Oh man flying to planets manually is TOUGH, the physics engine is just realistic enough that doing it manually takes more skill than I care to develop.
Just use the autopilot. Yes, you have to be careful about not starting it when there's something else between you and your destination. But for real, use the autopilot.
Mind you, you are still going to die a lot because the universe is as amazing as it is unforgiving. You WILL die in that one specific way that will be your own damn fault because everyone does sooner or later. It's okay, and it's fun.
And it's very, very worth it.
For serious. I wish they hired remote.
