Hello dear readers! In this post we will talk about the structure of the Solar system. I think you just need to know where in the Universe is our planet, and what else is in our Solar system besides planets.
Our planet Earth is part of the system of planets and other celestial bodies that rotate around a star called the Sun. The solar system is one of many such systems in the Universe .
The solar system is a system of cosmic bodies, which in addition to the Central luminary – the Sun, nine major planets, their satellites, the numerous small planets, comets, space dust and small meteoroids that move in the field pre-emption gravitational action of the Sun.
In the middle of the sixteenth century was uncovered the General structure of the Solar system Polish astronomer Nicholas Copernicus. He disproved the idea that the Earth is the center of the Universe and substantiate the presentation of the motion of planets around the Sun. This model of the Solar system was called the heliocentric. Continue reading
5 unknown facts from the life of Konstantin Eduardovich Tsiolkovsky
On September 19, 1935 in Kaluga passed away the great Russian inventor Konstantin Tsiolkovsky . Exactly one year later there was opened house-Museum of scientist-taught and a pioneer of cosmonautics, whose life with her careful study expands like the universe.
1. Opponent of Einstein, an admirer of Lenin
However, the Tsiolkovsky-the theory of expansion of the universe was denied, as he denied the theory of relativity . Konstantin Eduardovich did not agree with Einstein that the universe is limited in size to two hundred million light years. According to Tsiolkovsky, the claim is as absurd as to assert that in the cross section of the universe equals one millimeter. Continue reading
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
