Basically yes. The centre object would be the sun in this case. But there are several forces that influence the asteroids in their orbit (all the spaceobjects in this universe influence each other, except those that drift away from each other with the speed of light. But most of these objects, only have infinitesmal influence on a certain other object). So if you want to calculate the orbit of an space object vaguely right, you need to include all the objects that have a relevant force on the target object).

For asteroids in the asteroid belt, the most important grav. source is the sun. Than there is minimal influence of other objects, like planetoids (Ceres), planets (Jupiter) and so on.
But there is a problem, said formula (WG) doesn't work with more than two sources of gravity (because with more than 2 grav. sources, one need to somehow implement the position of the objects and their direction vectors). That may be calculated by using approximation algorithms, but I don't know how it is done.


On another note ... Pluto is not considered a planet anymore (now the solar system makes sense )
