This finding explains the discrepancy between the number of basins detected on the Moon (~40) and the number predicted (~300) by an accretion scenario of planet formation.

planets have been slowly appearing to shift across the sky — partially because of our orbital motion around the sun and partially because of the motion of the inner planets," Pitts said.
