Can't get to asteroid [Noob & Using Mechjeb]

[NateDaBeast]

Ok, my strong impression here now is that you understand very little about how to plan orbital manoeuvres in KSP and are looking for a very in-depth explanation of how it's done. I recommend you forget asteroids for now and use one of the tutorials for intercepting another planet (of which there are many on youtube, google and here) and then try to apply that knowledge to intercepting an asteroid (which is actually much more difficult because asteroids are so tiny).

Also, while I totally defend your choice to play using MechJeb for everything, as I've tried to explain, there are limits to what it can do. You may find that forgetting MechJeb and learning the old fashioned way is much more enlightening.

Also, if you get a report that says some gibberish you don't understand, try looking up the key terms, e.g. eccentricity. This, for example, basically means how circular your orbit is (more eccentric is less circular). A simple solution: if MechJeb gives that warning, would be to circularise the orbit first and then try for the intercept/transfer.

While the forum community will be happy to help with specific problems, I can't help but feel you're asking for a lot of help with things that you'd probably work out on your own with a bit more practice.

Okay thanks for the tips !
