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
The earth is the home of humankind. Can be considered and the Solar system. After all, we already went to the moon, our spacecraft has reached other planets. It would seem that about the area of Land we need to know everything.
Actually mankind for decades trying to unravel such close and such mysterious phenomena. Describe below of the top ten mysteries of the Solar system.
The Oort Cloud. The main issue regarding this site is that whether there is any? This is perhaps the chief mystery of our Solar system. Scientists have suggested the existence of clouds only hypothetically, but this piece of the Universe no one has seen. The theories then formed comets with long orbital period. Scientists can only assume that the Oort cloud is at a distance of 50-100 thousand.e. from the Sun. The bounds of this object lying on the very edge of the Solar system. The billions of bodies are from the cloud is bound by gravity to the Sun. Continue reading
The science of studying celestial bodies and the Universe, astronomy . is one of the most important, since the beginning of time and reveals the secrets of our planet, Solar system and the Universe. The solar system consists of the Sun and many other celestial bodies that revolve around the Sun. It is located in Orion, one of the outer arm of the milky Way galaxy . the sleeves of these zones, which are characterized by a low density of matter.
What is in our Solar system?
In our solar system, you can find the planets mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, and their satellites.
In the beginning, people thought that our planet Earth is in the center of the Universe, and the Sun, the stars revolve around the Earth. Copernicus, born in 1473, was the first person who proved that the Earth together with other planets of our solar system revolve around the Sun. Continue reading
