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).

Started the experiment to simulate a flight to Mars

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.

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 Solar system

In space you can find a lot of quaint places with abnormal high or low temperature. Or meet the largest meteorite, asteroid, the massive comet, the highest mountain, the Grand canyon and much more. On space records in the Solar system in this article and will be discussed.

Planet with maximum surface temperature

The highest temperature that was recorded on Solar system planets — 464 °C on the planet Venus . Due to the very thick atmosphere it holds heat from the sun and at night the temperature is almost constant day and night. Slightly lower was the recorded temperature on the planet mercury — 430 °C.

The lowest recorded temperature on the surface of the body

The largest planet

The largest planet in the Solar system — Jupiter . The diameter of our planet is almost 11 times, and the mass of the earth is approximately more than 317 times. It is a gas giant. which contains more matter than all other planets, their satellites, comets and asteroids combined. Continue reading
