While it “calculated” on the computer
In 2006, the Solar system lost one of the nine planets — Pluto stripped of planet status due to negligible size. But the discovery of American scientists threatens to return the ninth planet in the system — found a new celestial body, claiming the title.
The staff of the California Institute of technology Michael brown and Konstantin Batygin has published a paper in the reputable scientific journal “Astronomical journal” about his study, in which they “discovered” a new planet in the Solar system.
Celestial body has a mass of 5-10 times larger than our planet, and is about 20 times farther from Earth than Neptune. Despite the fact that Neptune is the most distant planet, until it 4300 million kilometers. Accordingly, before “the ninth planet” – about 8600 million. The problem is that open planet. while no one was looking through a telescope, it was discovered through computer simulation. However, the accuracy of such simulations is very high today.

Unlikely in 1930, when the world learned of the existence of Pluto, someone could believe that someday people will be able to find there their last resting place. However, this can happen very soon. NASA space ship with the remains of Clyde Tombaugh, discoverer of Pluto, had almost reached the destination. The journey of the ship lasts for more than 9 years. Soon NASA promises to publish the first pictures from the distant dwarf planet, the study of which may help answer many questions about the origin of the entire Solar system.
kosmicheskiy the NASA New Horizons spacecraft has begun to explore Pluto. The aircraft approached the icy dwarf so much that this week the staff of the American space Agency promise to show him the first Pictures. The input apparatus into the atmosphere of the dwarf planet is scheduled for July 2015.
Note that the distance to Pluto is 30 times more than from the earth to the Sun, and the spacecraft New Horizons was launched back in early 2006. On his way the machine New Horizons flew past Jupiter and Saturn, in the literal sense, rebounding from their orbits, which gave the ship a significant acceleration. Up to this point most distant mission was considered an American Kosmicheskaya flight of Voyager, which in 1980 had reached Saturn. Continue reading
Jupiter thousands of years ago named after the king of Roman gods, and reigns among the nine planets of our Solar system, rivaling the Sun in its splendor. The largest planet is located far beyond the main asteroid belt. The mass of Jupiter exceeds the mass of all other planets combined.
Jupiter is the largest planet in the Solar system. The semimajor axis of Jupiter’s orbit is 5.2.e. the eccentricity of the orbit e = 0,0489, the period orbits – 11,867 years. The inclination of the orbital plane to the plane of the Ecliptic is 1°1817″. The average speed along the orbit – about 13.1 km/s.
The period of rotation around the axis is 9 hours and 55 minutes. Each dot on the equator moves at a speed of 45 thousand miles per hour. Due to the centrifugal force of Jupiter is noticeably flattened (compression rate greater than 6 %). Since Jupiter is not a solid ball, and consists of gas and liquid, the Equatorial parts rotate faster than the polar regions. The rotation axis of Jupiter is nearly perpendicular to its orbit, therefore, the planet has no seasons.
The mass of the planet is M = 318 M = 1,9∙10 27 kg, radius R = 11,2 R = 71 492 km, However, Jupiter is very thin: its density is 1.33 g/cm 3. which is four times less than the density of the Earth. The acceleration of gravity at the level of the cloud surface of Jupiter sostavljaet = 2,53 g. Continue reading
