Galileo's best images of Thebe, Amalthea, and Metis On January 4, 2000, near its orbit periapsis, Galileo captured its highest-resolution images of three of Jupiter's four inner regular moons: Thebe, Amalthea, and Metis, imaged from 192,700; 237,700; and 292,600 kilometers away, respectively. The images have been enlarged from their original resolution to a common scale for comparison, and rotated to place north approximately up. Thebe is about 84 kilometers pole-to-pole; Amalthea, 128 kilometers; and Metis, 38 kilometers.

Here is the original data for the above images, with the addition of Galileo's best image of Adrastea.

Galileo's highest-resolution images of Jupiter's ringmoons
From left to right, the moons are Metis, Adrastea, Amalthea, and Thebe. All of the images except Adrastea were taken January 4, 2000; Adrastea was taken on December 19, 1996.
  • Galileo imaged Metis from a distance of 292,600 kilometers, and a resolution of 2.97 kilometers per pixel.
  • Galileo imaged Adrastea from a distance of 658,100 kilometers, and a resolution of 6.69 kilometers per pixel.
  • Galileo imaged Amalthea multiple times. This is the highest-resolution image, taken from a distance of 237,700 kilometers, and a resolution of 2.42 km/pixel.
  • Galileo imaged Thebe from a distance of 192,700 kilometers, and a resolution of 1.96 km/pixel.

Original image data dated on or about January 4, 2000.
