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
About the discovery of the ninth planet of the Solar system two astronomers from the California Institute of technology in Pasadena became known on January 20. One of them — the native of Russia Konstantin Batygin — spoke about the search for Planet X, the difficulties with the title the new heavenly bodies and unsolved mysteries of the Solar system.
What is an open planet?
Konstantin Batygin . She falls into the category of dwarf planets. This celestial body is quite massive. Our model gives a mass of about ten earth, this planet is just a giant. Now it is defined as a celestial object whose gravitational field is dominant in that part of the Solar system.
In General, there is not even a question: it’s a planet or not. We know about it, because its gravity affects the orbit of the farthest objects in the Kuiper belt. The very mathematical modeling relies on the fact that this planet has enough mass for gravity to dominate in the Solar system. Continue reading
