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

10 huge space objects

Of course, the oceans are huge and mountains impress with their value. And seven billion people is a lot, but still. Since we all live on planet Earth (whose diameter is 12 742 km), it is easy to forget how insignificant we really are small. All we need to do is look up at night, the sky, and realize that we are just a bunch of dust in the immeasurable vast Universe.

10. Jupiter. The largest planet (142 984 kilometres in diameter)

Jupiter – the largest planet of our Solar System. Ancient astronomers named Jupiter after the main Roman God. Jupiter is the fifth most close planet to the Sun. The atmosphere of Jupiter consists of about 84 percent hydrogen and about 15 percent helium, with small amounts of acetylene, ammonia, ethane, methane, phosphine, hydrogen and water vapor. Jupiter has a mass 318 times the mass of Earth and a diameter 11 times larger than the diameter of the Earth. The mass of Jupiter is 70% of the total mass of all other planets of our Solar System. The volume of Jupiter is large enough that it could fit 1300 planets the size of Earth. The planet has 63 known satellites (moons) but most of them have very small sizes, and disappear.
