Every round object in the solar system, to scale (widescreen)
Global views of round worlds across the solar system taken by a dozen different spacecraft. The boundary between round and not-round occurs between around 400 and 600 kilometers' diameter, depending on the composition of the world. The trans-Neptunian objects in lower right corner are represented by artworks except for Pluto and Charon.
This montage was updated in January 2020 to include New Horizons images of Pluto and Charon.
