Anonymous2: I was just thinking about this thing: what is the minnimum amount of Δv on a liquid-fuel based rocked (or Ion) needed to get an escape trajectory out of the Sun, (or just to the Oort cloud/Kuiper belt) using gravity assists, mostly from Venus/Earth. While i was writing this, ive remembered about Voyager 1 and 2 which got out of the solar system with only about 2km/s Δv. But it didnt use venus or earth. Only Jupiter and Saturn. So my question is: is it possible, for planets to perfectly allign to make such a voyage possible? (e.g. Venus-Earth-Mars-Venus-Mercury-Venus-Earth-Jupiter-Saturn-Uranus-Neptune) Intersting idea for sure.
