In order to get something there fast enough it would be traveling out very fast. Getting something there to orbit I think is not realistic for us any time soon.
replyI guess the point he's making is that the orbital velocity is pretty slow, so it's not too different to "get there" and "orbit there".
replyOf course, the rocket equation often makes "just add a few percent more delta V" pretty hard ;)
> so it's not too different to "get there" and "orbit there".
replyBut to "get there" within any reasonable timespan requires going really fast - which is currently highly impractical. And then once you get there, you have to them cancel pretty much all of that velocity which is not just a "few percent more delta V".
We can do 7-8 AU per year right now using tech we have. Voy 1 and Voy 2 are moving at 3.59 and 3.25. A starship sized rocket could also possibly get a small payload that separates to 15 AU. This is all using conventual propellent. If you consider using nuclear explosive as a prepulsion technique the math starts to change substantially and you can achieve even 25 AU / year.
