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
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
Among all the planets of the Solar system Jupiter occupies a special position. First, it is the largest planet in our Solar system. Secondly, it is the planet having the largest number of satellites (currently known 67). Thirdly, it is not just the heaviest planet in the Solar system, and planet, the mass of which in 2.47 times the mass of all other planets combined. Ganymede, one of Jupiter’s moons, is the largest natural satellite in the Solar system. In addition, the popularity of the planet gives a local landmark – the Great red spot (BKP), which is a mysterious storm, continuing on Jupiter for hundreds of years.
It should be noted that most of the news concerning Jupiter, deals either with his companions or with BCP. It’s safe to say that much more interest for scientists is the study of the satellites it than him. Of particular interest are the moons IO and Europe . IO has a huge number of active volcanoes, for which this satellite was the status of the most geologically active satellite in the Solar system. And the ice surface of Europa conceals a liquid ocean, which literally forces scientists to look for life on this satellite. In this category of our website you southeastasia with the latest news concerning Jupiter’s moons and, of course, himself. Continue reading
