Task #2 is Why is there a tail behind the green comet?
In MMK's post about the green comet, he left 2 tasks, and the first one was already answered by Wilba... Now here I answer #2
Original post⬇️
Task #2 “Comets are large chunks of rock with a lot of ice and usually don't have a tail. They are frozen rocks in the confines of the solar system and those that approach the interior of the solar system and begin to receive all the energy emitted by the sun begin to volatilize, they go from solid to gaseous. All that dirt that it gives off is what forms the tail of the comet”.
On the other hand, mmk was worried that I won't be able to see the comet from Patagonia but I found that it is not so!
"In the southern hemisphere, on February 10, the comet will be about 1.5 degrees from Mars, according to Weather Thomas Prince, director of Caltech's WM Keck Institute for Space Studies..
That's about the width of your little finger when held at arms length. If you can locate Mars shining in the sky, look for the comet around it. However, The Virtual Telescope Project will offer a free live broadcast of the comet from 11:00 p.m. EST on its website and YouTube page."
