Question: is it possible for a sun explosion to be so big that it hits the earth???

Yes, definitely! And they don’t have to be that big! Even weaker ones can hit the Earth, but they just take longer to get here. As long as they come from the part of the Sun facing the Earth, they can and do hit us! But don’t worry, only the stronger ones cause problems for satellites and they also cause pretty things like the Northern Lights!
