Uranus
Uranus (Uranus) is the first planet discovered in modern times of Mercury, Venus, Mars, Jupiter and Saturn are known since antiquity. Uranus was discovered by William Herschel (William Hershel) amateur astronomers Germans who settled in England have used the camera. Size 6.4 inch telescope he invented itself through the sky in a systematic way. And discovered Uranus on March 13 1781, he initially thought the object he found was a comet. But after several weeks of follow-up observations. Herschel has calculated the orbit of the objects he discovered and found that such objects are stars. Fortunately sun orbiting the sun beyond the orbit of Saturn's to two times
Uranus orbits the Sun, one round at a time, 84 years of world-style revolution, the most prominent of Uranus is the core of the star tilt. 98-degree angle to the plane of the solar angle or too little. Uranus, it rotates on its axis in the side. As a result of Uranus season long side of the star will be in the winter, the 42-year-old, while the other half is in the summer for 42 years,
that is, at some point on Uranus. Sun will not fall at all in the last 42 years, and contrast. Some areas will not receive any sunlight for 42 years as well as this turns up, however, because Uranus is very far away from the sun. Energy from the sun is so spread out to Uranus, only 0.27% of the energy that radiated out to the world, "winter" and "summer" on Uranus are at different temperatures around 2 ° C,
Uranus has rings like. The other gas planets ring of stars precipitation Rain McCluskey was discovered in 1977 by astronomer from Cornell University's (Comell University), USA. The phenomena observed Uranus moving cover one star. The astronomers found that a short time before the star disappeared on the edge of Uranus. Starlight gone dark and back to light up the new nine times and the presence of dark and bright stars, it happens in the same way again. When Uranus was orbiting the star, astronomers now conclude that Uranus has a ring of nine rings around stars usually lighter than would be observed from Earth. But when the star is moving to see the stars for several times that
Uranus has 21 known moons moon (August 2003) called all. Of these, the moon five planets core with a radius of over 200 km is Titania (Titania) Obi Ron (Oberon), Rona Gabriel (Umbriel), Ariel (Ariel) and Miranda (Miranda) (Sort. by size from largest to smallest) of the moons of Uranus data tables in the Appendix. It is obvious that the moon is lower than 1000 kilometers are not distorted spherical. This theory supports the incorporation into the sphere of the planet as well.
