| Feb 23, 2017 at 3:22 | comment | added | Selene Routley | @DavidZ There's probably a bit more to it than that, as one has to account (for current rocket technology) for the loss of kinetic energy to gravitational potential in escaping the Solar system: a classic Newtonian problem with definite physics content. So I'd be comfortable with the question's being left here. On the other hand, though, I would personally expect (if such a thought caught my mind) to be more likely to find this answer more on SE Stack Exchange than on Physics SE. | |

| Feb 23, 2017 at 2:41 | comment | added | lostsoul29 | I see! I think you're right, my question is vague about what exactly I want to know - not just the amount of time, but why and how. | |
| Feb 23, 2017 at 1:58 | comment | added | user146020 | No problem, the guy who wrote a lot of that book, Alan Bond, now works on hypersonic aircraft, its a well thought out book (I own a copy of the original report). I wouldn't worry about the d/v but David's suggestion makes sense to me. Its more Engineering than physics, as I think you think you worded your question too briefly and gave the impression you want a simple calculation, when you really want to know more about how we could do it. | |
| Feb 23, 2017 at 1:28 | comment | added | lostsoul29 | I don't believe this question deserves the downvote. A similar question that does not discuss significant technical details has received a far kinder, and useful, response. (I could not find that question before posting this one.) | |

| Feb 23, 2017 at 1:25 | comment | added | David Z | If you want to start a discussion, then Stack Exchange isn't really the place to do it, though you might have some success in our Physics Chat. However, if you just want to get an answer, this might be on topic at Space Exploration. | |
| Feb 23, 2017 at 1:22 | comment | added | lostsoul29 | What would be a better forum to post this question (to start a discussion)? | |
| Feb 23, 2017 at 1:22 | comment | added | David Z | This seems to be more a matter of the available technology than of physics. I don't see any physics concept in this question, except maybe a simple calculation of $d/v$ (given that none of the available travel methods are relativistic). | |
