Jupiter conjoins Quaoar every 12.4 years; it's about the same with Pluto; and 12.8 years with Neptune. Jupiter and Uranus conjoin at 13.9 year intervals; Jupiter and Chiron average 15.5 years apart; with the Jupiter ~ Saturn conjunctions (Cronocrater) occuring after 19.9 years. This means that Jupiter made about 50 conjunctions with the outer planets during the 20th century. It is currently beyond the scope of this project to list all of those cycles. Most ephemeris have some form of aspectarian, by which the Jupiter conjunctions with the outer planets may be discerned.
Here are the conjunctions with Quaoar, as aspectarians have yet to include them.
Here also are two conjunctions with Pluto, one recent and one from the distant past of the early Piscean age; similar in that the Moon was also conjunct in both.
