> Ultima Thule was a studied object, targeted by an serious AF NASA interplanetary mission... It was targeted by New Horizons project well after the spacecraft lauched in 2006. Ultima Thule was only discovered in 2014 !! Sadly for Oumuiamua, this thing was detected far too late to do intensive observations, it's on the way out of the solar system if I understand correctly.
