So I need to keep an eye on the planets..and when they are drained move the harvesters to a new place?

Yeah this could be a manual lol.
It has helped me tremendously!

I just leave the harvesters set to the planets. Like I said, they'll keep harvesting as the planet keeps generating resources.

If you're hurting on your Object count you can use one harvester per colony system, but that requires ALOT of micromanaging. And believe me, I mean a lot! But if you can spare it, and I suspect you can, as the 'ole RTS "Rush" doesn't really work in this game, you should keep one Harvester per outpost. It makes your life a lot easier.
