The 250-km-wide body is the smallest object known to have rings, and observations show they're evolving.
What to know
- Chariklo is the smallest known body to possess rings, measuring roughly 250 kilometers in diameter.
- Observations spanning the past decade show measurable changes in the asteroid's two rings.
- The findings suggest ring systems around small bodies are dynamic and subject to evolution.
“Chariklo is only about 250 km across, but it has two rings, and they're changing.”
