Displaying objects of various sizes

I have a small problem - I am using Unity to make a visualisation and I have to display two objects: one that is near and is really big (like, 20 meters) and the other one that is really far (like, 150m further) and it's size is around 5-10 cm. Is it even possible to have object with such various sizes and so far apart displayed? If yes - I had two ideas on how to do it:

1. Split the screen so that one would show big element and the other the small one. That would be the best. But, either way, they have to be in the same space, so if I would have a line connecting them it would have to be displayed in both.

2. Make a key shortcut to move the camera between two predefined positions.

I am pretty new to all this so any help would be greatly appreciated.
