An Alien Planet May be "Hiding" in The Oort Cloud

A 'captured' alien planet may be hiding at the edge of our solar system — and it's not 'Planet X'
A recent study suggests that the Oort cloud, situated at the edge of our solar system, might be concealing a rogue exoplanet.
Researchers simulated the early solar system's unstable celestial mechanics and hypothesized the possibility of planetsized bodies resting within the Oort cloud.
The cloud, a collection of icy objects, is situated several hundred billion to trillion miles from the Sun.
Scientists postulate that there's a 0.5% chance of a rogue planet originating from our solar system being in the Oort cloud, while a 7% chance exists that a Neptunesized rogue planet from another solar system was captured by the Sun's gravity and resides there.
The paper awaits peerreview and is published on the arXiv preprint server.
