Three Dimensional

They only talk about one alignment from the sun.  We don’t think they even reveal all the planets. Saturn means seven and it is the sixth planet of the alignment which NASA gives.  The sun is three dimensional.  There ae planets situated all around it.   How many planets are in use around this sun?  We know Saturn has people. Probably many on this planet have been to Saturn first.  That’s two planets inhabited that we know of,  There must be more.
