Definitely it's going to hit the Sun, more of 70 % of possibility for strong CME on opposite side of impact ..

Question is how match hi meltdown at this moment and what composition this comet is made ..

It's from Kreutz-group comets, so very possibility will have same influence on Sun like last bigger one from Kreutz-group comet ..
