The bland aquamarine face of Uranus bears witness to the fact that Uranus is enshrouded in clouds. The planet appears to be blue-green because the atmosphere absorbs the, red wavelengths of the visible spectrum, . The uniformity of the planet's appearance confirms that the planet's atmosphere is composed almost solely of one element, methane gas. There is a preponderance of haze, composed of ethane and other hydrocarbon ices high in the stratosphere, and clouds of methane ice low in the troposphere. The cloud particles constantly recycle themselves, first creating then destroying the heaviest crystals. This is an indication that Uranus' atmosphere is still evolving from its formation out of the solar nebula. Because Uranus lies on its side, Uranus has very strange seasons. Motions in the cloud patterns indicate that, like Jupiter and Saturn, the basic meteorology of Uranus can be described as a striped pattern of winds. This means that, even though the pattern is difficult to distinquish, Uranus is striped, just like Jupiter and Saturn.
Uranus has 21 fascinating moons and a complicated ring system. The ring system is a completely different form of ring system than that found at Saturn or Jupiter. At Uranus there is even a very obvious partial ring, or "ring arc".
Many moons are icy moons with fascinating surface features. These icy moons have neither an atmosphere nor a magnetosphere, and there is not much possibility for life. The surfaces of these moons indic...
The atmosphere of Uranus is thick with a lot of hydrogen, helium, and methane. It has a very low density, the mean density is 1271 kg/m³. Uranus lacks any really significant internal heat source and it mean surface temperature is 58° K.

Uranus is so far away that scientists knew comparatively little about it before NASA's Voyager 2 undertook its historic first encounter with the planet. The spacecraft flew closely past distant Uranus, and came within 81,500 kilometers (50,600 miles) of Uranus's cloudtops on Jan. 24, 1986. Voyager 2 radioed thousands of images and mass amounts of other scientific data about Uranus, its moons, rings, atmosphere, interior and magnetic environment. However, while Voyager has revealed much about the gas giant, many questions remain to be answered.
orbit is the most circular of any planet, with an eccentricy of less than 1%.
Did you know that PLANET X will pass through our solar system again in 2003 after approximately 3660 years of absence on its regular orbit? Like most people you probably do not know this. The knowledge has been kept away from the public for several reasons, one of which is to avoid causing panic among the world's population.
In 1609, Galileo Galilei, using “spyglass” which allowed one to see things closer than they appeared, made an early version of the telescope. With it, he observed the skies in a way no one had before. He discovered the moon isn’t perfectly globular, it has craters, the Sun has sunspots, Venus orbits the Sun (contrary to widespread belief in his time), and then he observed four “stars” around Jupiter (“Our Solar System”). Within days, he realized that these objects were not stars, they were moons. Io, Ganymede, Castillo, and Europa are known as the Galilean Moons or Satellites, collectively. During the 19th century, the first measurable physical studies of these moons became achievable when Simon de Laplace derived the satellite masses from their shared gravitational perturbations and afterward, other workers used a new generation of telescopes to measure the mass of these moons. The data collected showed that the density declined from the inner to the outer satellites. According to Adam Showman, “More recent observations of water ice on the surfaces of the outer three moons led to the inference that the satellite compositions range from mostly silicate rock at Io to 60% silicate rock and 40% volatile ices (by mass) at Ganymede and Callisto” ( 77). The Voyager flybys of Jupiter in 1979 exposed indication of extensive geological activity like Europa's fractured terrains, which probably result from tidal heating and bending...
Sixty-Five million years ago, 70 percent of life on Earth died. The most reasonable and possible reason this happened was an asteroid. An asteroid hit the Earth very hard, and in doing this, dirt and dust from the impact stayed in the air and it blocked out sunlight, that’s why the dinosaurs died. An asteroid is a rock from outer space. Asteroids have orbited the Sun along with the planets since the solar system formed about 4.6 billion years ago, but it’s only been 200 years since we first discovered them. Meteorites are small pieces of asteroids broken off on impact with other asteroids. Most meteorites are rusty brown on the outside, have rounded edges from melting as they go through Earth’s atmosphere, and contain iron. There are 3 different types of meteorites: stony, metallic, and stony metallic.92 percents of all asteroids are stone, 6 percent are made of iron and nickel, and the rest are a combination. Some meteorites also contain gold, copper, platinum, and carbon.
The moon is by far the biggest and most easily recognizable object in earth’s atmosphere that can be perceived by the naked eye on a cloudless night. It is hypothesized that it came into existence nearly 4.5 billion years ago, from residual debris after a planetary body collided with earth. Although, considered the runner-up to the sun as the second brightest object in the sky, its illumination is deceitful, insomuch as the moon is not a source of light, but instead reflects the sun’s illumination from the half of the moon that is in direct alignment with the sun at that time. More readily identified as a satellite of the earth rather than as a planet itself or even a star, it has a diameter a quarter of the size of earth’s size and it lacks an atmosphere, although date suggests a possibility that water may exist in the form of ice some embedded in craters near it’s North and South Pole. Similar to earth the moon posses a crust, mantle and core and is composed of comparable minerals such as oxygen, silicone, magnesium, aluminum, etc…
The moon is probably the most noticeable object outside of earth atmosphere besides the sun. There are a great number of facts about the moon. Most of these facts include size and distance of the moon compared to the Earth. Our moon's proper name is "Luna". Luna is 238,900 miles away from earth, and 27% smaller than earth. The moon is the most studied object outside of earths atmosphere. Luna is the only naturally made object that humans have set foot on besides earth.
Pluto is located 7.5 billion kilometers from Earth and is only over 2,000 km in diameter. Pluto has been labeled both a planet and a dwarf planet over the years. As said by USA Today, “a planet is a celestial body that: is in orbit around the sun, is round or nearly round, and has "cleared the neighborhood" around its orbit, meaning it is not surrounded by objects of similar size and characteristics.” Pluto only follows two of the three rules of a planet. Pluto crosses over Neptune’s orbit and is near other dwarf planets like it. Even though it breaks one rule it was officially named a dwarf planet in “August 2006”, as stated by the Library of Congress. After this event Pluto still only has one correct classification. Pluto is a planet because
In contrast, many icy bodies, such as Jupiter's moon Europa and Saturn's moon Enceladus, do not release large amounts of greenhouse gases via volcanoes. As such, researchers wanted to see how these worlds evolved if they had only the light of their stars to help warm
Introduction Both Sigmund Freud and Claude Levi - Strauss have had a significant influence on the interpretation of myths in anthropology. Although both of them base their interpretations upon the human mind their theories provide drastically different understandings of how myths are created and their purpose within cultures. These differences are primarily because they both believe the human mind to perform two different roles. To illustrate these two differing theories two Greek myths have been chosen. These are the “Castration of Uranus” and the “Defeat of Kronos.”
Our knowledge gained of Titan has drastically improved since the early 1980s when Voyager flew past it. Titan is Saturn’s largest moon and the second largest moon of our solar system. It has a diameter estimated roughly 40% of Earth’s moon (Titan’s Radius: 2576, Moon’s Radius: 1737) and is 80% more massive (Titan’s Mass: 1.35 x 10^23 kg, Moon’s Mass: 7.35 x 10^22 kg. Titan has a atmospheric surface pressure 50% more than of Earth’s. In addition to that, Titan is the only moon to have a dense atmosphere. Titan’s atmosphere has been calculated to be 4.5 times more dense than of Earth’s atmosphere, which can been clearly noted by the layers of haze seen. The atmosphere in Titan is approximately 1.5km and is mainly composed of nitrogen. Titan has a very similar vertical atmospheric structure to earth, Titan has a troposphere temperature of ~94-~70K, a tropopause temperature of 70.4K and a stratosphere temperature of ~70-175K.
Our solar system has eight planets, their moons and satellites, and they are all orbiting the Sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto used to be the ninth planet but IAU changed the definition of planet and Pluto did not meet the standards so it is now a Dwarf planet.
