If the sun is hot, and space is cold, Is there a worm area were space is worm or just when an object hits its rays.

Well, that's a good question!
Space itself contains virtually nothing, so the space itself will not heat up.
Spacecraft rotate to equalise the heat around the craft, so an object in space will heat up!

Good question. Not sure. Let me think.

So, heat, as you and I know it, is energy of motion (kinetic energy) of molecules all around us. When it's hot, air molecules (various molecules in air) bounce around faster, they bump into our skin harder and more frequently and when they do that, they transfer some of their kinetic energy to our skin molecules, which absorb it and vibrate with more energy. If the energy of our bodies' molecules is reduced too far, we'll freeze solid around 0 degrees celcius, since that's where water freezes and we're mostly made of water.

Of course, we also generate energy internally, by digesting food and breaking chemical bonds.

But space is nearly a vaccuum. There is almost nothing to bounce against you.

On earth, the air molecules absorb light energy during the day and move faster. At night, they gradually lose energy, but they lose it slow enough so that we can all survive the night.

The Moon, on the other hand, has no air. According the 1st website I cite below, the Moon varies between -147 to +100 Celcius, depending on whether you are facing the sun or on the dark side of the moon. If the moon, which has no air, has a temperature, then it must be the temperature of the surface, and it obviously gets very hot.

So I would assume that if you were floating around space near the earth, like the moon is, you would also heat up pretty well. The space around you would still be "cold" though, because there is nothing to heat up.

I guess the real answer is, space CAN'T be hot because there is nothing to heat up. But YOU will get heated up depending on how close you are to the light source.

I think this answers your question.

Space is cold yes, the sun is hot yes, but what you have to remember is that space is a vacuum, so cold and hot work a little different, if you where just floating around space say close to are moon so long as you could see the sun there would be a difference in temp. but as soon as you went behind the moon it would get cold again, this is do to the suns rays, that is what you feel also known as solar radiations, the earth is in a perfect location if we where to trad spaces with mars it would get very cold here on earth to the point that life could not be stained, but on the other hand if we trades space with venues we would light up like a Romain candle very very hot. So it boils down to this it is proximity and atmosphere that make all the difference. I hope this helps.

Hey!
I think it's just the atmosphere it's hot...and I have no idea how the heat transfers from the sun to a planet without making the space between them warm? By the way, you wrote worm...sounds kind of funny.

Temperature is not defined for a vacuum. However for planets and other objects the "warm" area around the Sun happens to be approximately at the orbit of the Earth. Any closer and it gets too hot. Any further and it gets too cold.

Hi. Actually it's when the Sun's light hits the object. If you were very close to the Sun, but behind an object, it would be cold.

You would only be affected by radiant heat in outer space. The sun would have to 'see' you, and then it's effects are measured by temperature to the 4th power. You would only have to get outside our atmosphere to be burnt to a crisp by the sun.

Outer space is cold period.
