Ixion

Ixion is a large trans-Neptunian object (TNO) and a possible dwarf planet located in the Kuiper belt. Here are some key facts about Ixion:  

• Size: Ixion is one of the largest known TNOs, with a diameter estimated to be around 1,200 kilometers.

• Orbit: Ixion is a plutino, meaning it is in a 2:3 orbital resonance with Neptune. This means it orbits the Sun twice for every three orbits of Neptune.  

• Surface: Ixion's surface is relatively dark, suggesting that it's covered in dark organic compounds.  

• Discovery: Ixion was discovered in 2001 by the Deep Ecliptic Survey.  

Ixion's large size and dark surface make it a fascinating object for study. It provides valuable insights into the formation and evolution of the Kuiper Belt and the early solar system.
