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

Giant planet was found at a distance of 25 000 light years from us

25 000 light years from Earth discovered a huge planet eight times bigger than Jupiter

An international team of astronomers has discovered a world that is 2,500 times the size of Earth.

A planet called MOA-2011-BLG-322 about 8 times that of Jupiter, which is the largest planet in our solar system. Astronomers believe it orbits around a star, distant from us at a distance of 25 000 light-years and with a mass equal to a third of the Sun.

Huge world, exceeding the size of the Earth 2,500 times, was discovered by an international team of astronomers. Artistic representation of an unknown planet

As reported by Ian O’neill in Discovery News, the giant planet was discovered using a technology known as “microlensing”.

Microlensing uses the General theory of relativity of albert Einstein, which assumes that gravity is actually the curvature of space and time. Continue reading
