Orbital speeds. Remember earth and by consequence everything on it is moving at 30km/s. Most efficient way to hit the sun is to cancel that out, or decelerating until your velocity relative to the sun is 0 and then gravity does the rest of the work. Orbiting a stellar object is missing with flair. It’s easier to entirely miss the sun by accelerating at roughly 12 Km/s additional velocity which will allow you to escape the sun’s gravity. Or 40% of the delta V (more velocity is not linear fuel expended either, more exponential with needing roughly 99x more fuel to do one than the other… not even accounting for the chase of now accelerating that fuel weight.)
