Say you have two masses in an otherwise empty space and you can approximate the metric near each mass as a Schwarzschild (or whatever). Is there a way of combining or 'stitching together' these two metrics to give the overall metric of all spacetime?(adsbygoogle = window.adsbygoogle || []).push({});

I'm just interested to know how a test particle could move in a space where there are two (or more) point masses but don't know how to calculate the overall metric of such a space.
