Summary:
- Astronomers have discovered a strange new object in our solar system that is orbiting and "dancing" with the planet Neptune.
- This object, nicknamed "Neso," is a small, icy body that takes about 27 years to complete one orbit around the Sun, following a complex path that keeps it in sync with Neptune.
- Neso's unusual orbit and behavior provide clues about the early formation and evolution of our solar system, and may help scientists better understand the dynamics of distant objects in the outer reaches of the solar system.
