Our solar system is a case in point: the latest exoplanet research suggests that its orderly arrangement of planets is exceptionally rare, with rocky planets closer to the sun and
gas giants farther out.
For years, astronomers expected to see elsewhere what they saw in our own orderly solar system: rocky planets close to a star and

The basic architecture of our solar system, where things go in circles, and there are small rocky planets close to the sun and big massive
gas giants far from the sun, is certainly not the only architecture.

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.
