I must say that the problem of space distances increasingly asserting itself. Chemical rockets on its effectiveness has exhausted itself for the future. Even the nearest planets of the Solar system on them to fly extremely long. Nuclear space engines while not in orbit, but on paper. Ion on a large scale. The spacecraft with solar sails will be valid only within the Solar system.
What engine to fly to the stars and how? After all, even with a nuclear engine will take flight for decades and centuries! Why? Because, according to theories, it is impossible to exceed the speed of light. And by estimations of astronomers, the nearest star to Earth with exoplanets (a planet similar to earth) is at a distance of 13 light years.
It is about exoplanet Kapteyn b, which is presumably suitable for life. For those who do not know: for light year, the astronomers believe the distance that a beam of light passes in our earth year at the speed of 300,000 kilometers per second. Other discovered exoplanets: Gliese 832c (16 light years), Gliese 667 Cc (22,7 light years), Kepler 186f (500 light years), Kepler 62f (1200 light years). But on a normal ship flight to the nearest star to us (alpha and Proxima Centauri – the distance in four and a half light years) will take time-75 thousand years. Of course, not light, but ordinary, earthly years. Continue reading
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).

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
