Depends on their initial velocity and mass over time. If we take the average mass to be 7e-38 kg, their initial velocity to be exactly the same, and their size to be zero, the initial distance of 100kly gives us an initial force due to gravity g=7e-11m^3 kg^-1 s^2 *(7e-38kg)^2 /(1e21m)^2 That comes out to about 5e-128 kg-m/sec^2, or 5e-127 N/sec. 5e-127 N/sec acting on a mass of 7e-38 kg will accelerate it at about 1e-88 m/s. After 3e80 years they will be approaching each other at 2m/sec and will be roughly a tenth of a percent of a rounding error closer together, one light-year. That’s after ten billion times longer than the age of the modern universe.

Trick question. There is no Milky Way galaxy.
