• The smallest TNO observed has a diameter of about 3 miles (5 kilometers). ^[1]
• The researchers analyzed the color, composition, and size distribution of 27 newly discovered tiny, dim TNOs. ^[1]
• Most TNOs are more than 100 million times dimmer than objects visible to the unaided eye. ^[1]
• NASA’s Hubble and James Webb Space Telescopes were used to study Trans-Neptunian Objects (TNOs). ^[1]
