Scientific enlightenment:

The planets in the solar system, from near to far from the sun, are mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. On the afternoon of August 24, 2006, at the 26th international astronomical union (iau), astronomers voted to officially classify Pluto as a dwarf planet. [1] most of the eight planets also rotate in the same direction as their revolutions. The only exceptions are Venus and Uranus. Venus rotates in the opposite direction of its revolution. Uranus is in orbit. Pluto, once known as the \"nine planets,\" was defined as a \"dwarf planet\" on August 24, 2006.

Experimental purpose:
1. What are the eight planets?
2. What are the characteristics of the eight planets?

Principle application:

In order of distance from the sun, the planets are mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus and Neptune. Mercury, Venus, earth and Mars are called earth-like planets, while Jupiter, Saturn, Uranus and Neptune are called wood-like planets. The wood-like planets are surrounded by rings of dust and many small particles, and with the exception of the earth, visible planets are named after the five elements, and in the west all are named after the gods of Greek and Roman mythology.

Experimental cognition:

We often compare the solar system to a large and harmonious family, of which the sun is the supreme \"head\". Its strength and power keep all the members of the family on the right track around it. In this solar family, the eight planets are the children of the sun, and dozens of moons are its grandchildren...
The planets themselves do not give off light, but as they are near the sun, close to the earth, they are all very bright and dazzling, and only these bright stars wander \"without rules\" in the sky. They come and go, fast and slow, unpredictable, and hence the name \"planet\". The west calls it \"Planet\", which means \"wanderer\". The driving force behind the development of ancient astronomy, so to speak, was to explain and predict the positions of the planets.
Solar system refers to the system composed of the sun and the celestial bodies moving around it and the space occupied by it. Broadly, the realm of the solar system includes the sun, four inner planets like earth, an asteroid belt made up of many small rocks, four giant outer planets filled with gas, and a second small body called the kuiper belt filled with small frozen rocks. Beyond the kuiper belt are the ecliptic discrete disk, the heliosphere, and the still-hypothetical oort cloud.

Knowledge development: learn about horoscopes

The constellations are an essential part of astrology and are also the clusters of stars in the sky. Since ancient times, humans have associated small groups of stars with their mythological characters or instruments, known as \"constellations.\" In 1930, the international astronomical union (iau) used the boundary, based on ancient Greek mythology handed down from the middle ages, to divide the sky into eighty-eight official constellations. These constellations are widely used in navigation and are the means by which almost all civilizations locate their position in the sky.

Origin of constellations
In order to facilitate the study and observation of many stars in the sky, the astrologers of the mesopotamian civilization divided the sky into several regions, each region being a constellation. It's hard to say exactly when humans first had the concept of constellations, and this kind of astronomical knowledge was understood long before recorded history. The names of the constellations probably came from early sailors. The origin of the constellations may be completely different in different civilizations, but as the civilizations expand and influence each other, the cultures of the constellations also involve the process of fusion.

Knowledge extension:

The original babylonians made a horoscope calendar of the seasons according to the movement of the stars, hoping to use it to divine and predict the fate of their people. In fact, this method of divination is similar to the number of purple and wei dou in ancient China. It is based on the relationship between the diviner and the movement of the stars, accounting for all aspects of his life. Because the ancient people in accordance with the changes of the sky to survive, the natural disaster is irresistible, thus resulting in the human sense of fate; And they found that the movement of the sun, moon and stars in the universe affects the rise and fall of all things, even the fate of people.

At the time of birth, each planet in the solar system, large or small, including the sun, moon, Venus, Jupiter, mercury, Mars, Saturn, Neptune, Uranus and Pluto, moves at different angles and distances and therefore has a significant impact; Each planet and its corresponding 12 signs cause and effect each other, and each has a different effect on the personality part of the person. For the horoscope should be in a scientific attitude, believe rather than superstitious, see \"dong shiming on the status and development of fortune telling fengshui culture\".

The sun sign is often mentioned in horoscopes, as long as you know a person's date of birth, you can find out which sun sign he belongs to. The orbit of the sun is called the ecliptic, and the ecliptic is divided into 12 regions, each of which is 30 degrees. The twelve signs are divided into the beginning of spring, that is, the sun in the annual March 20 around the vernal equinox began to order, is: Aries, Taurus, Gemini, cancer, Leo, virgo, libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces. Each person only belongs to one sun sign, because the time of the sun enters the house is different each year, if the birthday is in the constellation boundary, it is necessary to look up the astronomical calendar to judge its sun sign, will not appear across the two sun signs. Astrology holds that the sun signs represent innate personality, willpower, and ways of self-expression. Through sun signs we can have basic knowledge about a person, but to fully understand a person, in addition to the sun sign, but also the fall of the house, and to see the sun and other stars, even if the sun sign, is located in the palace and Angle is different, affected by the sun sign is different also, so personality not only twelve kinds of classification.
