Comets of the Solar system

Comets: the oldest inhabitants of the Solar system

J. L. Lagrange (1813) was also based on firmly established facts – the presence of comets that definitely move in elliptical orbits, including short-period. He explained the origin of comets gigantic volcanic explosions – emissions (eruption) with giant planets. It is, in principle, could explain the nature of the orbits of short-period comets. Subsequently, the views of La Grange shared and developed a number of scientists, among which the most important contribution of the Soviet astronomer S. K. Bo, who worked in this direction with the 20-ies to 80-ies of our century. He has eliminated the biggest internal difficulty is the concept of Lagrange – the necessity of the ejection of cometary masses (nuclei) with the “surface” of the giant planets with their powerful gravity fields, the overcoming of which requires an initial speed of 60 km/s and more. Giant planets also have thick (the length of many thousands of miles) and very dense atmosphere, in the middle of the twentieth century has been very problematic the very existence of a solid surface planets – giants beneath these atmospheres.

The largest planet of the Universe

Our universe is huge, and it seems to us that more of the globe there can be nothing, but it is not. There are planets much larger and more massive. For the whole of the Universe our Earth is just a grain of sand lost in her. The solar system is only one element of the Galaxy. The sun is the main component of the Galaxy. Eight planets revolve around the Sun. And only ninth – Pluto – due to its gravitational forces and the mass deduced from the list of rotating planets. Each planet has its own parameters, density, temperature. There are those that are composed of gas, there are giant, small, hot, cold, dwarf.

So what is the biggest planet known at the moment? In the spring of 2006 an event occurred that shook the theory about the heavenly bodies. In Rovellasca Observatory (USA, Arizona) in the constellation of Hercules was discovered a huge planet beyond our Earth twenty times. Existing outdoor today it is the largest planet in the Universe. She’s hot and like the Sun, but it’s still a planet. It was called TrES–4. Continue reading

Solar system

The science of studying celestial bodies and the Universe, astronomy . is one of the most important, since the beginning of time and reveals the secrets of our planet, Solar system and the Universe. The solar system consists of the Sun and many other celestial bodies that revolve around the Sun. It is located in Orion, one of the outer arm of the milky Way galaxy . the sleeves of these zones, which are characterized by a low density of matter.

What is in our Solar system?

In our solar system, you can find the planets mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune, and their satellites.

In the beginning, people thought that our planet Earth is in the center of the Universe, and the Sun, the stars revolve around the Earth. Copernicus, born in 1473, was the first person who proved that the Earth together with other planets of our solar system revolve around the Sun. Continue reading
