1. Uranus

   Uranus is the seventh planet from the Sun. It is named after Greek sky deity Uranus (Caelus), who in Greek mythology is the father of Cronus (Saturn), a grandfather of Zeus (Jupiter) and great-grandfather of Ares (Mars). Uranus has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. The planet is similar in composition to Neptune, and both have bulk chemical compositions which differ from those of the other two giant planets, Jupiter and Saturn (the gas giants). For this reason, scientists often distinguish Uranus and Neptune as "ice giants". As with gas giants, ice giants lack a well-defined solid surface. Uranus's atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. It has the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 kelvins (−224 °C; −371 °F). It has a complex, layered cloud structure; water is thought to make up the lowest clouds and methane the uppermost layer. The planet's interior is mainly composed of ices and rock.Like the other giant planets, Uranus has a ring system, a magnetosphere, and numerous moons. The Uranian system has a unique configuration because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. Therefore, its north and south poles lie where most other planets have their equators. In 1986, images from Voyager 2 showed Uranus as an almost featureless planet in visible light, without the cloud bands or storms associated with the other giant planets. No other spacecraft have yet visited the planet. Observations from Earth have shown seasonal change and increased weather activity as Uranus approached its equinox in 2007. Wind speeds can reach 250 metres per second (900 km/h; 560 mph).

1. uranus

   Uranus is the seventh planet from the Sun in our solar system. It is known for being a gas giant composed primarily of hydrogen and helium, with a unique characteristic of having its axis tilt sideways, meaning it spins on its side. This results in its north and south poles being located where other planets have their equator. Uranus, which is conspicuous by its pale blue-green color, was discovered in 1781 by British astronomer William Herschel, making it the first planet to be discovered with a telescope. It also has a complex ring system, 27 known moons, and takes approximately 84 Earth years to complete one orbit around the Sun.

1. Uranus

   Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both are of different chemical composition than the larger gas giants Jupiter and Saturn. For this reason, astronomers sometimes place them in a separate category called "ice giants". Uranus's atmosphere, although similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, contains more "ices" such as water, ammonia, and methane, along with traces of hydrocarbons. It is the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K. It has a complex, layered cloud structure, with water thought to make up the lowest clouds, and methane thought to make up the uppermost layer of clouds. In contrast, the interior of Uranus is mainly composed of ices and rock. It is the only planet whose name is derived from a figure from Greek mythology rather than Roman mythology like the other planets, from the Latinized version of the Greek god of the sky, Ouranos. Like the other gas giants, Uranus has a ring system, a magnetosphere, and numerous moons. The Uranian system has a unique configuration among the planets because its axis of rotation is tilted sideways, nearly into the plane of its revolution about the Sun. Its north and south poles therefore lie where most other planets have their equators. In 1986, images from Voyager 2 showed Uranus as a virtually featureless planet in visible light without the cloud bands or storms associated with the other giants. Terrestrial observers have seen signs of seasonal change and increased weather activity in recent years as Uranus approached its equinox. The wind speeds on Uranus can reach 250 meters per second.

1. Uranus

   a planet, the outermost but one of the solar system, is 1770 millions of miles from the sun, takes 30,686 of our days, or 84 of our years, to revolve round it, has four times the diameter of the earth, and is accompanied by four moons; it was discovered in 1781 by Herschel, and called by him Georgium Sidus in honour of George III.

2. Uranus

   in the Greek mythology the son of Gaia (the Earth), and by her the father of the Titans; he hated his children, and at birth thrust them down to Tartarus, to the grief of Gaia, at whose instigation Kronos, the youngest born, unmanned him, and seized the throne of the Universe, to be himself supplanted in turn by his son Zeus.

Examples of uranus in a Sentence

1. Suzanne Dodd:

   We need to develop an orbiter for each of those planets, at Uranus, the five major moons are very different. They have unique geological history, so we need to understand how they were formed or captured. Uranus has a rotational pole that is tipped on its side more than the Earth, so we need an understanding of why that happened. At Neptune, there are a great amount of features in atmosphere similar to Jupiter and Saturn. And Neptune's moon Triton is of interest because of the methane geysers on it.

2. Amy Simon:

   If you think back to the original Voyager pictures of Uranus, it was just kind of a pale blue ball with nothing on it. You didn’t see clouds, you didn’t see haze, you didn’t see anything … so there was a polar cap then, but we couldn’t see it, what we’ve been watching over time (using Hubble), is this buildup of this high-altitude haze in the atmosphere, and the exact purpose or the exact mechanism behind it, we don’t know, that’s one of the things we’re studying.

3. Alyssa Rhoden:

   Evaluating Mimas' status as an ocean moon would benchmark models of its formation and evolution, this would help us better understand Saturn's rings and mid-sized moons as well as the prevalence of potentially habitable ocean moons, particularly at Uranus. Mimas is a compelling target for continued investigation.

4. Naomi Rowe-Gurney:

   The JWST gives us the ability to look at both Uranus and Neptune in a completely new way because we have never had a telescope of this size that looks in the infrared, the infrared can show us new depths and features that are difficult to see from the ground with the atmosphere in the way and invisible to telescopes that look in visible light like Hubble.

5. Amy Simon:

   We’ve gotten quite used to seeing a lot of big change on Jupiter. We see the clouds change color, we see storms coming, we’ve been watching the Great Red Spot — I would love to see a big storm outbreak on Uranus, because that’s one of the few places where we don’t tend to see that very much, if we saw a big storm develop on Uranus (using Hubble), I’d be pretty excited.
