Subscriber Exclusive Content. Why are people so dang obsessed with Mars? Uranus is slightly larger in diameter than its neighbor Neptune, yet smaller in mass.

It is the second least dense planet; Saturn is the least dense of all. Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus' cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green color.

The planet is mostly swirling fluids. The extreme pressures and temperatures would destroy a metal spacecraft. Uranus' atmosphere is mostly hydrogen and helium, with a small amount of methane and traces of water and ammonia. The methane gives Uranus its signature blue color.

While Voyager 2 saw only a few discrete clouds, a Great Dark Spot, and a small dark spot during its flyby in — more recent observations reveal that Uranus exhibits dynamic clouds as it approaches equinox, including rapidly changing bright features. Uranus' planetary atmosphere, with a minimum temperature of 49K Wind speeds can reach up to miles per hour kilometers per hour on Uranus. But closer to the poles, winds shift to a prograde direction, flowing with Uranus' rotation.

Uranus has an unusual, irregularly shaped magnetosphere. Magnetic fields are typically in alignment with a planet's rotation, but Uranus' magnetic field is tipped over: the magnetic axis is tilted nearly 60 degrees from the planet's axis of rotation, and is also offset from the center of the planet by one-third of the planet's radius.

Auroras on Uranus are not in line with the poles like they are on Earth, Jupiter, and Saturn due to the lopsided magnetic field. The magnetosphere tail behind Uranus opposite the Sun extends into space for millions of miles.

Introduction The seventh planet from the Sun with the third largest diameter in our solar system, Uranus is very cold and windy. Potential for Life Potential for Life Uranus' environment is not conducive to life as we know it. Size and Distance Size and Distance With a radius of 15, Though, the planet has their north and south poles at their equate line instead of where most others would find them.

Esther Fleming August 8, The hydrogen in Uranus and Neptune is confined within a thin atmosphere and liquid molecular shell that do not extend to great depths and contribute only about 15 percent of the planetary mass.

These two planets do not have enough hydrogen, or sufficient mass and internal pressure, to squeeze the hydrogen into a metallic state. So there is no internal shell of liquid metallic hydrogen inside Uranus and Neptune. Although customarily denoted as ices, since they would be frozen at the cloud tops of these planets, these substances are kept liquid by the high temperatures, up to 8, degrees kelvin, deep in the planetary interiors.

These molecules will form from atoms of hydrogen, H, oxygen, O, carbon, C, and nitrogen, N, the most abundant heavy elements in the material from which the Sun and giant planets originated.

Uranus and Neptune are not unlike the cores of Jupiter and Saturn, which similarly contain 10 to 20 Earth masses of melted ice and molten rock. But Uranus and Neptune are almost all core, without the deep envelope of hydrogen and helium that make up most of the mass of Jupiter and Saturn.

The differences between these four planets apparently derive primarily from the amounts of hydrogen and helium that they were able to attract and hold as they formed. But the resemblance ends there. Here on Earth our magnetic pole is very near our geographic pole, which is very useful for navigation with a compass.

The magnetic and rotational axes of Jupiter and Saturn are also closely aligned. But they are way off kilter on both Uranus and Neptune. Unlike these two giants, there is no shell of liquid metallic hydrogen inside Uranus and Neptune, but electrical currents within their vast internal oceans might generate the magnetic fields.

It is probable that the electrical conductivity within Uranus and Neptune is provided by water-rich material that has a conductivity that is about two orders of magnitude less than that of metals. It is also likely that this conductivity comes from protons, not electrons, within the ionized waters. Another lucky incident occurred on 10 March , when the planet was scheduled to pass in front of a faint star. Because of uncertainties in the predicted time of the star's disappearance, one telescope was set into action about 45 minutes early.

Soon after the recording began, the starlight abruptly dimmed but then it almost immediately returned to normal, producing a brief dip in the recorded signal. At first, the dip was attributed to a wisp of cloud on Earth or to an unexpected change in the telescope's orientation.

But the star blinked on and off several times before and after the planet covered it. Moreover, each dip on one side of Uranus was matched by another one on the other side, at the same distance from the planet.

During the next few years, observations of more than stellar occultations by Uranus revealed the details of nine narrow rings.

From the brief duration of the dips of blocked starlight, astronomers concluded that all but one of the individual rings could be no wider than 10 kilometers. The relatively long time between the dips indicated that the threadlike rings are separated by hundreds of kilometers of nearly empty space. These skeletal, web-like rings are unlike any seen before, all very narrow and widely spaced from each other. When Voyager 2 arrived at Uranus in , nearly a decade after the discovery of its narrow rings, instruments on the spacecraft confirmed all the known rings, and added at least two.

They found the? The spacecraft also discovered at least 10 small moons that are located just outside the ring system. The particles in the main narrow rings of Uranus are both dark and large. They range between a softball and an automobile in size, or between 0.

And they contain very few smaller particles in the millimeter to centimeter, or 0. Broad sheets of dust were nevertheless detected in the wide gaps between the rings. The dust is lit up when the Sun shines through the rings, in the same way that grime on a car's windshield becomes visible when struck by the lights of an oncoming car.
