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

Soon everyone will fly into space

Long-standing plans by British billionaire Richard Branson about the organization of space flights is nearing realization. Recently, the head of the Virgin group of companies presented the public with aircraft with a rocket engine called SpaceShipTwo, which will be used for commercial flights into space.

“I know that there are literally thousands wanting to be in space to be able to look out the window, admiring the beautiful Land,” — said the billionaire. At the presentation of SpaceShipTwo in California, he said, dreamed of going into space since then, as seen on TV landing on the moon. Presents the aircraft will undergo tests over the next 18 months, before the first tourists will be able to take a short excursion outside the Earth’s atmosphere. About three hundred people have already applied for the flight is $200 thousand during the six minutes of weightlessness.

SpaceShipTwo, built from lightweight composite materials based on carbon and is equipped with a rocket engine on a hybrid fuel. The basis for its development was the project SpaceShipOne — aircraft, lifting into the air booster. He became the world’s first private space ship and made a series of flights in 2004, reports the BBC . Continue reading

Brown and Batygin told about the discovery of the ninth planet of the Solar system

Scientists shared their impressions

21 January 2016, two scientists from the California Institute of technology, Professor Mike brown and Professor Konstantin Batygin has officially announced that they have found a ninth planet in our Solar system. According to their mathematical models, it is a gas giant like Uranus or Neptune, the mass of the discovered planet 10 times the mass of Earth, it rotates in an orbit 20 times larger than the earth and it requires from 10,000 to 20,000 years to make one complete revolution around the Sun. However, very reliable model of scientists has demonstrated and existing telescopes have not yet managed to see her.

Scientists have been very mixed on the nature of their activities and perhaps that is why they have achieved such amazing results. So brown has increasingly resorted to methods of observation and explores distant objects in our Solar system, whereas Batygin relies more on the laws of physics and mathematical calculations. Apparently, that tandem allowed the researchers to calculate the so-called ninth planet. Continue reading
