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 Solar System, the third brightest object night sky (after the moon and Venus). Is gazaille body, hard surface does not. Consists mostly of hydrogen and helium. Due to their size can be observed with the naked eye as a star of the first magnitude, but only for a short time in the morning or in the evening. The average distance from the Sun 778 million km conversion – 314.8 years 11 days.
Jupiter has 16 satellites: IO, Leda, Teba(Phoebe), Carme, ELARA, Ananke, Europe, Metis, Pasiphae, Sinope, hamalia, Ganymede, Lysithea, Amalthea, Callisto, and Andrastea. System his companions like a scaled-down model of the Solar system. The four major satellites (Ganymede, Callisto, IO and Europa) discovered by Galileo and are called the Galilean. Continue reading
The planets and moons in orbit of the Sun
The largest planet in the Solar system. this is a Jupiter belonging to the class of gas giants. Ancient astronomers were able to detect and assign a very unusual name this planet. Named in honor of one of the most revered Roman gods, Jupiter is not in vain was honored to be the namesake of the thunder gods. For large-scale weather events, continuously produced in the atmosphere of the giant, strength and scale can outdo the deeds of the most powerful gods! Imagine the worst stormy weather on our planet. And now imagine the same thing, but only 10 times more intense and more powerful. These horrific lightning strikes, as if the gods went crazy and wants to destroy everything. Wild, wild the storm that engulfs everything in its path, and sometimes of centuries.
Jupiter is not alone in its orbit, having 67 different dimensions of the satellites. Like any ordinary giant planet has attracted much attention of scientists. A lot of research spacecraft was sent to Jupiter during the long years of study. Periodically, during the great opposition, Jupiter looks like the brightest star in the heavens. In this period of time activates the monitoring planeteurodisco ground-based and orbiting telescopes. Continue reading
