As an initial test of the Planet V hypothesis, Chambers and Lissauer conducted 36 computer simulations of the Solar System with an additional terrestrial planet. A variety of parameters were used to determine the impacts of Planet V's initial orbit and mass. The mean time at which Planet V was lost was found to increase from 100 Myr to 400 Myr as its initial semi-major axis was increased from 1.8 to 1.9 AU. Results consistent with the current Solar System were most common with a 0.25 Mars mass Planet V. In cases with a larger mass Planet V collisions between planets were likely. Overall a third of these simulations were deemed successful in that Planet V was removed without impacting another planet. To test whether Planet V could increase the lunar impact rate they added test particles to one of the simulations. After an initial decline the number of particles on Earth-crossing orbits increased after Planet V entered the inner asteroid belt a pattern consistent with the LHB. These results were presented at the 33rd Lunar and Planetary Science Conference.
