Amalthea (J-V) is the third-closest moon of Jupiter and the
largest of Jupiter's smaller moons. It is a small, red, elongated,
cratered moon (with two very large craters); it has the fastest
speed of any known moon. It is potato-shaped, with dimensions: 145
x 91 x 83 miles (232 x146 x134 km). Its mass is 7.17x1021kg.
Amalthea's mean distance from Jupiter is 181,300 miles. It takes
Amalthea about 12 hours to orbit Jupiter; like most of Jupiter's
moons, it is in synchronous orbit. It was discovered and named in
1892 by the American astronomer Edward Emerson Barnard.
