In the year 1543, a great comet came closer to the Sun than any previous comet had, and this was repeated by another comet in 1882. They actually entered the Sun's corona which supposedly has a temperature of one million degrees absolute. These comets traveled over 1 million kilometers through this blazing corona and emerged unscathed and with no change in velocity or direction. If the Sun is radiating heat, why weren't these comets instantly disintegrated upon entering a tremendous heat of one million absolute degrees? Surely nothing could survive such treatment!
Astronomers have told us that planet Mercury is devoid of life because it is only 36 million miles from the Sun. They also say that if Mercury were any closer, it would have turned into "nothingness" long ago. How then did the two comets survive without at least showing some effects of their journey through the Sun's corona? We must conclude that the answer is that the Sun does not radiate heat, as such. Therefore, it cannot be any kind of a super-hot body.
