The farther a planet is from the Sun, the slower the orbit is. So close to the Sun it would go very fast. What would happen if we fire something from the Earth in opposite direction of Earth's orbit. I understand it would not hold in orbit but start falling towards the Sun, accelerating because of the fall. My guess is, this acceleration means it would then reach another stable orbit, closer to the Sun. This is not explained in the text (the video glances on it). What it says is “Anything short of that just puts the spacecraft in an elliptical orbit that never hits the star.” -- Cheers, Carlos. ES🇪🇸, EU🇪🇺;
