Published January 11, 2019 Updated August 15, 2019. Uranus owes its vibrant blue-green hues not from unusual oceans but from an upper atmosphere flush with methane, which absorbs the sun's red light and scatters blue light back to our eyes. Voyager 2 captured the planet during its solstice, when one pole was bathed in sunlight and so kept a constant temperature. But to know for sure, researchers would need a closer look. Since ancient times it was not recognized due to its dimness and slow orbit. Ancient people had already scanned the skies and discovered six of the nine planets that we recognize today (the other modern discoveries were Neptune and Pluto (now classified as a dwarf planet), too dim to the naked eye). Uranus is too dim for ancient civilizations to have seen it. This means that maybe planets can be created by impact too. The gas giant is tipped on its side, spinning on its axis at nearly a right angle to its orbital path around the sun, which requires a lengthy 84 Earth-years to complete. The planet is also remarkable for its dramatic tilt, which makes its axis point almost directly to the sun. But the icy winds of Uranus can uproot trees, dislodge houses and do a lot more damage in seconds than we’ve seen on Earth. 4. Uranus is an ice giant (instead of a gas giant). Uranus is surrounded by a set of 13 rings. Uranus is the seventh planet away from the Sun – only Neptune is further away.

Planet Uranus facts The mean radius of Uranus is ~ 25,362 km (~ 3 times that of Earth). The orbital speed … Near the core, it heats up to 9,000 degrees Fahrenheit (4,982 degrees Celsius). This is why there has been no mention of Uranus sightings before William Herschel saw it through his telescope in 1781. Compare with Earth temperatures, where the coldest it’s got in recent years was a record -93.2 degrees C in Antarctica in 2013. Like Venus, Uranus has what's known as a retrograde rotation, turning on its axis in the opposite direction to the rest of the planets.

That sets the planet's auroras out of line, making them appear far from the poles, unlike those on Earth. In fact, Uranus has a thick, smoggy atmosphere that becomes denser the deeper you go. Uranus and Venus turn in a retrograde direction … So if you were weighed on Uranus, you would weigh only 0.89% of your actual weight on Earth. Uranus is the \"butt\" of more than a few jokes and witty (and not so witty) puns, but it's also a frequent destination in various fictional stories, such as the video game Mass Effect and TV shows like Doctor Who. It was discovered in December 13, 1781 by William Herschel, a German-born British astronomer. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. Like most of the planets in our solar system, Uranus revolves around the Sun in an eccentric orbit (0.046), thus the distance between them varies throughout the year. This makes Uranus the third-largest by size. Such a discovery has somewhat changed the way we think about the formation of planets in our solar system. All Rights Reserved. The minimum temperature amongst the atmosphere on Uranus is -224°c. While Saturn wears the crown for the least dense planet in our celestial family, Uranus is not far behind: Most of its mass is made up of an icy dense fluid of water, ammonia, and methane. Uranus gets its blue-green color from me… Uranus is one of two ice giants in the outer solar system (the other is Neptune). 21 Amazing Facts About Uranus 1. Uranus is one of the four planets in the solar system that is a gas planet. It has an equatorial diameter of 51,000 km and a polar diameter of 49,900 km. But you can’t see Uranus. Apart from it’s slightly odd and funny name, what else is there to know about this beautiful planet? It is surrounded by 13 narrow rings made of chunks of dark material. Uranus Facts. Uranus, with its featureless, blue-green disk, is the only planet to be named after a Greek and not a Roman god. Uranus is 400% the size of Earth. Something really big – many times bigger than the earth – may have crashed into Uranus a long time ago and thrown the planet on its side. It is the second least dense planet; Saturn is the least dense of all. If you look in the direction of Uranus through a telescope, you will see a bluish-greenish disk. This kind of extreme temperature difference creates seasons as long as 20 years. Uranus, the seventh planet from the sun, may initially look like a bland, blue-green ball. He had been surveying stars, including those that were ten times dimmer than visible stars. It Gets Its Name From the Greek God of The Sky. Unlike the gas giants Jupiter and Saturn, which are mostly made up of... Uranus has the coldest temperature of … Uranus is too dim for ancient civilizations to have seen it. Uranus was the first planet to be discovered with the help of a telescope. © 1996-2015 National Geographic Society, © 2015- It has the fourth-largest mass in the Solar System.

Uranus is icy and burning hot, with extreme seasons. Uranus has 27 moons, Jupiter has 67 while the Earth has just one. The craft came as near as 50,600 miles to Uranus' cloud tops in 1986, giving scientists their first detailed peek at both the planet and its many curious moons. Different parts of the orb absorb the sun's rays during its 17-hour-long day, and the difference in temperature drives a swirl of storms. 14. Only one spacecraft, Voyager 2, has ever flown by Uranus at close range. The pressure on the surface is around 1.3 times that of the earth and the gravity is about 0.9 times that of Earth. For example, if you were to fall off your spacecraft over Uranus, you’d probably find yourself half-falling and half-swimming through the planet’s atmosphere. Wind speeds on giant planets can be as much as 15 times stronger than winds on Earth. 10. But when Uranus moves toward its equinoxâa period of time when day and night are of equal lengthâthe sun illuminates the planetâs equator. Jupiter is barely tilted at an angle of 3 degrees. The last of these 27 moons was discovered in 2003. Uranus was the husband of Gaia, the goddess of the Earth. 1. By Benjamin Elisha Sawe on November 6 2019 in Environment. Elements of this image furnished by NASA. 24. But follow-up observations have since shown that there's more there than initially meets the eye. Uranus is named after a Greek god, not Roman, like other planets. The tilt of Uranus may have been caused by a collision. Uranus revolves in its orbit at a speed of 6.6 km/sec while Mercury is the fastest planet in this regard at 47.87 km/sec. Uranus is a very cold and windy planet, and it is filled with ice. 47. What this means is, there’s probably not a lot of weather activity going on deeper into the giant planet of Uranus. When it was accepted as a planet years later, Herschel lobbied to call the discovery Georgium Sidus after King George III. 3. In other words, a 10 feet dunk on Earth would equate to an 11 feet dunk on Uranus. 5. The planet’s color comes from the 2 percent methane gas in its atmosphere, along with mostly hydrogen (83 percent) and some Helium (15 percent). But there's a lot to love about the icy giant, from its 13 rings to its 27 known moons to the fact that it may even rain diamonds from its hazy atmosphere. Seen from Earth, the very faint rings of Uranus appear to encircle the planet from top to bottom. 48. Methane makes it aquamarine or cyan in color. 9. There’s a high chance that the reason for Uranus’s lopsided spinning is the many collisions it has suffered. What's more, Uranus's methane acts like a blue shroud, obscuring the features that lie below to telescopes operating in optical light. A lot of other names had been rejected in the naming of Uranus. And that's not the only strange thing about its spin. The temperature of Uranus is over 350 degrees Fahrenheit below zero or over 220 degrees Celsius below zero! While Planet Uranus is visible to the naked eye because of the dimness of the planet and the slow orbit, it was long mistaken as a star. The British astronomer thought it was a comet or a star. Cold, windy Uranus looks like a planet on its side. Uranus, seventh planet in distance from the Sun and the least massive of the solar system ’s four giant, or Jovian, planets, which also include Jupiter, Saturn, and Neptune. Uranus Facts Uranus was discovered in 1781 by William Herschel, and it is the seventh planet away from the sun. William Herschel, the astronomer who discovered it, originally wanted to name it “George’s Star” after King George III, but that didn’t stick. This may have happened at the beginning of the solar system when the moons of Uranus were still balls of gas. It's tipped nearly 60 degrees from the axis of rotation. That’s not exactly supersonic speed (the speed of sound in air is 750 miles per hour) so a stationary jet in the path of the crashing wind won’t experience a sonic boom like it would on Neptune. The lack of thermal change keeps winds to a minimum, making the planet seem bland and static. It is designated by the symbol ♅. https://www.nationalgeographic.com/science/space/solar-system/uranus.html, first of three planets in our solar system, Berkeley Research: Amateur, professional astronomers alike thrilled by extreme storms on Uranus, University of Texas McDonald Observatory: Big Blue Planet. Here are some other interesting facts about Uranus, the oddball planet, that we bet will fascinate you. Uranus has the coldest atmosphere in the solar system and it’s not hard to see why. Voyager 2's flyby also revealed 10 previously undiscovered moons and two new rings, and its data continued to be a trove of information long after the spacecraft sailed by. Winds on Uranus can travel as fast as 560 miles per hour. He may have preferred ‘Uranus’, and so that’s what this planet beyond Saturn came to be called. These included Hypercronius (which means ‘above Saturn’) and even the dreadful Georgium Sidus (meaning ‘The Georgian Planet’) with which Herschel wanted to flatter the then-King of England George III.
