There’s no north or anything, are there coordinates or you just point at a planet and go for it?
In: Physics
Navigation and positioning in space (far from earth) is typically done by tracking your position as it relates to stationary or plotted objects like stars or planets https://en.wikipedia.org/wiki/Star_tracker
In summary, you see specific planet out a specific window, this acts as a point of reference, with a few you can triangulate, with computers doing calculations many times a second it can be very accurate.
There are other methods too, including Transponder pings, GNSS sattelites, inertial sensing, dead reckoning, etc https://en.m.wikipedia.org/wiki/Positioning_system
and yes when “aiming” for a specific planet, you actually aim at empty space ahead of it’s path, to intercept catch up to it months later on opposite side of solar system at good angle and speed
