- TL;DR Summary
- What metric would one use to describe spacetime around multiple massive objects?

In describing the spacetime around a massive, spherical object, one would use the Schwarzschild Metric. What metric would instead be used to describe the spacetime around multiple massive bodies? Say, for example, you want to calculate the Gravitational Time Dilation experienced by a rocket ship between two different stars (where everything in the system is stationary with respect to everything else for simplicity). How would you go about doing that?

Similarly, is there a metric that can calculate the warping of spacetime from arbitrary amounts of masses or around objects that aren't spherical (perhaps by approximating the object as a collection of point masses)?
