I mean, we are finding Pluto sized objects right outside our solar system all the time now.

  You forget how big space is.

  It doesn't seem like it's all the time. Pluto is the largest, Eris is close. Haumea, (225088) 2007 OR10 and Makemake are the only others at least 1/2 the diameter of Pluto. We are finding more trans-Neptunian objects. There's about 2,500 of them. But as Adams said, "Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is." Voyager can only be angled a smidgen from it's current path. There's nothing it can reach to do a slingshot. If Voyager could change its path by 0.1 degree (which it can't), and if all of the trans-Neptunian objects were equally distributed around the Sun (which they aren't - and Voyager is going out of the plane of the ecliptic), then that's still only a 0.2% chance of having something in its path. Even if there were, Pluto gave New Horizons about 5-6 m/s boost. That's effectively nothing compared to Voyager's 17 km/s speed. https://www.youtube.com/watch?v=Hm6ga-g9ACU https://www.youtube.com/watch?v=Hm6ga-g9ACU via https://space.stackexchange.com/questions/10087/did-the-pluto-flyby-give-new-horizons-any-significant-gravitational-boost https://space.stackexchange.com/questions/10087/did-the-plut... .
