Re: Corona Temperature

As long as we agree that “heat” is the measurement of the movement of atoms and molecules, then we both probably agree that “density” matters.

For instance, if the temperature of the Earth's atmosphere was 1 million degrees, the Earth's surface would vaporize in a couple of minutes.

However, if the density of the Earth's 1 million degree atmosphere was reduced by 99.99%, it would probably take centuries for vaporization to occur, or maybe even never.

“Super-heating” in the corona is a really interesting puzzle, but I think most people imagine the corona in terms of the density of the Earth's atmosphere, which is not correct.

Since it’s orbiting the sun does it have a rear facing camera so it can scan for Nibiru?

Putting a probe on a longer-period object has actually been suggested for outer solar system exploration. Trick is, catching the object with chemical propulsion...
