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

Unsolved mysteries of the Solar system

While the Solar system in General and Earth in particular is the only house people, we need to know about this house. And what? Humanity is grappling over the years, it would seem, not so complicated questions, and no answers.

1. The Oort Cloud. Does the Oort cloud

The Oort cloud is the biggest mystery of the Solar system. People have never seen this hypothetical plot of the Universe, which, according to theories, is a place of formation of the comets with a long period of treatment. Scientists believe that the Oort cloud is located at a distance from 50 thousand to 100 thousand. E. from our Sun. Its outer boundaries lie on the boundary of the Solar system, and billions of bodies out of the Oort cloud is gravitationally bound to the Sun.

2. The anomaly of the spacecraft “pioneer”. Why probes pioneer deviate from the course?

Space probes “pioneer 10” and “pioneer 11” were launched in 1972 and 1973, respectively, to study the outer limits of the Solar system. NASA scientists have observed significant deviations of vehicles from the course, due probably to the action of gravity of the Sun. When more detailed calculation of the acceleration of the spacecraft found a very weak force of unknown nature, which operated on them. Continue reading

Comets and asteroids

Us flies a terrible comet,

It sent the angered Creator.

We are powerless. Doomed planet.

Everyone died. Inevitable end.

In the obdurate depravity without measure

Meanwhile, talking to the peoples of the hypocrites:

We’ve had enough! Old our world.

And drink and eat and continue the feast.

Pierre-Jean Beranger

Made in the epigraph of this section of row P. J. Beranger has written more than two hundred years ago, when astronomy was in the beginning of the knowledge of the laws of the Universe and every cosmic phenomenon was perceived as a supernatural manifestation of higher powers beyond the human mind.
