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. Continue reading

The SOLAR SYSTEM’s NINTH PLANET BATYGIN NEPTUNE NEW PLANET

Why Just the ninth planet in the Solar system, according to the International astronomical Union (IAU), there are eight planets. Pluto the IAU decision in 2006 is no longer considered a planet by going to the class of dwarf planets because it is not dominant in its space orbit. According to scientists, the Solar system may be over two thousand dwarf planets. However, the definition of a planet as a dwarf is still a matter of controversy. In particular, a crucial role may play the size of a celestial body.

Therefore, to say that discovered ninth planet in the Solar system very early.”

The scientist reminded that beyond the orbit of distant planets in the Solar system has many objects that are studied by astronomers. Among them was discovered a new heavenly body, which claims the title of planet in the Solar system.

According to the authors, it is a gas giant with a mass of 5-10 times the mass of the Earth. This planet supposedly moves in an elliptical orbit, making a complete revolution around the Sun for 10-20 thousand years. According to the calculations of astronomers to confirm the planet’s existence by observation through the telescope, will take several years. Continue reading

Discovered the largest known planets

The biggest of all open still planets astronomers found in the constellation of Hercules.

Space body, named TrES-4, is drawn around the star GSC02620-00648, remote from the Earth at a distance of 1435 light-years. A new extrasolar planet about 70% larger size than Jupiter, but has a much smaller mass, which indicates its extremely low density. In addition, the object is deleted only 7 million kilometers from its star, making its surface extremely hot, over 1300 degrees Celsius.

Around its star turns the planet every 3.55 days, you one earth week to two years, listed on TrES-4. Because of the relatively weak gravity TrES-4, probably permanently loses a part of the upper layer of its atmosphere, which stretches behind the planet in the form of a curved tail resembling a comet.

“This is the largest of all known exoplanets, says lead researcher George Mandushev from the Lowell Observatory. It is so large that using existing scientific models to superhot giant planets its size is quite difficult to describe. Continue reading
