Preliminary analyses of Doppler data from Pioneer 10 during its encounter with Jupiter indicate that the mass of Io is about 20 percent greater than previously thought and that Io's mean density is about 3.5 grams per cubic centimeter. A determination of the dynamical flattening of Jupiter (a - b)/a (where a is the semimajor axis and b is the semiminor axis) is found to lie in the neighborhood of 0.065, which agrees with the value determined from satellite perturbations. 

Pioneer 11 Infrared Radiometer Experiment: The Global Heat Balance of Jupiter

Data obtained by the infrared radiometers on the Pioneer 10 and Pioneer 11 spacecraft, over a large range of emission angles, have indicated an effective temperature for Jupiter of 125� � 3�K. The

Using early data to illuminate the Pioneer anomaly

Analysis of the radio tracking data from the Pioneer 10/11 spacecraft at distances between about 20–70 AU from the Sun has consistently indicated the presence of an unmodelled, small, constant,

The Galilean Satellites of Jupiter: Four Worlds

A broad survey is presented of our current knowledge of the Galilean satellites. Attention is given to the physical properties (size, masses, densities, and rotation) and to the surface properties

Radio Science at Jupiter: Past Investigations, Current Results, and Future Prospects

Over the last 40 years, several missions of the National Aeronautics and Space Administration (NASA) and European Space Agency (ESA) have explored the largest planet in the solar system, Jupiter.

Jupiter: Its Infrared Spectrum from 16 to 40 Micrometers

Spectral measurements of the thermal radiation from Jupiter in the band from 16 to 40 micrometers are analyzed under the assumption that pressure-broadened molecular hydrogen transitions are

The origin of the solar system: Implications for transneptunian planets and the nature of the long-period comets

If the solar system origin is considered within the framework of the author's hypothesis on the binary stars formation as a result of rotational-exchange break-up of the rotating protostar, then

Jupiter after Pioneer: a progress report

“We now come to a much more magnificent planet, Jupiter, the largest of them all …” So wrote Sir John Herschel in A Treatise on Astronomy1. Now, after a decade in which space programmes have

Physical properties of the natural satellites

This paper reviews the physical nature of the satellites of the planets, excluding the Moon but including the rings of Saturn. Emphasis is placed on the best studied objects: Titan, Phobos and

A history of the exploration of Io

On the 7th day of January in the present year, 1610, in the first hour of the following night, when I was viewing the constellations of the heavens through a telescope, the planet Jupiter presented
