The origin of the solar system

The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .

Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.

Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.

The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available.

Outside the Solar system,on the contrary, or due to the large number of large heavenly bodies, or because of the excess water formed a huge body, surrounded by natural satellites. Continue reading

Flight to Mars

Modern physics. A flight to Mars.

Russia is technically ready to organize a manned mission to Mars in early 2020-ies, the Director of the space research Institute of Russian Academy of Sciences the academician the lion Green.

“Priority for Russia, and prestigious really the first to disembark an astronaut on Mars. This problem is economically and technically solved”, — said L. Green. According to him, if to begin preparations for flight in the near future, Russian cosmonauts can land on the surface of Mars in 2023-2025 years.

For the organization of the expedition, says L. Green, hurt Russia more than any other country, including the United States.

“We now have a certain handicap in this race, as we have the biggest experience in manned space exploration. Even in the bad 90’s, he worked as the station “Mir”, then there was the ISS. Thus a chain of manned flights have not been interrupted,” — said the scientist. Continue reading

Planets of the solar system.

Solar system – 8 planets and over 63 of the satellite, which are opened more often, several dozen comets and many asteroids. All cosmic bodies move in their precise directional trajectories around the Sun, which is 1000 times harder than any body in the solar system combined. The center of the solar system is the Sun – the star around which orbits the turning of the planet. They do not emit heat and not light, but only reflect the light of the Sun. In the solar system now officially recognized as the 8 planets. Briefly, in order of distance from the sun, we list them all. And now a few definitions.

A planet is a celestial body that must satisfy four conditions:

1. the body must revolve around the star (for example, around the Sun);

2. the body must have sufficient gravity to have a spherical or similar shape;

3. the body should not be near its orbit of other large bodies; Continue reading
