Given the large orbital eccentricities of these two objects (which move beyond 500 AUs of the Sun), some astronomers have argued that they were likely to have been strongly perturbed by a massive celestial object (which is unlikely to have been Neptune as they do not come close enough to feel its gravitational influence) such as the passing of a rogue planet (perturbed from its primordial orbit by the gas giants of the inner Solar Sylstem) or one or more passing stars, which could have dragged the two objects farther out after initial orbital perturbation by Neptune or as part of a «first - generation» Oort Cloud.

A collision between two large galaxies is usually the cause of such starburst phases, where the cold gas residing in the giant molecular clouds becomes the fuel for sustaining such high rates of star formation.

Both objects formed among the rocky and icy protoplanets beyond the Solar System's «ice line» now located around 2.7 AUs, but the early development of Jupiter apparently prevented such large protoplanets between the gas giant and planet Mars from agglomerating into even bigger planetary bodies, by sweeping many into pulverizing collisions as well as slinging them into the Sun or Oort Cloud, or even beyond Sol's gravitational reach altogether.

Under one popular theory (Boss, 1995), if such protoplanets become sufficiently massive while there is still abundant amounts of hydrogen and helium gases remaining in the disk, then they may accrete substantial amounts of those gases and become so - called gas giants (like Jupiter, Saturn, Uranus, and Neptune in the Solar System).
