Is the throwing of objects limited only to the 4 spaces and 6 spaces for heavy objects and light objects, respectively, or can you throw it up to a character's range?

Like Superman, for instance. I know he can throw a small island into orbit; can he throw a gum-ball machine 8 spaces, or only 4?

You were correct at first with Super Strength you can throw an object 4 spaces for heavy objects(dealing 3 damage) and 6 spaces (dealing 2 damage) for light objects.

I assumed as much, but just checking. Thanks.

except one light 3-D object - namely Crate - I believe that it gains +2 range. Correct me if I am wrong.
