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 the planetary system that includes the Sun. and all the objects orbiting it – planets, moons, asteroids. comet. a large number of meteoroids, gas and cosmic dust .
But how was Solar system formed? The universe formed through the Big Bang. There is the Big Bang theory, which says that long ago the universe was small and hot lump. Suddenly it exploded, expanded space, the temperature of the particles decreased considerably. Due to the force of gravity began to gather clouds of matter, the result of which was formed all the galaxies and stars. It took about 8 billion years after the Big Bang, before the Solar system was formed. The matter is unevenly distributed in space and began to attract the dust and gas. Formed dust and gas clouds, they eventually formed star, the Sun. From other particles of the cloud formed other objects.
Components of the Solar system are divided into categories:
3. Small body
The center of the Solar system is the Sun . It accounts for almost all of the bulk system – 99,87 %. Continue reading
