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

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.

Solar system – 8 planets and over 63 of the satellite, which are opened more often, several dozen comets and many asteroids. All cosmic bodies move in their precise directional trajectories around the Sun, which is 1000 times harder than any body in the solar system combined. The center of the solar system is the Sun – the star around which orbits the turning of the planet. They do not emit heat and not light, but only reflect the light of the Sun. In the solar system now officially recognized as the 8 planets. Briefly, in order of distance from the sun, we list them all. And now a few definitions.
A planet is a celestial body that must satisfy four conditions:
1. the body must revolve around the star (for example, around the Sun);
2. the body must have sufficient gravity to have a spherical or similar shape;
3. the body should not be near its orbit of other large bodies; Continue reading
