"Maximum Distance Exceeded" error when plotting course for passenger mission in Elite Dangerous

I got a passenger mission, where the destination is more than 5,000 light-years away. I'm trying to plot a course to the destination, in the Galaxy Map, but I'm getting an error saying "maximum distance exceeded." How do I get to my destination?

Hyperspace jumps can only be plotted out to 1,000 light-years, so you'll need to find a star that's just under 1,000 light years away from your current location. Once you reach that destination, or a bit before then, plot your next 1,000 light-year segment, until you get there.
