Editing Planet V (section)

==Alternate version==
An impact of Planet V onto Mars, forming the Borealis Basin has recently been proposed as an explanation for the Late Heavy Bombardment. Debris from this impact would have a different size distribution than the asteroid belt with a smaller fraction of large bodies and would result in a lower number of giant impact basins relative to craters.<ref name=Minton_etal_2015>{{cite journal|last1=Minton|first1=D.
