"Comet Borisov December 8th"

Comet Borisov makes it's closest approach to our sun today. Being an alien comet (not from our galaxy) it has probably never seen sunlight.. Scientists are suggesting this may make Borisov behave in unexpected ways. Borisov's closest approach to earth will be on December 28th. Very interesting article.
