Uranus: A False Planet

Uranus was discovered by William Herschel and is 2.877 billion km away from the sun.

Neptune has 14 different moons. Neptune’s largest moon is called Triton. Triton is the only large moon in the solar system to orbit in the opposite direction to its planet’s rotation, this is known as a retrograde orbit. The distance of its orbit is 354,759 km. Its orbit period takes 5.9 days (retrograde). Triton was discovered by William Lassell. Neptune has 5 rings. Neptune is very cold compared to Earth. It is -214 degrees Celsius. Neptune is the smallest of the ice giants. Despite being smaller than Uranus, Neptune has a greater mass. Below its heavy atmosphere, Uranus is made of layers of hydrogen, helium, and methane gases. They enclose a layer of water, ammonia and methane ice. The inner core of the planet is made of

Uranus is the only giant planet whose equator is nearly at right angles to its orbit and has 5 large moons and 22 smaller moons. It is, also, the only planet in our solar system to spin on its side. Uranus

When was Neptune discovered?“Neptune was the very first planet to be discovered by using math! (mathematics). After the discovery of Uranus in 1781, astronomers noticed that the planet was being pulled a little bit out of its normal orbit. John Couch Adams of Britain and Urbain Jean Joseph Leverrier of France, used math to figure out that the gravity from another planet beyond Uranus was affecting the orbit of Uranus. They figured out not only where the planet was, but also how much mass it had. A young astronomer, Johann Gottfried Galle, decided to search for the predicted planet and observed Neptune for the first time in 1846.” -http://coolcosmos.ipac.caltech.edu/ask/146--When-was-Neptune-discovered-

Galileo spacecraft first discovered the four largest moon of Jupiter, called Io, Europa, Ganymede and Ganymede and Callisto. Ganymede is the largest moon in the Solar System Atmosphere And Planetary Composition: Temperature Range: The cloud-tops average 120 K=153*C=-244*F. Atmosphere: Jupiter is a gaseous planet; it does not have a solid surface like the Earth does (but probably has a solid, rocky core 10 to 15 times the mass of the Earth). When we look at Jupiter, we are seeing icy clouds of gases moving at high speeds in the atmosphere. Jupiter's atmosphere is composed of about 90% hydrogen and 10% helium.

Uranus was the very first planet to be discovered since the beginning of recorded history. William Herschel was a man of music, but he was also very interested in astronomy and often studied books about it. His love for astronomy is what ultimately led him to the discovery of the planet.

Uranus is about 3,499,756 football fields! The rotation of Uranus is 17 hours 14 minutes and the revolution of Uranus is equal to about 84 Earth years. Uranus has only been visited by one spacecraft, due to the straight alignment of plants that happens every 187 years. This spacecraft is known by the name of “ Voyager 2”, which flew by Uranus on January 24, 1986. The Voyager 2 has flown by the planets of Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and are now in interstellar space since takeoff on August 20, 1977. Uranus’s axis is unique compared to other planets’ axes, as this axis is almost parallel to the ecliptic. Uranus has 27 moons; the two largest are Titania and Oberon. Titania is covered with enormous canyons, one of which stretches from equator to pole. Oberon is relatively the same as Titania, although is ancient surface is covered

After researching about astronomy and the discovery of Uranus by William Herschel in 1781, I learned a lot about Uranus. I think one of the most shocking things about the discovery of Uranus was that William Herschel wasn’t even a professional astronomer, he was actually a musician. He did have an interest in astronomy on the side which is what led him to discover Uranus. He built many telescopes and he found the planet in one that he had built himself and at first he thought it was a comet. After studying it for many days, alongside many other astronomers, he discovered it wasn’t a comet at all. He and the astronomy community continued to study Uranus and they discovered how different it is from the other planets. I love how Herschel discovered

Uranus is named after ancient Greek deity of the sky, Uranus had Uranus has 27 known moons natural satellites They are all names after shake spare and Alexander pope The five main satellites are Miranda,Ariel,Umbriel,Titania and

“We saw Saturn today whose name comes from the Roman god of agriculture. Tomorrow, we will see the last two planets in our Solar System. First, will be Uranus or the Greek god of the sky and later, Neptune or the Roman god of the sea. These ice giants of frozen water, ammonia, and methane have much fainter rings than Saturn’s dramatic ones. From their far-flung locations at the edge of the Solar System, it takes eighty-four Earth years for Uranus to orbit once around the Sun in comparison with a hundred and sixty-five Earth years for Neptune. Additionally, Neptune is the only planet in the Solar System not visible from Earth without a telescope. Both planets have frozen landscapes, with an average temperature of minus two hundred and twenty-four degrees Celsius for Uranus and minus four hundred degrees Celsius for Neptune. The two planets appear blue due to the reflection of blue light by methane, a primary component in their atmosphere. Furthermore, the twenty-seven moons of Uranus have names from characters of William Shakespeare’s plays such as Juliet, Ophelia, and Puck. In contrast, Neptune’s thirteen moons have names from the Greek sea gods and mythical beings such as Triton and Larissa.”

Through studying Uranus, scientist have discovered that Uranus has a thick layer of gases that surround the planet, they have also found that there are

Since the time people have looked in the sky and studied stars, Uranus has been seen and know, but not as a planet, but instead as a star. Uranus was recorded in Hipparchus’ star catalogue (128 BC) as a star, and remained as a star until 1781 when William Herschel found something particular strange about the so called star.

William Herschel’s discovery of Uranus was the first “discovery…to be made in modern times…and also the first to be made by telescope”. While looking through the telescope, William “noticed

I studied William Herschel’s discovery of Uranus. Herschel first noticed Uranus when making observations late one night. He originally observed what he thought was a comet. He hypothesized that because no new planets had been thought to exist, yet he noticed a circular object moving through the solar system. Upon further observation, he observed that the object appeared to enlarge.

The knowledge of what the inner core is made up is still and will remain unknown until we can create a satellite that can make into the atmosphere of Jupiter and the other gas planets. Jupiter's atmosphere was also found to be quite turbulent. It is also know that Jupiter spins faster than any other planet. This indicates that Jupiter's winds are driven in large part by its internal heat rather than from solar input as on Earth. The vivid colors seen in Jupiter's clouds are probably the result of subtle chemical reactions of the trace elements in Jupiter's atmosphere, perhaps involving sulfur whose compounds take on a wide variety of colors, but the details are unknown. The colors correlate with the cloud's altitude: blue lowest, followed by browns and whites, with reds highest. Sometimes we see the lower layers through holes in the upper ones. Then we have the Great Red Spot that everyone can identify as Jupiter. This reddish color of the “Great Red Spot” is a puzzle to scientist, but several chemicals, including phosphorus, have been proposed as a reason. In fact, the color and mechanisms driving the appearance of the entire atmosphere are still not well understood. This spot has been seen by Earthly observers for more than 300 years. Robert Hooke discovered it in the 17th century. The GRS is an oval about 12,000 by 25,000 km, big enough to hold two Earths. Another interesting feature about Jupiter is that it
