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

The Planet Jupiter

Among all the planets of the Solar system Jupiter occupies a special position. First, it is the largest planet in our Solar system. Secondly, it is the planet having the largest number of satellites (currently known 67). Thirdly, it is not just the heaviest planet in the Solar system, and planet, the mass of which in 2.47 times the mass of all other planets combined. Ganymede, one of Jupiter’s moons, is the largest natural satellite in the Solar system. In addition, the popularity of the planet gives a local landmark – the Great red spot (BKP), which is a mysterious storm, continuing on Jupiter for hundreds of years.

It should be noted that most of the news concerning Jupiter, deals either with his companions or with BCP. It’s safe to say that much more interest for scientists is the study of the satellites it than him. Of particular interest are the moons IO and Europe . IO has a huge number of active volcanoes, for which this satellite was the status of the most geologically active satellite in the Solar system. And the ice surface of Europa conceals a liquid ocean, which literally forces scientists to look for life on this satellite. In this category of our website you southeastasia with the latest news concerning Jupiter’s moons and, of course, himself. Continue reading
