Decay of our population of 91 125 clones of 2012 DR₃₀ as a function of time. The left-hand panels show the decay of the number of surviving clones as a function of time, whilst those to the right show the same data as log-log plots. The upper panels show the decay across the full 4 Gyr of our integrations, while the lower plots show just the first 200 Myr of the evolution of our test particles. It is immediately apparent that 2012 DR₃₀ is moving on a dynamically highly unstable orbit, with fully half the test particles being ejected from the solar system within the first 75.5 Myr of the integrations. Such instability is not unexpected, given that 2012 DR₃₀s orbit crosses those of Uranus and Neptune.
