"Simulations Suggest 5 Earth-Like Worlds in Solar System's Outer Reaches"

TL;DR
New research suggests that up to five Earth-like rocky planets may be present in the outer reaches of the solar system, potentially captured by the sun during its infancy. These free-floating planets, which could be as big as Mars, are theorized to reside in the Oort Cloud, a distant region of the solar system. While their habitability remains uncertain, future space missions may target these exoplanets, and the Vera C Rubin Observatory in Chile could potentially identify them when it goes live in 2025.
