DART impact (Dimorphos) is catalogued in this registry as an impact-site, held in the frame of Dimorphos, from Artificial impact sites (curated).

provenance PROCESSED — derived deterministically from source catalogues (unit, frame and epoch conversions, cross-source reconciliation) — no value invented

Open DART impact (Dimorphos) in the live scene → The scene composes a position for any date and is where a figure becomes a picture. It downloads the whole catalogue first: measured against the built product, an object outside the core resolves after about 16 s over a local network and about 147 s over a 4 Mbit link, having transferred roughly 70 MB. If you cannot wait that long, this page is the answer.

Kinetic planetary-defence test; struck Dimorphos, the moon of Didymos, at 6.1 km/s. The scar sits on DIMORPHOS itself since that node exists — before, it was drawn on the primary, 1.2 km away and on the wrong body. Site 264.3°E, −8.8°N in the Dimorphos body-fixed frame [Chabot et al. 2024, PSJ 5, 49]. ⚠ ONE APPROXIMATION REMAINS, and it is stated rather than left to be found: the node carries no rotation model, because the body was tidally locked before the impact and was left tumbling after it with no published post-impact pole — so the mark is placed in an ecliptic-aligned body frame and its position ON the 150 m body is not the published longitude. · WHAT THE IMPACT THREW: 104 boulders were tracked in LICIACube/LUKE images from 29 to 243 s after the strike — radii up to 3.6 m, speeds up to 52 m/s, thrown into a roughly 135°×100° cone directed south, nearly perpendicular to DART's own trajectory. Their combined momentum exceeds the spacecraft's own by more than a factor of three, so humanity's first act of planetary defence sent away more momentum in rock than it carried in. These are the published BOUNDS of the swarm, not a table of 104 objects: the individual 3-D states are the authors' derivation from image positions, and the registry does not hold them.
