Uranus is a planet.

Uranus is similar to Neptune.

Uranus has 27 known natural satellites.

Neptune is very similar to Uranus.

It is also designated Uranus XV.

The moon is also designated Uranus II.

Puck ( ) is an inner moon of Uranus.

A New Frontiers Uranus Orbiter has been evaluated and recommended in the study, The Case for a Uranus Orbiter .

But it visited Jupiter, Saturn, Uranus and Neptune.

Uranus is the seventh planet from the Sun.

Uranus' atmosphere is made up of hydrogen, helium, and methane.

Uranus reached its most recent equinox on December 7, 2007.

The dipole moment of Uranus is 50 times that of Earth.

The Solar System has four gas giants Jupiter, Saturn, Uranus, and Neptune.

When William Herschel discovered Uranus, he at first thought he had discovered a comet.

Uranus has 27 known satellites, the largest ones being Titania, Oberon, Umbriel, Ariel, and Miranda.

The outer planets are large gaseous spheres with rings and include Jupiter, Saturn, Uranus, and Neptune.

The wind speeds on Uranus can reach 250 metres per second (900 km h, 560 mph).

Uranus has relatively well developed aurorae, which are seen as bright arcs around both magnetic poles.

The rapid rotation of Uranus causes winds up to 600 kilometers per hour to blow in its atmosphere.

There are 8 planets in our solar system there's Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Uranus was also examined as part of one trajectory for a precursor interstellar probe concept, Innovative Interstellar Explorer.

Neptune Neptune (30.1 AU), though slightly smaller than Uranus, is more massive (equivalent to 17 Earths) and hence more dense.

The reasoning was presumably that Uranus, as god of the sky and air, would be attended by spirits of the air.

The names of all four satellites of Uranus then known were suggested by John Herschel in 1852 at the request of Lassell.

Titania is the largest of the moons of Uranus and the eighth largest moon in the Solar System at a diameter of .

Uranus is unique in our solar system because it is tilted 98 degrees. When viewed from Earth, it appears to rotate on its side!

Uranus magnetic field and rotation axis are out of alignment by 59 degrees, unlike Earth s, whose magnetic field and rotation axis are nearly aligned.

All inner moons are intimately connected to the rings of Uranus, which probably resulted from the fragmentation of one or several small inner moons.

Uranus tilts over so far on its axis that it rotates on its side. Because of this, its poles are sometimes pointed almost directly at the Sun.

The temperature in Uranus' upper atmosphere is so cold that the methane condenses and forms a thin cloud layer which gives the planet its blue green appearance.

It was thus believed for many decades thereafter that Uranus had a system of six satellites, though the four latter moons were never confirmed by any other astronomer.

It might be produced locally from carbonates or organic materials under the influence of the energetic charged particles coming from the magnetosphere of Uranus or the solar ultraviolet radiation.

The names of all four satellites of Uranus then known were suggested by Herschel's son John in 1852, at the request of William Lassell, who had discovered the other two moons, Ariel and Umbriel, the year before.

Although William Herschel, the discoverer of Titania and Oberon, claimed at the end of the 18th century that he had observed four additional moons of Uranus, his observations were not confirmed and those four objects are now thought to be spurious.

While still an undergraduate, Adams performed an investigation to try to explain the reason for the irregularities in the motion of the planet Uranus. He theorized that the unexpected planetary orbit could be due to the presence of an as yet undiscovered planet.

Occurrence Occurrence of alkanes in the Universe Alkanes form a small portion of the atmospheres of the outer gas planets such as Jupiter (0.1 methane, 0.0002 ethane), Saturn (0.2 methane, 0.0005 ethane), Uranus (1.99 methane, 0.00025 ethane) and Neptune (1.5 methane, 1.5 ppm ethane).
