THE SOLAR SYSTEM
PLANETARY DATA – JUPITER▼ The south-east quadrant
of Jupiter: 18 November
2001, seen from the Cassini
vehicle. The Great Red Spot,
to the right, is about to be
carried out of view by virtue
of Jupiter’s rotation.
Ganymede, the largest of
Jupiter’s moons, is visible at
bottom right. The image is a
colour composite, produced
by combining images taken
with different filters.Sidereal period 4332.59 days
Rotation period (equatorial) 9h 55m 21s
Mean orbital velocity 13.06 km/s (81 miles/s)
Orbital inclination 1° 18’ 15”.8
Orbital eccentricity 0.048
Apparent diameter max. 50”.1, min. 30”.4
Reciprocal mass, Sun = 1 1047.4
Density, water = 1 1.33
Mass, Earth = 1 317.89
Volume, Earth = 1 1318.7
Escape velocity 60.22 km/s (37.42 miles/s)
Surface gravity, Earth = 1 2.64
Mean surface temperature 150°C
Oblateness 0.06
Albedo 0.43

Diameter (equatorial) 143,884 km (89,424 miles)
Diameter (polar) 133,700 km (83,100 miles) Jupiter, as imaged from
the Cassini vehicle on 7
December 2000. At this time
the Great Red Spot was very
much in evidence; to the left
and below the Spot there is s
series of white ovals. The
black circle towards the left
is the shadow cast by Europa
on to the planet. This
photograph was generated
in a computer by combining
four separate images.EarthC Atl of Univ Phil'03stp 2/4/03 3:08 pm Page 95
