nomad

February 24, 2012

This image is an artistic rendition of a nomad object wandering the interstellar medium. The object is intentionally blurry to represent uncertainty about whether it has an atmosphere. A nomadic object may be an icy body akin to an object found in the outer solar system, a more rocky material akin to asteroid or even a gas giant similar in composition to the most massive solar system planets and exoplanets.
