It's easy to land in other planets! There are two ways: - Make an orbit in which at least match the orbit of the target planet at one point. Then we warp even a little after that point, and depending on our orbit is longer or shorter than the target planet orbit, try to trust forward o backwrd to macht it. Gotta watch it at any particular time appears a point where we are trapped by the target planet's gravity. - Calculate gradient between objective and planet Kerbin of direct launch so that when the periapsis of our orbit reaches the target planet orbit, is just the time when we are trapped by the target planet's gravity. For example, about 135 ° to Jool or about -120 ° to Moho.
