| COMETS, JUPITER IMPACT AND THE OORT CLOUD | By Miss_Miracle1410
Many of you might know what comets are...but maybe you would like seeing it from my perspective!
Comets are lumps of dirty ice that make long journeys through space. And as they approach a star or the Sun (in our case because technically we are still talking from inside the solar system)- they melt creating the long tails of gas and dust which had been frozen for many years.
Now Aristotle, a Greek philosopher was first to lay foundations of the first ideas that these icy rocks are harbingers of bad luck. His understanding of the physical nature of comets, was deeply rooted in his interpretation of the astronomical bodies having ominous significance. Basically, he wanted to say that whenever the comets passed by our planet bad things happen and it could be used to detect droughts, earthquakes and prodigious rains and later it was also connected to diseases, wars, treachery, civil discord and much more.
I wouldn't be surprised if a comet had passed by during world war years.
So many of you might be wondering what Jupiter got to do with all these Comets orbiting the Sun. Being the biggest planet in the solar system, Jupiter seems to attract a lot of attention solely due to its strong gravity and it is hit much more often by comets than other planets are. In 1994, comet Shoemaker-Levy 9 (I'm not making this up... That's really the comet's name! ) broke up and many of its fragments crashed into Jupiter, leaving disturbances in its atmosphere.
Now coming to Oort clouds...
Some comets come from the Oort cloud, which is the outermost part of the Solar System. Others come from the Scattered Disc, an area outside the Kuiper Belt (it is similar to the asteroid belt between Mars and Jupiter, we have an asteroid belt after Pluto marking the border of the solar system).
Comets start to move towards the Sun from the cloud or disc when they are disturbed by the gravity of other objects. Oort Cloud comets are disturbed by passing stars, while it is the outer planets that affect the Scattered Disc.
Edmund Halley realized that some comets return regularly to Earth. He read historical records and predicted one comet, now named after him... (yeah that's right) the most famous comet Halley's Comet would return in 1758. Sure enough, it did. The last time it visited Earth was in 1986 and by then it received a lot of attention.
▪️And here's a fun fact▪️ The most logical reason for why this year hasn't been much to our likings is because of a comet which will be visiting us in the near future.
