Debris points are tracked catalog objects from three selected fragmentation events, propagated from a dated CelesTrak GP snapshot with SGP4 into a two-hour Earth-fixed point ephemeris and one closed full-period display trajectory per object. This is not the full debris environment; point sizes are exaggerated and do not encode physical object size. Bright stars use Gaia DR3 celestial positions, G magnitude, and BP-RP color, with a restrained halo for the brightest stars. The Milky Way layer continuously reprojects the 2MASS infrared false-color Hammer map onto a celestial sphere. Both sky layers are oriented to the debris snapshot using GMST; their shell radius is display-only."
