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

Inside the comet 67P found no major voids

Interested in everything connected with high technologies.

Inside the comet 67P/Churyumov — Gerasimenko there are no large voids. The mission of “Rosetta” the European space Agency made measurements that clearly demonstrated and solved the old mystery. Comets are icy debris left over from the formation of the planets 4.6 billion years ago. Spacecraft have visited a total of eight comets, and through these missions we pulled a picture of the basic properties of these space-time capsules. On some questions the answers were found, others appeared.

Comets, as we know, consist of a mixture of ice and dust, and if there were compact, gravity superior to water. However, previous measurements have shown that some of them have very low density, much lower than water ice. Low density means that the comet must be extremely porous.

But what is this porosity: due to large voids in the subsurface of the comet, or due to a more homogeneous structure with low density? Continue reading

Galactic tourists

100 kilometers above the Earth’s surface (according to the international standards space begins at this altitude), speed – kmh 4000, which is 4 times the speed of sound, so it looks like a tourist flight into space, which you could see in sci-Fi movies or dreamed about since childhood.

Now the dream to see the immensity of outer space has already become a reality.

Who are those 5 people who first saw the Galaxy, read the article. We will also talk about the details of the flight and to quote the impressions of space explorers.
