 This text seems more than a little uncertain: 

 * has an orbit with extreme eccentricity (~0.9), bringing its perihelion near Saturn's orbit. This qualifies it as a Centaur. 

  and I have been discussing the whole 1999 TD10 issue and trying to figure out where to come down. I have quite literally found contradicting sources: some say centaur, some say SDO... so perhaps the best thing would be to remove it for now, but actively pursue this question on the talk page. Since  weighed in as well, I think it's best to remove the text from the article and research this question more thouroughly. So that's what I did. -) .
