Spectroscopic observations have revealed the presence of crystalline water ice on the surface. It is speculated that Oberon may possess a liquid ocean layer at the core-mantle boundary. Oberon is the most reddish Uranian moon, and the most heavily cratered implying that it has the oldest surface among the satellites.
Uranus has thirteen distinct ring systems thought to have formed about million years ago from the collision of possible other moons or big objects. With this low albedo they appear dark as charcoal and another unique feature is that they are extremely narrow. The widest of the rings is called the epsilon ring, spreading from 20 to kilometers wide.
In , nine distinct rings were discovered, two more in and by an additional two. Most of them are opaque and consist of large bodies 0. Their radii range extends from about With new technologies coming up, Uranus is definitely a target for future studies and some missions have already been announced though it remains to be seen if they will take place.
Uranus Facts Uranus has a very unique rotation—it spins on its side at an almost degree angle, unlike other planets. Home » Planets » Gas Giants » Uranus. However, in Sir William Herschel announced its discovery being the first planet discovered with the help of a telescope. It was given the name Uranus, after the Greek god of the sky Ouranos.
It is the only planet whose name is derived directly from a figure of Greek mythology. The mean apparent magnitude of Uranus is 5. Uranus is the seventh planet from the Sun , around 1.
It has the third-largest planetary radius and fourth-largest mass in the Solar System. It has a radius of It is on an average distance of Its actual distance can be checked online as Uranus is constantly tracked. The gravity on Uranus is about 8. It orbits the sun quite unusually, being the only planet whose equator is nearly at a right angle to its orbit, with a tilt of Because of this, it rotates in the opposite direction than most planets, from East to West.
Venus also does this but Uranus is the only known planet to rotate on its side. It takes Uranus 84 years to complete an orbit of the Sun, the longest from all the planets in the solar system. It also has the shortest day. One rotation on Uranus takes about 17 hours. Uranus has the coldest planetary atmosphere in the solar system, degrees Celsius; degrees Fahrenheit.
Uranus and Neptune share similar composition, both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. Because of this Uranus and Neptune are classified as ice giants rather than gas giants, for easier distinction.
Though it appears featureless, without the cloud bands or storms associated with the other giant planets, it does have complex, layered cloud structure with water thought to make up the lowest clouds and methane the uppermost layer of clouds. Through analysis, the interior of Uranus has been stated to be made up primarily of ices and rock.
Uranus has 13 known rings around it. The innermost rings are narrow and dark, and its outermost rings are brightly colored. Like the other gas giants, it also has a magnetosphere and many moons.
Until now, 27 moons have been discovered orbiting Uranus. They were named after characters from the works of William Shakespeare and Alexander Pope. Uranus has been visited only once by a spacecraft: Voyager 2. Formation Through simulations after the Nice model, it has been suggested that both Uranus and Neptune formed closer to the sun and later drifted away.
Orbit and Rotation It takes Uranus about 7 years to pass through each zodiac constellation, and a total of 84 years to make a complete trip around the sun. Axial tilt The axis of rotation is approximately parallel with the plane of the Solar System, with a tilt of Atmosphere Uranus lacks a well-defined solid surface in its interior. Moons Like other giant planets Uranus has many moons. Miranda Miranda is a spherical moon and one of the strangest places in the solar system.
Ariel It is the fourth largest of the known moons of Uranus, the second smallest after Miranda, and it orbits and rotates in the equatorial plane of its parent planet. Umbriel Also discovered by William Lassell in , the moon consists mainly of ice and only a fraction of rock. Titania The largest moon of Uranus, and the eight largest moon in the Solar System with a diameter of 1, kilometers or miles. Oberon Oberon is the outermost major moon of Uranus.
Planetary Rings Uranus has thirteen distinct ring systems thought to have formed about million years ago from the collision of possible other moons or big objects. Future plans for Uranus With new technologies coming up, Uranus is definitely a target for future studies and some missions have already been announced though it remains to be seen if they will take place.
Did you know? In , Uranus will complete its third orbit around the sun since its discovery in The planet returned to the point of its discovery twice since then, in and , one day later each time. Because of its brightness, the planet can be seen in urban conditions on a good night, even without binoculars.
Methane has prominent absorption bands in the visible and near-infrared, making Uranus aquamarine or cyan in color. Between - , the closest approach of Uranus to Earth will happen in at a distance of Sources: [1.
Eventually, the moon could have been knocked out of orbit by another planet, a bit like a game of cosmic pinball. As for Venus, our closest neighbour, scientists have suggested that it started off rotating counter-clockwise, then slowed down to be almost static, before starting to spin clockwise like it does now.
This might explain the planet's very slow rotation speed today — it takes Venus Earth days to rotate fully, but only Earth days to orbit the Sun. So if you lived on Venus, your days would be longer than your years and the Sun would rise in the west. How does that happen to a planet? Astronomers think that the Sun's strong gravitational pull on the dense atmosphere of Venus; the atmospheric tides that would create; and the tidal pulls from other planets, could all have combined to reverse the planet's spin.
