Seems Oumuamua was just a day tripper in comparison. Not even a full day, just nipped in for an ice cream then out again.

2015 BZ509 orbits the sun in the retrograde orbit in comparison, shares Jupiter orbit. The reckon it is been here since we started. We as in solar system.

Guessing as it is going the wrong way.

Typically the solar system formed from a mass that was spinning the same way. Venus goes around the sun the same way but it spins the other way to the rest of us. Triton orbits the wrong way but some theory that it is also a captured object.

I think.

Guessing that the few that Jupiter has etc. are captured, however I understand this is not a moon but an object going the wrong way.

Edit. They have been quick on wiki,

I suppose the only way to be sure is go get a sample. However they did say they ran back in simulations and the orbit works, though I understand that Jupiter was a bit of a hooligan in its yoof and one theory is it took a wander through the solar system. Obviously not for the hell of it but part of the early formation.

Edit. The "they" are in here
