Part 13/15:
While the traditional visualization of the Oort Cloud was as a perfect sphere, recent research upended this notion. In 2025, scientists conducted detailed simulations considering the complex gravitational influences at play: the Sun’s gravity, the effects of nearby stars, and the gravitational tide of the Milky Way.
The result? The Oort Cloud is not a static, uniform sphere. Instead, it exhibits a spiral-arm structure, akin to a tiny galaxy wrapped around our Sun. The galactic tides and the gravitational influence of passing stars distort and shape the cloud over billions of years, giving it a complex, dynamic form rather than a simple, spherical shell.
