NO BODY can predict an accurate arrival time, astro-physicists cannot, in fact, they cannot even accurately predict the path or travel itinerary of common asteroids… scientists use words such as expect, predict, within (so many thousands of miles), may pass close to earth, may not, so on and so on and so on. SO WHY DO YOU TROLLTARDS ALWAYS HOLD THE NIBIRU TRACKERS TO EXACT PRECISE DATES AND DISTANCES ON OBJECTS THAT ARE NOT COMMON? Whether you believe in NIBIRU is not the issue. The evidence continues to mount against the nay-sayers and, we now know that NASA is covering up the Truth. So go ahead you worthless Trolls, jack your thumb down as usual.
