No yet, that is a lot of mass but the solar system is a big place so maybe we and the debris of a 10,000k comet will not meet any time soon. Still that a lot of mass floating around the inner solar system.
If the 10,000k is true, and I still can't believe it. Then the comet is bigger (alot) than the earth! No frigin way a comet bigger then the earth can enter the inner solar system and all hell not break loose. I do not believe the size estimate. Must be a mistake.
Duh, I see that you identified it as Comet Linear, the Earth will pass through its tail on May 17.
