...Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Neptune is 17 times the mass of Earth and is somewhat more massive than its near-twin Uranus, which is 15 times the mass of Earth but not as dense.[12] On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth–Sun distance. Named for the Roman god of the sea, its astronomical symbol is ♆, a stylised version of the god Neptune's trident. Neptune was the first planet found by mathematical prediction rather than by empirical observation. Unexpected changes in the orbit of Uranus ledAlexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed on 23 September 1846[1] by Johann Galle within a degree of the position predicted by Urbain Le Verrier, and its largest moon, Triton, was discovered shortly thereafter, though none of the planet's remaining 12 moons were located telescopically until the 20th century. Neptune has been visited by only one spacecraft, Voyager 2, which flew by the planet on 25 August 1989. Neptune is similar in composition to Uranus, and both have compositions which differ from those of the larger gas giants, Jupiter and Saturn. Neptune's atmosphere, while similar to Jupiter's and Saturn's in that it is composed primarily of hydrogen and helium, along with traces ofhydrocarbons and possibly nitrogen, contains...

...Abstract Neptune Gourmet Seafood is facing a problem with oversupply for existing demand. It can either decrease supply to match demand or increase demand to match supply. I recommend the latter. I further recommend the way to increase demand is for Neptune to increase its marketing efforts in its existing markets and to penetrate other markets it currently is not in. The Competitive Environment Neptune is a 40-year-old, $820,000,000 company, specializing in quality shell and non-shell seafood in a $20 million industry. It is North America¡¦s third-largest seafood producer, but that designation is misleading, because its revenues account for only 4.1% of the total market. As such it is but one of many firms operating in the seafood processing industry, one whose market structure could be termed monopolistic competition. The industry is not limited to North American firms such as Neptune, but also includes companies from China, Peru, Chile, and Japan, competition from which has pushed Neptune to upgrade its fishing fleet and which also has helped shrink the company¡¦s margins by 10%.. Neptune markets to the high end of the market, differentiating itself from the competition by its quality, selling its high-end brand at 25-30% above the rest of the market. Their years of ex perience coupled with the company¡¦s value development pose a threat to any new firm trying to enter the market. It is the only member company of the U.S. Association of Seafood Processors and Distributors...

...What is the Solar System? The Solar System is a stellar system made up of the Sun and the planetary system that orbits it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies such as comets and asteroids. *The Planets of the Solar system and their name meanings Mercury- the messenger god Venus- god of love Earth- is the son of Gaia goddess of universe Mars- god of war Jupiter- god of lightning Saturn- god of agriculture Uranus- god of light Neptune- god of the sea Pluto- god of death Mercury is the smallest and closest to the Sun of the eight planets in the Solar System, with an orbital period of about 88 Earth days. Seen from Earth, it appears to move around its orbit in about 116 days, which is much faster than any other planet in the Solar System. It has no known natural satellites. The planet is named after the Roman deity Mercury, the messenger to the gods. Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. It has no natural satellite. It is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of −4.6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun. Earth is the third planet from the Sun, the...

...Planetary comparison Chris Bond SCI 151 11/30/10 Norm Stradleigh The make-up of the solar system consists of eight planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, and two dwarf planets: Pluto and Eris. These planets all revolve around an average-sized star in which we call our sun. Before we begin comparing the planets within our solar system we must first ask ourselves what a planet is. First to be called a planet, the body must have its own orbit around the Sun, It should be spherical by the merit of its own gravitational force, and it should be the biggest, most gravitationally dominant object in its own orbit. Now that this has been explained, planets are broken up into two different types: celestial and Jovian. Celestial planets within our solar system include Mercury, Venus, Earth, and Mars, and the Jovian planets are made up of Jupiter, Saturn, Uranus, and Neptune. The key difference between these two types of planets is simple: Celestial planets are made of rocky and metallic substances, which give it a surface, whereas Jovian planets or gas giants are primarily made up of large amounts of hydrogen and helium gases. The celestial planets formed within the warmer zone of the solar system with all the hard physical matter combining over billions of years to form planets. This explains their relative size as compared to...

...was elected as Rector. Rector meant ruler. At Breslau he dealt with the exact determination of planetary orbits and developed methods for calculating the height of the aurorae and the path of meteors, and consolidated the data for all 414 comets discovered up to 1894 into one work {with help from his son}. Otherwise he concerned himself with the Earth’s magnetic field and climatology. Altogether he published 200 works. An aurora was a natural light in the sky. Later years In 1897 Galle returned to Potsdam, where he died at the age 98. He was survived by his wife and two sons-Andres Galle and Georg Galle {1850-1946}. Two craters, one on the moon and the “happy face” on mars, the asteroid 2097 Galle a Ring of Neptune have been named in his honor.

...Uranus is the seventh planet from the Sun. It has the third-biggest planetary range and fourth-biggest planetary mass in the Solar System. Uranus is comparative in piece to Neptune, and both have distinctive mass synthetic creation from that of the bigger gas titans Jupiter and Saturn. Hence, researchers regularly characterize Uranus and Neptune as "ice monsters" to recognize them from the gas goliaths. Uranus' climate, albeit like Jupiter's and Saturn's in its essential creation of hydrogen and helium, contains more "frosts, for example, water, smelling salts, and methane, alongside hints of different hydrocarbons. It is the coldest planetary air in the Solar System, with a base temperature of 49 K (−224.2 Celsius), and has a perplexing, layered...

...Ty Gilbertson 828811509 MU100 Ellins 2PM Assignment #2 Holst: The Planets Before listening to “The Planets” play list I was somewhat skeptical on how accurately Holst would portray each individual planet in music form. After listening to the songs I was impressed by how the artist personified each planet giving every planet a different tempo, instrument combination, and rhythm. My favorite songs were Mars and Mercury because Mars has faster tempo with strong horn and percussion sections and Mercury has an uplifting pace and pleasant string instruments. When I started listening to Mars I visualized an inter-galactic battle taking place with the song playing in the background. I didn't like Venus or Saturn all that well because of the somber tone and the slow pace didn't hold my attention as well. Overall I enjoyed The Planets play list and the artist did an excellent job representing all the planets in musical form. Beyond the Score Video In addition to the Holst the Planets play list, the Beyond the Score video, directed by Gerald McBurney, featuring Simon McBurney, performed by the Chicago Symphony Orchestra, and conducted by Charles Dutoit, offers viewers a deeper more historical perspective on the musical piece. The video begins with a detailed look at Mars: The Bringer of War and how the uses of horns and trumpets have been used for thousands of years to frighten opposing armies before battle. In particular, the use of the bass oboe gives the musical piece the recognizable...

...as extrasolar planets. The solar system has been relatively well-studied, initially through telescopes and then later by spacecraft. This has provided a good overall understanding of the formation and evolution of this planetary system, although many new discoveries are still being made.[50] The black spot at the top is a dust devil climbing a crater wall on Mars. This moving, swirling column of Martian atmosphere (comparable to a terrestrial tornado) created the long, dark streak. NASA image. The solar system is subdivided into the inner planets, the asteroid belt, and the outer planets. The inner terrestrial planets consist of Mercury, Venus, Earth, and Mars. The outer gas giant planets are Jupiter, Saturn, Uranus, and Neptune.[51] Beyond Neptune lies the Kuiper Belt, and finally the Oort Cloud, which may extend as far as a light-year. The planets were formed in the protoplanetary disk that surrounded the early Sun. Through a process that included gravitational attraction, collision, and accretion, the disk formed clumps of matter that, with time, became protoplanets. The radiation pressure of the solar wind then expelled most of the unaccreted matter, and only those planets with sufficient mass retained their gaseous atmosphere. The planets continued to sweep up, or eject, the remaining matter during a period of intense bombardment, evidenced by the many impact craters on the Moon. During this period, some of the protoplanets may have collided, the leading hypothesis...

...PLANETS By Reanna Hinson The purpose of my project and essay is to familiarize ourselves with the different planets within our own solar system. I will present different, unique and amazing facts about each the eight planets. My project also displays a colored example of what each planet appears to look like as well as statistical information. Mercury, Venus, Earth, and Mars, are called the terrestrial planets because they have solid rocky surfaces. Jupiter, Saturn, Uranus, and Neptune and are called gas giants. Earth is the only planet of the eight that has life forms as we know them. All other planets have extreme conditions such as temperatures, atmospheres and weather that make life as we know it impossible to exist, but we still keep looking for alien signs of life. Mercury Mercury is a small planet that spins very slowly in orbit around the sun. It is the planet closest to the sun and has extreme temperature changes. During the day the temperature can soar to 870° Fahrenheit and at night time down to -300° Fahrenheit. Mercury has no moons and a very small and weak atmosphere because the Sun’s solar winds have blown it away. This causes very little to no air on Mercury. Venus Venus and Earth are just about the same size, but Venus always has a thick cloud cover making it impossible to see the surface of the planet, and traps a lot of the Sun’s heat making it the hottest average temperature of all the planets. The average temperature is 850° Fahrenheit...

...people often wonder how and why a an hour consists of 60 minutes and a day is divided into 24 hours. We can all tell time and we schedule our appointments and dates around time and day all the time. No one ever really stops to look into the history of the origin of time and how it was determined to be divided upon. However, that definition is a narrow one that only applies to planet earth., but what about other planets? One day is the length of time it takes for a planet to complete one single rotation on its axis which is 360°. Since all of the planets rotate at different speeds, the length of a day on each one differs. The definition of a day will explain just how many hours are in a day for Earth, Venus, Mars, Jupiter, Saturn, Uranus , Neptune, Mercury and Pluto. Explanation of the units of an hour and day There is documented evidence of the use of sundials that were used by Egyptians as early as 1500 B.C.. Sundials were stakes that were strategically placed in the ground so that they can indicate the time by the length and direction of the resulting shadow. A duodecimal system was used to divide the time period between sunrise and sunset into 12 parts. The number 12 was significant because it is the number of lunar cycles in a year. The night sky was divided by 12 and a circle into 360 degrees. They divided the day and night each into 12 hours. The hour was split into 60 minutes and a minute into 60 seconds. The Egyptians divided the clock into 12 hours of daytime and...

...desire and curiosity that arose, the desire to know what is there beyond earth. This desire arose from people wanting to know whether there exists another world other than the current one we live in, and whether there is life there in space. The discovery of the planet Uranus in the year 1781 by Sir William Herschel, planet Neptune in the year 1846 by John Couch Adams and Pluto by astronomer Clyde Tombaugh in the last century is among the notable discoveries. As a result, governments have invested resources that would be channeled towards space exploration. In October 1957, the first artificial satellite, Sputnik 1, was launched into space. Later on after four years in April 1961, Russian Lt. Yuri Gagarin orbited the earth. Since then, a series of other space visits occurred aimed at studying beyond earth, the contents and properties. Thus the discovery of planets continued. One of the planets in existence was planet Saturn. It is the sixth planet from the sun. It is also the second largest planet. Here are some 10 important facts about this planet Saturn 1. Saturn is Surrounded by a ring Saturn is one of the planets, apart from Jupiter, Uranus and Neptune planet in the solar system that is surrounded by a large, beautiful and extensive ring. Its ring is the biggest and brightest. It has thus been nicknamed famously as “The Ringed Planet”. These are actually many tiny rings called ringlets that make up the larger ring. An astronomer called Galileo was the first person to see...

...seventy-sixth birthday, the IAU relegated Pluto to the status of a dwarf planet (Long, par. 7). After fiery debates, explosive arguments, and crucial questions, the IAU announced they would be holding a conference.In 2006, over 2500 scientists attended the conference to discuss Pluto and its geological features (Long, par. 1). This conference ultimately was the demise of Pluto as a planet. While discussing its major discoveries, NASA learned that Pluto does not fit in either gaseous or rocky planets, as the other eight do. Pluto’s composition is ice (Cowen, par. 3). No life, not even bacteria, could form on the frozen pieces of Pluto. Not only was Pluto icy, but it was significantly smaller than the moons of four other planets: Saturn, Jupiter, Neptune, and Earth (“Forbidden Planet,” par. 8). Pluto’s size is approximately 2300 km in diameter which is larger than most dwarf planets (“Forbidden Planet,” par. 8). However, Pluto’s problem was because of its size. Being able to see Pluto, scientists decided they would keep looking as far as they could. With this idea came the discovery of UB313, also known as Xena. Xena is farther than Pluto and is slightly larger. Xena’s diameter measures 2400 km (“Forbidden Planet,” par. 3). If by definition Pluto was a planet, then Xena and 200 others would be as well (Long, par. 1), causing controversy amongst the IAU and the public about the definition of a planet. Pluto, small in diameter and made of ice, has a gravitational pull of less than 6% of...
