木衛(wèi)的外層衛(wèi)星(中英)

字號(hào):

Farthest from Jupiter (outward of the Galilean moons) are the eight tiny moons: Leda Ananke
    Himalia Carme
    Lysithea Pasiphae
    Elara Sinope
    Jupiter's eight outer moons fall into two groups: Leda, Himalia, Lysithea and Elara at about 11 million km from Jupiter and Ananke, Carme, Pasiphae and Sinope at about 23 million km. When the first version of The Nine Planets was written that was it. But in recent years several dozen tiny moons in various orbits farther out have been detected.
    Leda
    Jupiter XIII
    Leda is the ninth of Jupiter's known satellites and the smallest:
    orbit: 11,094,000 km from Jupiter
    diameter: 16 km
    mass: 5.68e15 kg
    Leda was queen of Sparta and the mother, by Zeus in the form of a swan, of Pollux and Helen of Troy.
    Discovered by Kowal in 1974.
    Leda, Ananke, and Sinope are among the smallest moons in the solar system.
    Himalia
    Jupiter VI
    Himalia is the tenth of Jupiter's known satellites:
    orbit: 11,480,000 km from Jupiter
    diameter: 186 km
    mass: 9.56e18 kg
    Himalia was a nymph who bore three sons of Zeus (Jupiter).
    Discovered by Perrine in 1904.
    Unlike the inner satellites, the orbits of Leda, Himalia, Lysithea and Elara are significantly inclined to Jupiter's equator (about 28 degrees).
    Lysithea
    Jupiter X
    Lysithea is the eleventh of Jupiter's known satellites:
    orbit: 11,720,000 km from Jupiter
    diameter: 36 km
    mass: 7.77e16 kg
    Lysithea was a daughter of Oceanus and one of Zeus' lovers.
    Discovered by Nicholson in 1938.
    Elara
    Jupiter VII
    Elara is the twelfth of Jupiter's known satellites: orbit: 11,737,000 km from Jupiter
    diameter: 76 km
    mass: 7.77e17 kg
    Elara was the mother by Zeus of the giant Tityus.
    Discovered by Perrine in 1905.
    Leda, Himalia, Lysithea and Elara may be remnants of a single asteroid that was captured by Jupiter and broken up.
    Ananke
    Jupiter XII
    Ananke is the thirteenth of Jupiter's known satellites:
    orbit: 21,200,000 km from Jupiter
    diameter: 30 km
    mass: 3.82e16 kg
    Ananke was the mother of Adrastea, by Jupiter.
    Discovered by Nicholson in 1951.
    Ananke, Carme, Pasiphae and Sinope have unusual but similar orbits.
    Carme
    Jupiter XI
    Carme is the fourteenth of Jupiter's known satellites:
    orbit: 22,600,000 km from Jupiter
    diameter: 40 km
    mass: 9.56e16 kg
    Carme was the mother, by Zeus of Britomartis, a Cretan goddess.
    Discovered by Nicholson in 1938.
    Ananke, Carme, Pasiphae and Sinope are especially unusual in that their orbits are retrograde.
    Pasiphae
    Jupiter VIII
    Pasiphae is the fifteenth of Jupiter's known satellites:
    orbit: 23,500,000 km from Jupiter
    diameter: 50 km
    mass: 1.91e17 kg
    Pasiphae was the wife of Minos and mother, by a white bull, of the Minotaur.
    Discovered by P. Melotte in 1908.
    Ananke, Carme, Pasiphae and Sinope have orbits highly inclined to Jupiter's equator (about 150 degrees).
    Sinope
    Jupiter IX
    Sinope is the outermost of Jupiter's known confirmed satellites:
    orbit: 23,700,000 km from Jupiter
    diameter: 36 km
    mass: 7.77e16 kg
    Sinope was a woman said to have been unsuccessfully courted by Zeus.
    Discovered by Nicholson in 1914.
    Ananke, Carme, Pasiphae and Sinope may be remnants of a single asteroid that was captured by Jupiter and broken up.
