Uranus Facts

Uranus is the seventh planet from the Sun. It is not visible to the naked eye, and it became the first planet discovered with the use of a telescope. Uranus turns sideways with an axial inclination of 98 degrees. It is often described as "rolling around the Sun sideways."

Here Are Some Incredible Scientific Facts About Uranus



  • • Uranus was officially discovered by Sir William Herschel in 1781.


  • It is too dim to have been seen by the ancients. At first, Herschel thought it was a comet, but several years later it was confirmed as a planet. Herscal tried to have his discovery called "Georgian Sidus" after King George III. The name of Uranus was suggested by astronomer Johann Bode. The name comes from the ancient Greek deity Ouranos.


  • • Uranus spins on its axis once every 17 hours, 14 minutes.


  • • The planet rotates in a retrograde direction, opposite to the way Earth and most other planets rotate.



  • • Uranus travels around the Sun every 84 Earth years.


  • During some parts of its orbit, one or the other of its poles point directly to the Sun and receive about 42 years of direct sunlight. The rest of the time they are in the dark.


  • • Uranus is often referred to as an "ice giant" planet.


  • Like the other gas giants, it has a top layer of hydrogen, which has mixed helium. Below is an "icy mantle," which surrounds a core of rock and ice. The upper atmosphere is made of water, ammonia and methane ice crystals that give the planet its pale blue color.


  • • Uranus reaches the coldest temperatures of any planet.


  • With a minimum atmospheric temperature of -224 ° C, Uranus is the coldest planet in the solar system. While Neptune is not as cold as Uranus, on average it is colder. The upper atmosphere of Uranus is covered by a mist of methane that conceals the storms that take place on cloud covers.


  • • Uranus has two sets of very fine dark rings.


  • The ring particles are small, ranging from dust-sized particles to small rocks. There are eleven inner rings and two outer rings. They probably formed when one or more of Uranus' moons broke into an impact. The first rings were discovered in 1977 and the two outer rings were discovered in images from the Hubble Space Telescope between 2003 and 2005.


  • • The moons of Uranus are named after the characters created by William Shakespeare and Alexander Pope.


  • These include Oberon, Titania and Miranda. All are frozen worlds with dark surfaces. Some are mixtures of ice and rock. The most interesting moon of Urania is Miranda; It has ice cannons, terraces and other strange surfaces.


  • • Only one spacecraft has flown through Uranus.


  • In 1986, the Voyager 2 spacecraft passed through the planet at a distance of 81,500 km. He returned the first foreground images of the planet, its moons and rings.

The average temperature of the planets

Within the Solar System, the average temperature on: • Pluto is around -235°C, • Neptune around -220°C, • Uranus -210°C, • Saturn -184°C, • Jupiter -153°C. • The temperature on Mars varies between about -87°C and -5°C, with an average of around -46°C. • The lowest natural temperature on Earth (recorded at Vostok, Antarctica in 1983) is -89°C; the highest surface temperature on Earth (recorded at Al 'Aziziyah, Libya in 1922) is 58°C; the mean overall temperature on Earth is 14°C. Planet Biography. Planets Surface Temperatures. Why temperatures differs from planets to planets? In general, the surface temperature decreases as the distance from the sun increases. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface above the lead's melting point of 880 ° F (471 ° C).

The Difference Between Being Intelligent And Being Wise

Intelligent : •   wise, cunning, capable of thinking and reason Wisdom: • The state of being wise • Ability to use knowledge and / or experience wisely • Able to determine what is wise against what is unwise • A saying, a philosophy or other advice considered wise In Short:  An intelligent man has a whole sea of knowledge and knows every fact. On the other hand, a wise man does not have all the knowledge that an intelligent man has, but he has the brain to know when to use knowledge. I have seen a lot of smart people make really stupid decisions. I was one of those people! The information I had before and after these decisions has not changed. But with every wrong decision, if I was willing to learn, my level of wisdom changed. The main difference is that: A smart or intelligent person knows how to solve any problem. A wise person knows how to avoid this problem. Knowledge makes a person intelligent. Experience makes a person wise.

Electric Flux

Electric field can be quantitatively described by using the concept of electric flux. Electric flux is the number of electric field lines penetrating a surface or passing through a surface. The electric field can be uniform or non-uniform. Let us now try to find the electric flux passing through a surface when the field is uniform.

10 Things That Nobody Will Tell You About Life

• If you are unemployed for a long time, no one will give you value or courage, not even your loved ones.

Silt

Silt is granular material of a size somewhere between sand and clay, whose mineral origin is quartz and feldspar. Silt may occur as a soil or as sediment mixed in suspension with water (also known as a suspended load) in a body of water such as a river. It may also exist as soil deposited at the bottom of a water body. Silt has a moderate specific area with a typically non-sticky, plastic feel. Silt usually has a floury feel when dry, and a slippery feel when wet. Silt can be visually observed with a hand lens. Sources:- Silt is created by a variety of physical processes capable of splitting the generally sand-sized quartz crystals of primary rocks by exploiting deficiencies in their lattice. These involve chemical weathering of rock and regolith, and a number of physical weathering processes such as frost shattering and haloclasty. The main process is abrasion through transport, including fluvial comminution, aeolian attrition and glacial grinding. It is in semi-arid envir...
