Trans-Neptunian Object, illustration. Most trans-Neptunian objects (TNOs) are small and faint, making them difficult to spot. Generally, they are more than 100 million times fainter than objects visible to the unaided eye. The Sun (upper left) is seen as a bright star at a distance of about 5 billion kilometres. | |
