Solar system

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:

1. Planet

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

Brown and Batygin told about the discovery of the ninth planet of the Solar system

Scientists shared their impressions

21 January 2016, two scientists from the California Institute of technology, Professor Mike brown and Professor Konstantin Batygin has officially announced that they have found a ninth planet in our Solar system. According to their mathematical models, it is a gas giant like Uranus or Neptune, the mass of the discovered planet 10 times the mass of Earth, it rotates in an orbit 20 times larger than the earth and it requires from 10,000 to 20,000 years to make one complete revolution around the Sun. However, very reliable model of scientists has demonstrated and existing telescopes have not yet managed to see her.

Scientists have been very mixed on the nature of their activities and perhaps that is why they have achieved such amazing results. So brown has increasingly resorted to methods of observation and explores distant objects in our Solar system, whereas Batygin relies more on the laws of physics and mathematical calculations. Apparently, that tandem allowed the researchers to calculate the so-called ninth planet. Continue reading

The most important mysteries of the solar system

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
