Frequently asked questions about the Solar system
How many planets in our solar system?
Our solar system consists of nine planets and one star – the Sun. We list the planets in order of distance from the Sun is mercury. Venus. Earth. Mars. Jupiter. Saturn. Uranium. Neptune and Pluto. In order to remember which planet is farther from the Sun, and what is closer to him (the order of the planets) often use the English mnemonic: M y V ery E ducated M other J ust S erved U s N ine P izzas. If You have Russian analogue of such a mnemonic, then we are happy to publish it, putting in the authorship.
3. What is the shape of the Solar system?
The planets, asteroids and comets in the Solar System are loose particles left over from the formation of the Sun. Originally the gas and dust which would become the Sun was the core of a cloud much larger than the Solar System, probably several light years across; where 1 light year is equal to approximately 10,000,000,000,000 kilometers (or 6 trillion miles).

At the Institute of biomedical problems started the experiment on simulation of a manned flight to Mars in the framework of the international project “Mars-500”.
The participants, six people will spend 105 days in a special complex, which will simulate a space ship. The experiment will include studies associated with the study of the proteome – the set and of the functioning of the human proteins. In particular, scientists will study the effects of extreme conditions on proteins.
Categories and tags: Tech “Science” Experiment. Flight. Mars. The Mars 500 Cosmonauts.
In the experiment “Mars-500” does not play study on the effect of factors such as weightlessness and increased radiation levels.
Scientists will study the effect of prolonged hypokinesia on the mineralization of bone. For this purpose the camera will be used in the peripheral scanner. Participants also will experience a special garment, created with the use of nanotechnology. Continue reading
The period of rotation around the Sun
Of 11.86 earth years
The first “date” earthly messenger with the giant of the Solar system – Jupiter was held in late 1973. Still on approach to Jupiter by “pioneer 10”, began to transmit color images of the planet Earth. On the screens in the mission control Center dynamic unfolding panorama of the approaching giant striped. Bright stripes on Jupiter are like ridges over high and cold clouds. And Vice versa: the dark stripes are the valleys between the ridges. Among the atmospheric lanes of the South tropical zone “blazed” the bright colors of the famous Great Red Spot.
Further large-scale image of this amazing education received by “Voyager-1” (the highest resolution on the images was 5 km), allowed us to understand the complex meteorology of Jupiter. It turned out that the mysterious spot has a clearly visible vortex structure: this is a floating disturbance in the atmosphere, in other words, a huge atmospheric vortex. In the spot, there is a rise of the substance and spreading it from the center. Continue reading
