how to enter another planets orbits

[skyraider74]

ive only been to the mun and minmus, how do i exit kerbin orbit and enter duna or eves orbit. I tried creating a maneuver but it never lined up, pls help.

the most simple way is to do it the same way you get to the mun/minmus except around the sun. leave kerbin sphere of influence, make a maneuver around the sun to target planet's orbit, move maneuver around until you get an encounter. this is terribly inefficient and slow however


the most effective way is a hohmann transfer maneuver directly from kerbin orbit, which requires both kerbin and your target planet to be at a very specific angle to each other relative to the sun before executing a burn, which itself is done at a specific angle on your parking orbit around kerbin

what those angles are depends on the planet

for example, kerbin>duna requires a 44.3 degree angle between kerbin and duna relative to the sun, and your maneuver is at 150.91 degrees from kerbin's prograde.


https://ksp.olex.biz/ gives you a more in depth rundown, and also a calculator you can use. it only works on the stock KSP system though, so no planet pack mods



go for eve as your first target as it's the easiest one to hit. just don't go there expecting to land and return

Use the calculator. I don't recommend Eve but rather Duna. You should be ready to land there and return home pretty easily if you've already done most of Kerbin"s moon's science. Maybe do a bit of research in your Tracking Station to help you know what you will need.

i am not a master at interplanetary, but burning retrograde at periapsis will( well it should) get you into an orbit. then when in an orbit stop

The latest version has a built in planner tool you can use, once in orbit. Use it.

To make it super simple.

Launch straight up at sunset to go to the inner planets like Eve, Moho

Launch straight up at sunrise to go to the outer planets like Duna, Jool etc

Set target in map screen and once you reach escape you will see your new orbit around the sun change. Try to get it closeish if you can or see where you are at relatively speaking then...

Once in orbit around the sun use navigation nodes to plan the fight.

When you orbit Kerbin, and Kerbin orbits counter clockwise around Kerbol Sun..

1. if you exit Kerbin orbit towards the path Kerbin came "FROM" (behind, or a location in the past), then your exit allows you to have a smaller orbit closer to the inner planets for a smaller cost.
2. if you exit Kerbin orbit towards the path Kerbin is headed "TO" (ahead, or a location in the future), then your exit allows you to have a larger orbit closer to the outer planets for a smaller cost.

update: orbiting kerbol and doing maneuvers from there is the only thing i can do. I sat there for 4 hours using the caculator and i was so frustrating and nothing lined up. I even wrote angles on paper and nothing happened.
