In 2007, there was a huge explosion of comet Holmes/17P I remember looking at this, and before it was over it was reported to be 21 times larger than the Sun in the sky. It was reported the comet started as a tiny little rock of ice. House size, and EXPLODED somehow becoming larger by the minute and it's visible mass looked 21 times larger then the area the Sun appears as in the sky above, and few took note. Yet I reported this event online through websites like timebomb2000 and GLP. When this explosion occurred within a day or two, 17P/Holmes briefly became the largest body in the Solar System. Not only this, its brightness had also increased millions of times. Since then, its dust, gas and ashes have come to the interior of the solar system. And this year it will also be visible from the sky of the Earth.

What is the source of such energy? Does it come from within the comet or without? Alas, comets remain largely mysterious. https://www.space.com/4544-obscure-comet-brightens-suddenly.html http://img87.imageshack.us/img87/7909/195284mainholmes200jj7.jpg https://www.thunderbolts.info/tpod/2008/arch08/080506holmes.htm " the largest object in the Solar System". https://authors.library.caltech.edu/18982/ Thus, it turned into" the largest object in the Solar System". Scientists believed that this dust would dissipate quickly, but recent studies have shown that it flies around the Sun in an elliptical orbit, passing through the ejection point. https://universemagazine.com/en/trace-of-a-giant-comet-flare-can-be-seen-in-july/ In 2007, a mysterious explosion in Comet 17P/Holmes caused it to become 400,000 times brighter, and its coma reached 70% of the Sun’s size.-
