Amalthea, also known as Jupiter V, is the third satellite of Jupiter. It was discovered on September 9, 1892 by Edward Emerson Barnard. It is located on one of Jupiter's rings called the Amalthea Gossamer Ring.

Composition

Amalthea is thought to consist of porous ice water under the surface, yet the ocean is too deep for astronomers to comprehend or spot. Astronomers believe that the icy ocean is too deep for any life to survive or thrive.

Surface

The surface of Amalthea is reddish, possibly due to sulfur from neighboring moon, Io, or other Galilean moons of Jupiter. With a surface brighter than those of the inner satellites of Jupiter, Amalthea has green patches on the surface, yet the nature or origin is currently unknown by astronomers. The surface is full of craters from previous impacts and collisions with other minor moons.
