Trans-Neptunian Object Illustration

Trans-Neptunian Object Illustration
This artist’s concept depicts a Trans-Neptunian Object (TNO), a small, faint, icy body orbiting the Sun beyond the orbit of Neptune. Often more than 100 million times dimmer than objects visible to the unaided eye, TNOs are so small that even with NASA’s Hubble and Webb space telescopes, they appear only as tiny points of light.

Image Description: An illustration of a roughly spherical, rocky object against a black background speckled with distant, white stars. The object is the color of red clay and is pockmarked with craters and other geological scars. At the bottom left corner of the illustration in gray lettering is the label “Artist’s Concept.”
