the size and composition of the four outer Jovian planets (Jupiter, Saturn, Uranus, and Neptune) radically differ from those of the four terrestrial planets, which are closest to the Sun (Mercury, Venus, Earth, and Mars). Whereas the inner planets...
Mapping the distribution and extent of major terrain types on a planet's surface helps to constrain the origin and evolution of its crust. Together, MESSENGER and Mariner 10 observations of Mercury now provide a near-global look at the p... BW Denevi,MS Robinson,SC Solomon,... - 《Scienc...
Thermal history of Mercury's interior is examined using the model of Stevenson et al. (1983), extended to include the effects of tidal heating in Mercury's solid inner core. The implications of Mercury's thermal history for the source of the planet's magnetic field are discussed. It is sh...
However, the size and composition of the four outer Jovian planets (Jupiter, Saturn, Uranus, and Neptune) radically differ from those of the four terrestrial planets, which are closest to the Sun (Mercury, Venus, Earth, and Mars). Whereas the inner planets are composed mainly of heavier ...
The theory allows the motions of the Moon and planets to be calculated from first principles. Most planetary orbits are shown to be almost circular apart from that of Mercury, which is strongly elliptical. Newton also confirmed that the planets affect each other's paths as they orbit the Sun...
This chapter reviews the interior structure, chemistry, and dynamics of terrestrial planetary bodies: Mercury, Moon, Venus, Mars, and Io. There are many processes that connect these aspects of planetary interiors, the most important of which are discussed here. Fundamentally, the dynamics of terrest...
The gravitational tug of the planet on the parent star revealed its orbit to be extremely close (one-seventh of the distance from Mercury to the Sun) and swift (a ‘year’ in just four Earth days). Nearly 4,000 exoplanets have since been found. Image: NASA/ESA/G. Bacon (STScI)....
This chapter reviews the interior structure, chemistry, and dynamics of terrestrial planetary bodies: Mercury, the Moon, Venus, Mars, and Io. There are many processes that connect these aspects of planetary interiors, leading to the diversity of planetary surfaces and histories that we observe. ...
On May 5, 1961, NASA launched their first man into space, Alan Shepard, and continued the Mercury program for two years. However, just 20 days later, on May 25, President John Kenney challenged congress to establish the goal of sending a person to the moon and back by the end of the...
