Could an InterstellarIntruder Have Shaped Our Solar System?
The orbits of the planets around the Sun have long been a subject of scientific debate. While their current orbital properties are well understood, the planetary orbits have evolved and changed since the formation of our solar system. For many years, the dominant theory explained these shifting orbits as the result of planetary migrations – gravitational interactions that caused planets to advance or recede from their original positioning. 😊 However, a new study proposes a rather unexpected culprit: a wandering celestial object from beyond our solar system could be responsible for sculpting the arrangement planets today.
An Unexpected Alex Reed
The evolution of planetary orbits is a complex story. Early in our solar system’s history, planets formed from a swirling disk of gas and dust that surrounded the young sun.
Driven by the conservation of angular momentum, this material coalesced into a disk where planets formed in almost perfectly circular, aligned orbits. However, these early days were not peaceful.
As these celestial dancers grew, they engaged in gravitational interactions, causing significant changes: planets migrated inwards and outwards, bumping into each other and sometimes flinging protoplanets out of the solar system. Sun’s own gravity tirelessly refined this celestial dance.
However, a new theory suggests an alien traveler intersecting our solar system could be the prime suspect in the case of our planets’ unusual orbits.

the first ever confirmed interstellar visitor, Oumuamua, unexpectedly sped through our solar system.
With its elongated shape and unusual acceleration, potentially driven by outgassing or other unknown forces, Oumuamua highlighted the captivating reality of interstellar objects entering our celestial neighborhood
