LROC NAC frame showing a string of secondary craters from an impact crater to the north, probably Giordano Bruno. [NASA/GSFC/Arizona State University].
LROC News System: A northwest-trending string of fresh secondary craters formed by debris thrown out of a larger impact, most likely Giordano Bruno (525 km to the north). The chain is about 4.5 km long and the largest crater at the southeast end is about 340 m in diameter. The morphology of the impact suggests that the debris impacted the surface at a low angle, heading to the south. Smaller pieces at the northwest end churned and scoured the surface while the larger pieces at the southeast end formed round craters. Secondary craters are common on the lunar surface and occur both in chains and as isolated small craters. It is easy to identify secondary craters when they form in chains, but it is much more difficult to distinguish individual secondary craters.
