Beyond this, we didn't even know for sure there was a massive object
in trojan with the Earth until very recently, and we had no idea Pluto
had at least 5 moons until we went out there.

Going part-way out there did not make it possible to find them, except
in so far as the intention of going past there makes it desirable to
look for such. "We" have not yet gone to Pluto, though New Horizons can
no longer avoid the Plutonic region.
