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.

“It’s huge”

About the discovery of the ninth planet of the Solar system two astronomers from the California Institute of technology in Pasadena became known on January 20. One of them — the native of Russia Konstantin Batygin — spoke about the search for Planet X, the difficulties with the title the new heavenly bodies and unsolved mysteries of the Solar system.

What is an open planet?

Konstantin Batygin . She falls into the category of dwarf planets. This celestial body is quite massive. Our model gives a mass of about ten earth, this planet is just a giant. Now it is defined as a celestial object whose gravitational field is dominant in that part of the Solar system.

In General, there is not even a question: it’s a planet or not. We know about it, because its gravity affects the orbit of the farthest objects in the Kuiper belt. The very mathematical modeling relies on the fact that this planet has enough mass for gravity to dominate in the Solar system. Continue reading

Small bodies of the Solar system


The rule of titzius-Bode r=0.3*2n+ 0,4 (.e)In the XIII century, astronomers searched for a planet whose orbit is held in the space between Mars and Jupiter In the beginning of the XIX century Italian astronomer Piazzi discovered the first minor planet (asteroid) Ceres.Opened the asteroid belt between the orbits of Mars and Jupiter

The movement of asteroids

The asteroids move around the Sun in the same direction as that of large planitia orbits have large excentricitate of them are removed at aphelion the orbit of Saturn, and perihelion closer to the Earth Mars and Hermes in 1937 passed from Earth to 580 000 km Icarus every 19 years closer to the Ground (2007)

There are about 300 thousand
