A massive object may have drifted into our solar system billions of years ago .

This event could explain the unusual orbits of planets in the solar system.

The chances of such an encounter happening are slim— between 1 in 1,000 and 1 in 10,000 .

This hypothesis isn’t just theoretical. The galaxy is teeming with rogue planets and star clusters.
