Himalia[edit | edit source]
Mean orbit radius of Himalia around Jupiter is 11,460,000 km[1]
Period is 250.56 d (0.704 a)[1]
"Unfortunately the numeration of Jupiter's satellites is now in precisely the same confusion as that of Saturn's system was before the numbers were abandoned and names substituted. A similar course would seem to be advisable here; the designation V for the inner satellite [Amalthea] was tolerated for a time, as it was considered to be in a class by itself; but it has now got companions, so that this subterfuge disappears. The substitution of names for numerals is certainly more poetic."[2]
The moon was sometimes called Hestia, after the Hestia the Greek goddess, from 1955 to 1975.[3]
At a distance of about 11.5 million km from Jupiter, Himalia takes about 251 Earth days to complete one orbit.[4] It is the largest member of the Himalia group, the moons orbiting between 11.4 and 13 million kilometres from Jupiter at an inclination of about 27.5°.[5] The orbital elements are as of January 2000.[1]
