caption_attribution_description: Jovian satellite Metis, imaged by the Galileo spacecraft
context_page_description: Metis or Jupiter XVI, is Jupiter's closest moon.
  Metis was found in 1979 by Stephen P. Synnott in images taken by the Voyager 1 probe. Its designation was S/1979 J 3. In 1983 it was named after the mythological Metis, a Titaness who was the first wife of Zeus.
  Metis is not a sphere and measures 60×40×34 km across. The composition and mass of Metis are not known, but assuming that its mean density is like that of Amalthea, its mass can be estimated as ~7×10¹⁶ kg. Amalthea's density implies that moon is composed of water ice with a porosity of 10-15%, and Adrastea may be similar.
  The surface of Metis is very cratered. It is dark and appears to be reddish in color.
