Earth Solar System

The Earth Solar System consists of the Sun, eight planets, their moons, and other celestial objects. Earth is the third planet from the Sun and is the only known planet to support life. The Earth Solar System is located in the Milky Way galaxy and plays a crucial role in sustaining life on our planet.

    ...The following sections are presented with that thought in mind. CONCEPTS TO SUPPORT KEY STAGES 1 AND 2 The solar system The Earth is one of eight planets that orbit the Sun. The Sun is a star – a burning ball of gas – that emits light and heat energy as deuterium (heavy hydrogen) atoms fuse to form helium atoms (see Key Idea 4.1 : Nuclear fusion). The planets do not emit light of their own and can be seen because they reflect the light of the Sun from their surfaces. A useful mnemonic for remembering the names of the planets, from the innermost (nearest to the Sun) outwards, is: M y V ery E nergetic M other J ust S erved U s N oodles TEACHING IDEA Children can create their own model solar system using fruit. There may not be a fruit big enough to represent the sun, and so you may have to use a ball.

Pluto is, therefore, considered a dwarf planet. The Sun contains more than 99 per cent of all the matter in the solar system, and it is the mass of the Sun that provides the gravitational force that keeps the planets in their orbits...

    ...Global warming has been changing the dynamics of the entire global system. Glaciers are melting at unprecedented rates, reducing our water stores, raising sea levels, and changing global oceanic water currents. As a result, these changes can affect weather patterns, storm activity and intensity, such as hurricanes, and global air temperature patterns. Unpredictable extremes in temperatures can occur, where one location may be much hotter than usual, while another is much colder than normal. Some locations may get more flooding, while others endure long droughts. Key Idea 5.6 Earth, Moon, and Solar System Since early in the history of humankind, people have watched the Sun, Moon, and stars. They described and named constellations. They used these objects for the development of cultural mythologies and for the construction of calendars and clocks. Although some of their understandings were naïve—such as the Earth being at the center of the universe—other understandings were incredibly accurate. These understandings led to systematized agricultural practices, the first calendars and sundials, navigational practices and devices, and a wide variety of cultural practices and mythologies. The Sun as Seen from Earth In this and other sections, we have seen how important the Sun is to life and to many of the physical processes on Earth. As seen in Figure 5.10, the relationship between the Earth’s rotational angle and the Sun is critical to understanding the seasons. From our position on Earth, the Sun’s daily “path” across the sky changes throughout the year. Although the Sun does spin on its axis and the whole solar system is moving along with the rest of our galaxy, it does not move around the Earth. Its apparent movement across the sky is due to the spinning of the Earth. The change in the Sun’s apparent path is due to the Earth’s orbit around the Sun...

    The Theory Of Celestial Influence

    Man, The Universe, and Cosmic Mystery

    ...III—THE SOLAR SYSTEM I—THE LONG BODY OF THE SOLAR SYSTEM A CONCEIVED BY MAN, THE SOLAR SYSTEM CONSISTS OF A GREAT radiant sphere, round which lie at harmonically increasing intervals, like the ripples round a stone-splash, the orbits through which revolve other smaller and non-radiant spheres. Like the stone in the stone-splash, this central radiant sphere or sun appears the source of the energy by which the whole phenomenon is created. With a diameter perhaps one-ten-thousandth that of its entire system, it stands in almost exactly the same relation to its vast field of influence as does a human ovum to the body which will grow from it. And since in both cases the smaller gives rise to the larger, the concentration or intensity of energy must be of a similar order. The concentric orbits of the dependent spheres or planets are harmonically related according to a law named after Bode. Taking the geometrical development 0, 3, 6, 12, 24, 48, 96, 192 and adding 4 to each figure, we arrive at a series which more or less represents the relative distances of the planetary orbits from the Sun. The planets themselves vary in size—in general increasing from the smallest, Mercury, which is nearest the centre, to the largest, Jupiter, midway between centre and circumference, and then again diminishing to the outermost known planet (Pluto), which is little larger than Mercury. The more remote the planets, the slower their apparent speeds, which diminish from Mercury’s 30 miles a second to Neptune’s 3⅓. This again is a characteristic of the dwindling of impulses sent out from a central source as it plunges ever more deeply into distance...

    The Planets & the Zodiac Signs

    ...Now that we no longer look upwards or watch the planets moving through the night skies we have lost our instinctive connection to these living gods and collectively we have ceased to take astrology seriously. It is sometimes said that the planets have stopped speaking to us because we have stopped listening to them, but if you have ever been in a place far from anywhere and looked up at the night sky, you will have experienced something of the majesty and power of the stars and planets. If there is any spark of imagination left in us, as we stand beneath the stars, trusting the emotions and intuitions that rise up in us, we can feel with bodily certainty that these birds of fire have an impact on human life, an influence that is undeniable. 1 As students of astrology, one of our first tasks is to get to know and understand the very basic astronomy and mechanics of the solar system. This is the foundation of our art and of our craft and if you can learn this now, it will stand you in good stead throughout your astrological studies. So let’s look at the order of the planets from the Sun. The anatomy of our solar system is not necessarily well understood. But it is extremely important for us, as astrologers, to know, not only because an understanding of the orbit periods of the planets and of their relative speeds is crucial when we come to study the planetary cycles and forecasting techniques, but also because the physical characteristics of the planets tell us a great deal about their astrological meaning. So we see from the following diagram that the orbital periods of the planets depends on their distance from the Sun. The first planet out from the Sun is Mercury, which moves very quickly, with an orbital period of only 88 days. Most of the time Mercury is obscured from view since it is either in front of or behind the Sun. When we do see it, it is only for a brief period as it darts round the outside of the Sun, now one side, now the other...
