December right? Unless I wasn't paying attention to entire vid, didn't they say that they are not sure if its path will be bend and it will survive sun's rendevouz, or it will be "swallowed" by it. But, if they don't know that, they cannot know if, upon bending/surviving, it won't get on its path with Earth, right? Wouldn't they know already?
