Somehow it happened that I visited Kaluga in sufficient regularity, usually either passing through some of the local estate. or just cases.
Never got to walk around the city, and even more so to see the State Museum of the history of cosmonautics named after K. E. Tsiolkovsky. But once again it so happened that I had to go to Kaluga for one printing, meaning we had to ride 100 miles for 5 minutes. In the end, as in Kaluga, I got the idea to finally carry out his wish.
The state Museum of the history of cosmonautics named after K. E. Tsiolkovsky in Kaluga — the world’s first and Russia’s largest space Museum. In its creation participated personally famous designer Korolev and Yuri Gagarin. Last June 13, 1961 laid the first stone in the Foundation of the future Museum:
And after 6 years, the new Museum welcomed its first visitors. In the Museum you can get acquainted with the domestic history of cosmonautics, from the first artificial satellite of the Earth to modern long-term orbital stations. However, many of the original machines that had been in space you can see with your own eyes. 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
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
