The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .
Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.
Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.
The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available.
Outside the Solar system,on the contrary, or due to the large number of large heavenly bodies, or because of the excess water formed a huge body, surrounded by natural satellites. Continue reading
The planet Mars is one of the brightest objects in our night sky, even visible to the naked eye and resembles a bright red star. About every two years, our planet and Mars is a maximum converging. Such an event in astronomy is called “confrontation”. At this point, Mars will be only fifty-five millions of miles from Earth. People capitalize on that by sending to the Red Planet during the confrontation spaceships. So how much to fly to Mars ?
The orbit of Mars and Earth
The complete journey from Earth to Mars takes between 150 to 300 days to allow for the speed run, the location of the planets and the length of the path, which must pass the spacecraft. In this case the dominant factor is only the amount of fuel. The more fuel, the faster it will take flight.
History of flights to Mars
The first ever space ship, committed trip Earth-Mars, was created by NASA’s Mariner 4. It was launched in late November 1964 and appeared on Mars July 14, 1965. Mariner 4 reached Mars in 228 days. Continue reading
Length of day:

Jupiter is the fifth planet from the Sun and the largest planet in the Solar system. The surface of Jupiter are not made of stone, in contrast to the terrestrial planets closer to the Sun. The planet Jupiter is a huge ball of gas the size. Composition of atmosphere: hydrogen(85%), methane, ammonia, helium(14%). The composition of the atmosphere gas giant similar to the Sun. Jupiter radiates into space more heat than it receives from the Sun. The origin of this energy processes occurring in the core of the planet with hydrogen under huge pressure at which the gas acquires properties similar to metal.
Jupiter rotates so quickly that the planet is elongated along the equator. This intense rotation is the cause of hurricanes on the surface of the atmosphere where the clouds look like long stripes of different colors, rotating along the equator of the planet, often in opposite directions.
