- Similar to the effects of a thick atmosphere, a vertical column of water would also inhibit the formation of impact craters from smaller impactors.
- The impactor and comet will collide at 10.2km per second, releasing the energy equivalent of 4.4 tonnes of exploding TNT.
- The close dates of the major impact basins suggested that the Moon experienced a late, heavy bombardment of large impactors around 3.8 to 4 billion years ago.
- Although dramatic images of the impact may be sent to Earth in near-real time by the Deep Impact spacecraft and its impactor, the spacecraft themselves have limited remote sensing capability.
