We calculated these events for the bright outer planets for -100 till +3000 AD. No cases are founf before the 24th century. For Uranus 1850-2050 there are 4 cases, two of them in the 20th century. The rarity of the events in the present time can be explained by the fact that they occur in clusters separated by long-term periodicities.
