Hi and welcome to MoI.

Give this a shot. Click on the object you are interested in to select it, then click once on "reset" at the lower right side of the viewport controls. (These are invisible until you hover your mouse over them). Once you click "reset" the view zooms to fill the viewport with the selected object. Roll your mouse wheel (or use the zoom control) to pull back to a comfortable distance. Now, when orbiting, the selected object will be the center of rotation. This works even after you deselect the object.

Whew, takes longer to describe than to actually do!
