The methodology of extra-curricular activities
“History of cosmonautics”
Goal . formation of knowledge about the history of space exploration.
Secondary . formation of concepts:
– theoretical and practical assumptions kosmonavtiki research;
– the relation of the space with natural-mathematical Sciences and engineering;
– on the practical application of means of space exploration in science, technology, culture, industry and agriculture;
– about the space: space craft (SPACECRAFT), launch vehicles (LV), artificial Earth satellites (AES); spacecraft (SC), orbital stations (OS), automatic interplanetary stations (AWS);
– about the history of space research in Russia and abroad.
Educational . formation of scientific Outlook of pupils in the course of exploring the history of human knowledge. Patriotic education while getting acquainted with the outstanding role of Russian science and technology in space development. Polytechnic education and labour upbringing in presenting information on the practical application of space exploration. Continue reading
In addition, comets can carry the names of the people who discovered them, e.g., comet Halley, comet Machholz, comet shoemaker–levy 9 comet or Mac Note.
Movement and spatial distribution
All comets are members of the Solar system. They, like the planets, are subject to the laws of gravity, but move very peculiar. All the planets revolve around the Sun in one direction (which is referred to as “direct” as opposed to “reverse”) on nearly circular orbits that lie roughly in one plane (the Ecliptic), while comets move in both forward and reverse directions on highly elongated (eccentric) orbits, inclined at different angles to the Ecliptic. It is the nature of motion immediately gives the comet.
Long-period comets (orbital period greater than 200 years) come from regions located thousands of times further than the most remote planets, and their orbits are tilted at all angles. Short-period comets (period less than 200 years) come from the region of the outer planets, moving in the forward direction for orbits lying close to the Ecliptic. Continue reading
Solar system is a system of planets orbiting around a star, the Sun. Among those planets is our Earth. The solar System consists of the sun and of celestial bodies held by solar gravity. The mass of the sun is about 330 000 times the mass of the earth and makes up 99.8% mass entire solar system. The diameter of the sun is 1 400 000 km, i.e. about 109 Earth diameters. In the solar system except the sun is made up of eight planets, over 150 moons, and small bodies such as asteroids, comets and meteors.
In order of proximity to the Sun, the eight planets are mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
To measure distances in the solar system is used “astronomical unit” (AU). One AU corresponds to the distance from the earth to the Sun. Thus, the distance of one AU is nearly 150 million kilometers. For example, Jupiter rotates on its orbit 5.2 AU, i.e. the distance from the Sun is 5.2 times larger than the Earth. Continue reading
