...found it! "Cruithne" more of an asteroid that zooms out of reach of the Earth and crosses the path of at least 2 other planets before zooming back again. See the link below:

I think there's some dispute about whether Cruithne is actually a moon or not because it has no gravitational connection to the Earth. Anyone know whether this is true?

As far as I know there is no dispute. Cruithne has an orbit around the sun that lasts almost exactly a year but this orbit is not on the planetary plane; far from it. So it hardly ever crosses the path of the Earth.
