Solar system. Planets of the solar system
Its center is a huge star called the Sun. It is the closest star that is billions of years gives us light and heat. Without it, impossible would be life on the planet. Around it revolve the planets, of which eight are known today, as well as other celestial objects.
Schematically, the structure of the solar system is as follows:
Man is always interested in the question thus arose our solar system. But it was a long time before scientists were able to answer this question. There were many versions and assumptions on this issue. And today, astronomers are continuing their investigation.
According to a hypothesis of Kant-Laplace five billion years ago there was only a gas cloud. It moved through the universe, but at some point he undergoes certain processes. Then there is compression and then begins the rotation, the center of rotation is the fastest. The temperature at the center of the cloud began to grow and formed a protostar that later became the Sun. The nebula continued to spin, and the star are unable to absorb all the substance of the nebula, they are attracted, experienced, forming planetesimal. One of them appeared on the planet.

Unlikely in 1930, when the world learned of the existence of Pluto, someone could believe that someday people will be able to find there their last resting place. However, this can happen very soon. NASA space ship with the remains of Clyde Tombaugh, discoverer of Pluto, had almost reached the destination. The journey of the ship lasts for more than 9 years. Soon NASA promises to publish the first pictures from the distant dwarf planet, the study of which may help answer many questions about the origin of the entire Solar system.
kosmicheskiy the NASA New Horizons spacecraft has begun to explore Pluto. The aircraft approached the icy dwarf so much that this week the staff of the American space Agency promise to show him the first Pictures. The input apparatus into the atmosphere of the dwarf planet is scheduled for July 2015.
Note that the distance to Pluto is 30 times more than from the earth to the Sun, and the spacecraft New Horizons was launched back in early 2006. On his way the machine New Horizons flew past Jupiter and Saturn, in the literal sense, rebounding from their orbits, which gave the ship a significant acceleration. Up to this point most distant mission was considered an American Kosmicheskaya flight of Voyager, which in 1980 had reached Saturn. Continue reading
