Our Solar System is travelling through a cloud as hot as the surface of the sun!

The Local Interstellar Cloud, is an interstellar cloud that is approximately 30 light years long. Our Solar System entered this cloud anywhere from 44,000 and 150,000 years ago, and is expected to make it's exit in the next 10,000 to 20,000 years.

This cloud, that we are in at this VERY SECOND, is as hot as the surface of the sun, or rather around 6,000K. That is, of course, 5,600 degrees Celsius or 10,000 degrees Fahrenheit.

So, why exactly haven't we become a fiery ball of hell? Well, the effects on Earth are prevented because of solar winds, and our Sun's magnetic field, which essentially acts as a bubble to keep out heat that would otherwise destroy our solar system.
