Planets of the solar system.

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

Something beyond Neptune

Astronomers have discovered the 9th planet of the Solar system?

Giant in the Kuiper belt

Perhaps, the ideas of humans about the Solar system far from reality. Scientists from the University of California, Michael brown and Konstantin Batygin has published a paper in which it is proved that in the Solar system there is at least one full planet .

For the first time sensational work of scientists was published in The Astronomical Journal, later it was reported by reputable scientific journals Science and Nature.

As stated in the work, a new planet, still do not have own names, was found by mathematical analysis of perturbations that experience the body the so-called “Kuiper belt” — space on the outskirts of the Solar system.

According to the calculations of brown and batygina, the ninth planet orbit is at a distance of 20 orbits from Neptune. Revolution around the Sun, this object travels in 10 – 20 thousand years. Planet, according to the findings of researchers exceeds the Land mass 10 times. Continue reading

Solar system, its model and structure

The universe (cosmos) is a whole world around us, limitless in time and space and infinitely diverse in forms, which takes forever moving matter. The eternity of the Universe in part you can imagine on a clear night with billions of different size luminous shimmering dots in the sky, representing the distant worlds. Rays of light at a speed of 300 000 km/s from the most remote parts of the Universe reach the Earth about 10 billion years.

According to scientists, the universe resulting from Big Bang 17 billion years ago.

It consists of clusters of stars, planets, cosmic dust and other cosmic bodies. These bodies form a system of planets with satellites (for example. Solar system), galaxies, Metagalaxy (accumulation of galaxies).

Galaxy (postdegree. galaktikos – milk, milky, from the Greek gala – milk) — a vast stellar system that consists of many stars, star clusters and associations, gaseous and dust nebulae, as well as individual atoms and particles scattered in space. Continue reading
