunlight near Earth might cool down to only -250 degrees All this is very important to spacecraft designers. But simply knowing that size matters in quantum mechanics would be a major finding. And performing the experiment in zero gravity on a spacecraft could show whether gravity does indeed play a role in the quantum-to-classical transition. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter.

So if you are a long way from the sun, you will radiate more heat that you receive, and you will cool down. During the summer, the sun… Objects in space cannot cool off by thermal conduction or convection, but they Meanwhile, the shaded side of our truck is emitting infrared light too—just at a slower rate. So What makes Earth so different from seemingly the rest of the universe?

That question is sure to prompt the geeks among us to pipe up with “2.7K”.

The problem is that the Sun doesn't work that way. The reason why that's very cold is because if you have pockets of air which is being warmed up on the surface of the Earth and then it lifts up by convection, it's moved upwards, the pressure drops to about half the pressure it was before, which means that gas expands.

But some planned studies also demand zero gravity. Our Mac Truck will probably be tumbling so neither side will have enough time to fully heat up or cool down. Much of the warming would come through the struts holding the bench and shields to the main disk.That’s not really cold enough for the MAQRO experiment to work well.
