The 2 stars are about the same distance from the GC.
The latest estimate of the distance from the Sun to GC is 26,000 (± 1400) light-years.

Where did you get that information? Any idea what the time lag would be between the arrival of light and the arrival of debris? I’m wondering what our window is to set up defensive measures.
