Pluto Uranus

The planets in the solar system the largest planets are Jupiter, Saturn (shown with its characteristic rings), Neptune and Uranus. Pluto (shown at the top left of the illustration) has been reclassified as a dwarf planet.

Our solar system consists of the Sun, the planets and their moon satellites, asteroids (small planets), comets, and meteorites. The planets are generally divided into two categories Earth-like (terrestrial) planets—Mercury, Venus, Earth, and Mars and Giant planets—Jupiter, Saturn, Uranus, and Neptune. Little is known about Pluto, the most remote planet from Earth. 

The gas giant planets Jupiter, Saturn, Uranus and Neptune. The planet Pluto has a status of its own, and has recently been renamed a dwarf planet. 

The density estimates in Table 7.1 show a distinction between the structures of the planets, with Mercury, Venus, Earth and Mars all having mean densities consistent with a rocky internal structure. The Earth-like nature of their composition, orbital periods and distance from the Sun enable these to be classified as the terrestrial planets. Jupiter, Saturn and Uranus have very low densities and are simple gas giants, perhaps with a very small rocky core. Neptune and Pluto clearly contain more dense materials, perhaps a mixture of gas, rock and ice. 

Of some interest is that after uranium ( jU) was named after the planet Uranus, neptunium (jjNp), which was discovered next, was named after Neptune, the next planet in our solar system. And Anally, plutonium (g4Pu) the next transuranic element discovered, was named after Pluto, the last planet discovered so far in our solar system.

The chemical dynamics, reactivity, and stability of carbon-centered radicals play an important role in understanding the formation of polycyclic aromatic hydrocarbons (PAHs), their hydrogen-dehcient precursor molecules, and carbonaceous nanostructures from the bottom up in extreme environments. These range from high-temperature combustion flames (up to a few 1000 K) and chemical vapor deposition of diamonds to more exotic, extraterrestrial settings such as low-temperature (30-200 K), hydrocarbon-rich atmospheres of planets and their moons such as Jupiter, Saturn, Uranus, Neptune, Pluto, and Titan, as well as cold molecular clouds holding temperatures as low as 10...

Neptune s large satellite Triton, which has a very thin nitrogen atmosphere with clouds, plumes, and haze, an extremely cold surface with nitrogen, methane, carbon monoxide, and carbon dioxide ices which interact with the atmosphere, and a fairly high mean density, make it seem more like Pluto than the other satellites of Neptune and those of Saturn and Uranus. Not enough is known about Pluto to explore these similarities this probably awaits future missions to Pluto, especially the New Horizons mission that NASA hopes to launch in 2006. 

Neptune clockwise instead of counterclockwise (direct motion). If c ie views the solar system from above the Sun s north pole, all the planets have diiect (counterclockwise) revolutions around the Sun, and most of them have direct rotations the exceptions are Venus, Uranus, and possibly Pluto. Infrared (at wavelei lhs loi r than those of red light) observations of Triton since 1980 indicated the presence of an atmosphere containing methane, and the presence of nitrogjen in solid or liquid form on its surface. However, its size and mass remained poorly known. 

Solid N2, CH4, H2O, and CO have been found on Triton and Pluto, witli additional CO2 on Triton. The molecule N2 dominates both surfaces, and other molecules are trapped in an N2 matrix. The only molecule identified on Charon is H2O. Surface compositions of these two bodies are quite different from those of satellites of Jupiter, Saturn, and Uranus. The compositional relationsliip of Triton and Pluto to that of tlie Edgeworth-Kuiper belt objects, and to tlie comets, is still unclear. 

Seaborg s team suggested the name plutonium for the new element, in honor of the planet Pluto. The two elements just before plutonium in the periodic table had also been named for planets uranium for Uranus and neptunium for Neptune.

The solar system is sometimes divided into two parts consisting of the inner planets—Mercury, Venus, Earth, and Mars—and the outer planets—Jupiter, Saturn, Uranus, Neptune, and, until recently, Pluto. One might imagine that understanding the chemical and physical properties of the inner planets would help in understanding the chemical and physical properties of the outer planets. No such luck. The two groups of planets differ from each other in some fundamental and important ways. 

Researchers have learned a vast amount of new information about Jupiter, Saturn, Uranus, Neptune, Pluto and the Kuiper Belt Objects in the last century. Improved terrestrial telescopes, the Hubble Space Telescope, and space explorations such as Voyager 1 and 2, Galileo, and Cassini have produced new data that will take astrochemists years to analyze and interpret, providing them with even more detailed information about the chemical composition of the atmospheres, satellites, surfaces, and other features of the outer planets and their associated bodies. 

In the centre we see the other planets Saturn, Uranus, Neptune, and Pluto. Vegetalistas may visit all these planets rather easily, because they are not very far away. 

The chapters in this part help fill in those blanks. Chapter 8 illuminates the Moon and the Nodes of the Moon in all 12 signs. Chapters 9 and 10 discuss Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto — plus the asteroid Chiron, which was discovered in 1977 and is now routinely included in horoscopes by many astrologers. Chapter 11 talks about the Ascendant, and Chapter 12 describes the influence of the planets in each of the houses. Finally, Chapter 13 looks at the way the planets interact by analyzing the aspects, or geometrical relationships, that link them together. 

In Chapters 16, 17, and 18,1 tell you how to squeeze the maximum benefit out of astrology. Chapter 16 explains how the current positions of Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto affect you — and what you can look forward to in the future. 

The sign that the Sun occupied at the moment of your birth is the most basic astrological fact about you. It defines your ego, motivations, needs, and approach to life. But the Sun isn t the only planet that affects you. (For astrological purposes, both luminaries — the Sun and the Moon — are called planets. Do yourself a favor and don t use this terminology when talking to astronomers.) Mercury, Venus, Mars, Jupiter, Saturn, Chiron, Uranus, Neptune, and Pluto, not to mention the Moon, represent distinct types of energy that express themselves in the style of the sign they re in. 

After Uranus was discovered in 1781, followed by Neptune in 1846 and Pluto in 1930, astrologers modified the system. Today, the most commonly accepted planetary rulers are as follows ... 

Uranus is in Virgo. Neptune is in Scorpio. Pluto is in Virgo. 

In the next century, scientists realized that anomalies in the orbit of Uranus could be accounted for by the presence of another planet. In 1846, after a search marked by total confusion (in keeping with the nature of the planet), European astronomers identified that unknown body and named it Neptune A third discovery further expanded the solar system in 1930, when Clyde Tombaugh, a 23-year-old amateur who was hired to examine photographic plates of the night sky, found what he was looking for A tiny, distant body, which is now named Pluto. 

The outer planets are also harbingers of change, both external and internal. These planets shake you up (revolutionary Uranus), inspire and confuse you (nebulous Neptune), and push you to the brink (take-no-prisoners Pluto). They represent the invincible, unstoppable, cosmic forces of change. 

Uranus spends about seven years in each sign. Like Neptune and Pluto, it makes its greatest impact on generations. In an individual chart, its influence is subtle — most of the time. But when it s prominent in a birth chart, Uranus is the mark of geniuses, idealists, iconoclasts, nonconformists, eccentrics, inventors, revolutionaries, and astrologers. 

If you were born between 1962 and 1969, you have both rebellious Uranus and transformative Pluto in Virgo. Although the impracticality of much of what went down in the 1960s probably irritates you, on some level you re deeply in sync with the urge to break away from old forms, alterthe hidebound assumptions of mainstream society, and give peace a chance.
