The interval between the fourth and third impacts is a bit longer. The fragments of Comet Arthur hit the sun from one direction. If you want to ensure that the impact range covers the entire sun, then some fragments must fly for a while, and then circle the side or the back of the sun to collide.
The fourth fragment is faster and has a more outward orbital angle. So the fourth fragment was flying at a speed of 438 kilometers per second at a distance of just over one million kilometers from the sun. During the flight, it became more and more distant from the sun. Getting closer, getting closer, and finally hitting the sun at an extremely inclined angle...
Alex could not imagine what kind of picture he would see if he stood above the sun to watch the process. Alex raised his head again, his eyes crossed the wall again, aiming at the sun in the void, his eyes were distant and calm.
