Model of the Solar system

Solar system is a system of planets orbiting around a star, the Sun. Among those planets is our Earth. The solar System consists of the sun and of celestial bodies held by solar gravity. The mass of the sun is about 330 000 times the mass of the earth and makes up 99.8% mass entire solar system. The diameter of the sun is 1 400 000 km, i.e. about 109 Earth diameters. In the solar system except the sun is made up of eight planets, over 150 moons, and small bodies such as asteroids, comets and meteors.

In order of proximity to the Sun, the eight planets are mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

To measure distances in the solar system is used “astronomical unit” (AU). One AU corresponds to the distance from the earth to the Sun. Thus, the distance of one AU is nearly 150 million kilometers. For example, Jupiter rotates on its orbit 5.2 AU, i.e. the distance from the Sun is 5.2 times larger than the Earth. Continue reading

The principle of operation

Obviously, enough people settled on the planet. Now he rushes into space to other planets, other worlds. Me some time ago, suddenly puzzled question that, maybe, the desire to space as it is genetically built into the human population. Give this thought to those who insist on the theory of extraterrestrial origin of life. Perhaps this is an argument in the dispute. Life originated in space and was for the planet entered, so man tends back. The truth is, other living creatures, tearing at the limits of Earthly comfort I do not know.

One way or another, but wanting to hit the road for a week not in Komarovo, and the ISS, among the millionaires abound. It is a pity that the station still more and to carry back only the tourists are not going. Today for money on the ISS managed to get only five people. The other fly to work. This is a troublesome thing – busy with tourists, but as it turned out very favorable.

Space, generally, requires a lot of money. Considering that not every person can afford to buy a car, it to deal with space transportation passengers can afford not every rich country. Probably, for this reason, we seek cheaper ways of delivering goods or passengers to low earth orbit. Continue reading

Space probe approaching Pluto after 9 years

The NASA probe New Horizons close to Pluto and will be able to enter the planet’s atmosphere in July of this year

The ship, which was launched back in 2006 has come nearer to the outer body at a distance that allows you to make high-quality pictures of its surface.

NASA may have to adjust its trajectory in case of detection of unknown cosmic bodies, reports Russia Today .

Apart from the modern equipment on Board the spacecraft is an urn with the remains of the discoverer of Pluto Clyde Tombaugh (1906-1997), CDs with a message to aliens, U.S. coins, flags and postage stamps. On Board the SPACECRAFT is the CD 434 738 names of people who participated in the campaign NASA “Send your name to Pluto” (Send Your Name to Pluto).

Task apparatus is the study of the atmosphere and the ground layers of Pluto, moreover, New Horizons will create a map of the surface of the farthest planet in our System. Continue reading
