I don't understand the question. If the close object is close enough, it can exert more force than any given large object at a given distance away. Similarly, if the object is massive enough, it will exert more force than a close object of given mass and distance.

But, here are some sites that might help:

For gravity at small distances:

http://www.aip.org/pnu/2006/split/788-1.html
http://www.stanford.edu/group/kgb/Research/gravity2.html

On the other side, we have:

(I've seen no case where light was bent by a close object, so this may be the example you were looking for - of course, is light an "object")
