Buffy (2004 XR190)

2004 XR190, nicknamed "Buffy," is a unique trans-Neptunian object (TNO) with an unusual orbit. It's located in the outer region of the Solar System and has a high inclination and a relatively low eccentricity.  

Here are some key features of Buffy:

• High Inclination: Buffy's orbit is highly inclined, meaning it's tilted significantly compared to the orbits of most other planets and TNOs.  

• Low Eccentricity: Despite its high inclination, Buffy has a relatively low eccentricity, meaning its orbit is nearly circular.  

• Large Perihelion: Buffy's perihelion, or closest point to the Sun, is beyond the reach of perturbations from the giant planets.  

• Unusual Orbital Dynamics: Its unique orbital characteristics have led scientists to propose various theories to explain its formation and evolution, including interactions with a passing star or planet.  

Buffy's unusual orbit makes it a valuable object for studying the dynamics and evolution of the outer Solar System.

It challenges our current understanding of how these distant objects formed and migrated to their current positions.
