So, according to wikipedia this thing has a perihelion of 1.143164 AU. The Earth has an aphelion of 1.0167 AU.
Can someone please explain how this thing ever gets closer than about 11 million miles from earth in its current orbit?

Considered as a pair of two-body dynamic systems, you cant. But if this thing gets close enough to another heavenly body (Mars?) you then have a three-body problem - which is notoriously difficult to solve in closed form. In such case you could see the orbit of this thing changed - and its perihelion reduced.
