The Dwarf Planet Sedna Discovery and Facts

Way past the orbit of Pluto, theres an object orbiting the Sun in a highly eccentric orbit. The objects name is Sedna and its probably a dwarf planet. Heres what we know about Sedna so far. Facts Facts: Sedna MPC Designation: Formerly 2003 VB12, officially 90377 SednaDiscovery Date: November 13, 2003Category: trans-Neptunian object, sednoid, possibly a dwarf planetAphelion: about 936 AU or  1.4Ãâ€"1011  kmPerihelion: 76.09 AU or  1.1423Ãâ€"1010  kmEccentricity:  0.854Orbital Period: about 11,400 yearsDimensions: estimates range from about 995 km (thermophysical model) to 1060 km (standard thermal model)Albedo: 0.32Apparent Magnitude: 21.1 The Discovery of Sedna Sedna was co-discovered on November 14, 2003 by Michael E. Brown (Caltech), Chad Trujillo (Gemini Observatory), and David Rabinowitz (Yale). Brown was also a co-discoverer of the dwarf planets Eris, Haumea, and Makemake. The team announced the name Sedna before the object had been numbered, which was not proper protocol for the International Astronomical Union (IAU), but didnt raise objections. The worlds name honors Sedna, the Inuit sea goddess who lives at the bottom of the icy Arctic Ocean. Like the goddess, the celestial body is very far away and very cold. Is Sedna a Dwarf Planet? Its likely Sedna is a dwarf planet, but uncertain, because its so far away and hard to measure. In order to qualify as a dwarf planet, a body must have enough gravity (mass) to assume a rounded shape and may not be a satellite of another body. While the plotted orbit of Sedna indicates its not a moon, the worlds shape is unclear. What We Know About Sedna Sedna is very, very distant! Because its between 11 and 13 billion kilometers away, its surface features are a mystery. Scientists do know its red, much like Mars. A few other distant objects share this distinctive color, which could mean they share a similar origin. The extreme distance of the world means if you viewed the Sun from Sedna, you could blot if out with a pin. However, that pinprick of light would be bright, about 100 times brighter than the full moon viewed from Earth. To put this into perspective, the Sun from Earth is around 400,000 times brighter than the Moon. The size of the world is estimated to be about 1000 kilometers, which makes it about half the diameter of  Pluto (2250 km) or around same size as Plutos moon, Charon. Originally, Sedna was believed to be much larger. Its likely the size of the object will be revised again as more is known. Sedna is located in the Oort Cloud, a region containing many icy objects and the theoretical source of many comets. It takes a long time for Sedna to orbit the Sun—longer than any other known object in the solar system. Its 11000 year cycle is so long partially because its so far out, but also because the orbit is highly elliptical rather than round. Usually, oblong orbits are due to a close encounter with another body. If an object either impacted Sedna or drew close enough to affect its orbit, its no longer there. Likely candidates for such an encounter include a single passing star, an unseen planet out beyond the Kuiper belt, or a young star that was with the Sun in a stellar cluster when it formed. Another reason a year on Sedna is so long is because the body moves relatively slowly around the Sun, about 4% as fast as the Earth moves. While the present orbit is eccentric, astronomers believe Sedna likely formed with a near-circular orbit that was disrupted at some point. The round orbit would have been necessary for particles to clump together or accrete to form a rounded world. Sedna has no known moons. This makes it the largest trans-Neptunian object orbiting the Sun that doesnt have its own satellite. Speculations About Sedna Based on its color, Trujillo and his team suspect Sedna may be coated with tholin or hydrocarbons formed from solar irradiation of simpler compounds, like ethane or methane. The uniform color could indicate Sedna doesnt get bombarded with meteors very often. Spectral analysis indicates the presence of methane, water, and nitrogen ices. The presence of water could mean Sedna had a thin atmosphere. Trujillos model of the surface composition suggests Sedna is coated with 33% methane, 26% methanol, 24% tholins, 10% nitrogen, and 7% amorphous carbon. How cold is Sedna? Estimates place a hot day at  35.6  K (−237.6  Ã‚ °C). While methane snow may fall on Pluto and Triton, its too cold for organic snow on Sedna. However, if radioactive decay heats the interior of the object, Sedna could have a subsurface ocean of liquid water. Sources Malhotra, Renu; Volk, Kathryn; Wang, Xianyu (2016).

Sociological Reflection - 938 Words

Sociology has guided me into having a better understanding and concept of the relationship between myself and society. Within time my knowledge in sociology has grown and I now perceive life differently with some of the things I have learned throughout the course. A lot of the sociological concepts that I have learned have impacted my way of thinking in a positive manner. Every new unit that we are taught is an eye opener for me because of how enlightened I have become from viewing myself and society by more of an open mind. Concepts that have been an eye opener to me since the previous section reflection include blah, the different types of social classes, and lastly culture appropriation. Each of these three topics is only a minor part†¦show more content†¦I am very aware of all the different cultures that there are but what I was not aware of was how some races feel about how others identify their culture as. Culture appropriation has opened my eyes and made me aware of h ow others â€Å"adopt† elements from one’s culture and include it in their own personal life. This may come off very offensive to others when we see their culture being worn or acted on someone who is not of that culture. I recently have seen it most during the most recent holiday that just came up, Halloween. When others dress up and make their costume crafted from other’s culture. This concept has strengthened my understanding of culture appropriation by being more aware of how society acts upon culture appropriation and if I ever (for whatever the reason may be) tend to show this type of appropriation to know what I may be wearing, saying, or acting can be offensive to others which can make me just insensitive. Even if it is not clear at times it is always good to educate yourself on these matters to not let it happen in the future. One of the last concepts in the past few units that has spoken out to come comes from chapter 9, â€Å"Constructing Gender and Sexuality†. I have always been an open minded person, I am not one to discriminate. I have always been open to learning new things and the idea of sexuality as whole.

Essay Question An Inspector Calls Example For Students

Essay Question An Inspector Calls Produce an empathic response to character and themes in An Inspector Calls basing your response on role-play activities, which demonstrates your understanding of the historical, cultural and social contexts in the play.  An Inspector Calls was written post- World War Two around 1945. It is set in 1912, just before World War One started.  In the stage production, the play is introduced with some 1940s dressed children entering the play from a hatch in the visible part of the stage. The stage is strangely curled downwards towards the left of the stage, and a telephone box with smashed windows is leaning inwards towards it. There is a 1940s radio on the right, which a young boy kicks until is begins churning out wartime music. A siren begins ringing, the children run underneath the curtain and the curtain lifts. On stage is a house on a street, with a street lamp and a smaller version of the house towards the back of the stage. The sky is dark and cloudy, and it is raining. An old woman, Edna the maid, sits near the house on a small chair. The family sit inside the house.  The Inspector first enters the play from the auditorium in a ghostly and sinister way and is almost on the stage before the audience register his presence. He enters almost as if he has come from elsewhere, in an eerie and almost Christ-like way. He hands the boy an orange and the boy runs off. This may signify the irony that the play was written in the mid 1940s (WW2) and set in 1912(WW1), and the scarcity of oranges at both of these times. The family are sat in the small house, eating and drinking merrily. The family are having a celebratory dinner due to Sheila Birlings engagement to Gerald Croft. The Inspector makes his presence known and speaks to Arthur Birling first, informing him of a young girls successful suicide attempt.  Id like some information, if you dont mind, Mr Birling. Two hours ago a young woman died in the Infirmary. Shed been taken there this afternoon because shes swallowed a lot of strong disinfectant.  The Inspector shows Arthur a photograph, and Arthur remembers the victim, one of his ex-employees, Eva Smith. Arthur sacked her, as she wanted a pay rise. They wanted the rates raised so they could average twenty-five shillings a week. I refused, of course. This passage shows how Arthur has a greedy and selfish side, greed being one of the main themes in the play. Sheila is next to be interrogated by the Inspector. The Inspector tells her that after she got sacked by Mr Birling, Eva went for a job at Milwards, one of Sheilas favourite clothes shops. She was taken on in a shop-and a good shop too- Milwards. He shows Shelia a photograph of Eva and she sobs. Sheila lost Eva her job at Milwards which helped lead to the suicide. I caught sight of her smiling at the assistant, and I was furious with her. I went to the manager at Milwards and I told him that if they didnt get rid of that girl, Id never go near the place again and Id persuade Mother to close our account with them. Eva was discharged immediately. These passages show how Sheila was greedy and made Milwards discard Eva Smith in order to keep her account. It shows how Sheila was jealous and greedy. The Inspector next talks to Sheilas fianc Gerald Croft. Eva Smith apparently changed her name to Daisy Renton, and this name Gerald recognises. Now she had to try something else. So first she changed her name to Daisy Renton.   What? exclaims Gerald. It turns out Gerald had an affair with Eva, which lasted many months until they broke up in the first week of September. Eva supposedly took it very well but this event still helped towards her suicide. .ue68bcd8faeafe585320105dd82a65f82 , .ue68bcd8faeafe585320105dd82a65f82 .postImageUrl , .ue68bcd8faeafe585320105dd82a65f82 .centered-text-area { min-height: 80px; position: relative; } .ue68bcd8faeafe585320105dd82a65f82 , .ue68bcd8faeafe585320105dd82a65f82:hover , .ue68bcd8faeafe585320105dd82a65f82:visited , .ue68bcd8faeafe585320105dd82a65f82:active { border:0!important; } .ue68bcd8faeafe585320105dd82a65f82 .clearfix:after { content: ""; display: table; clear: both; } .ue68bcd8faeafe585320105dd82a65f82 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue68bcd8faeafe585320105dd82a65f82:active , .ue68bcd8faeafe585320105dd82a65f82:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue68bcd8faeafe585320105dd82a65f82 .centered-text-area { width: 100%; position: relative ; } .ue68bcd8faeafe585320105dd82a65f82 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue68bcd8faeafe585320105dd82a65f82 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue68bcd8faeafe585320105dd82a65f82 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue68bcd8faeafe585320105dd82a65f82:hover .ctaButton { background-color: #34495E!important; } .ue68bcd8faeafe585320105dd82a65f82 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue68bcd8faeafe585320105dd82a65f82 .ue68bcd8faeafe585320105dd82a65f82-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue68bcd8faeafe585320105dd82a65f82:after { content: ""; display: block; clear: both; } READ: Dickens portrait of England EssayAfter Gerald left her, Eva went to Sybil Birlings Womens Organization to seek help. At first she called herself Mrs Birling, much to Sybils disgust, and later told lies to the committee. They eventually turned her away. Sybil was greedy and refused to help Eva, leaving her on the streets and even more depressed. The Inspector uncovers that Eva was pregnant when she went for refuge at Sybils hostel, and the father was Eric. Eric comes back to the family and admits all. I wasnt in love with her or anything-but I liked her. She told me she was going to have a baby. Eric also admits he stole money to support her I got it-from the office-. Eric was greedy when he stole the money and when he did not stand by Eva.  Greed plays a major role in the play, as it is the root of all of the Birlings mistakes and is categorised as one of the plays many themes, along with responsibility, good and evil, and collective responsibility. Eva Smith is seen as a generic character, representing all such people from her social class and especially women in her position, for instance oppressed workers, or women into prostitution. There are many Eva Smiths. There are also parallels between Eva and the Everyman character from an early 16th century morality play. This character personifies dispute between good and evil- themes in An Inspector Calls. She also has parallels with Eve from the Bible- greed was the original sin from the beginning of time and was the beginning of Evas problems.  Eric, particularly, is not very responsible when he becomes the father of Evas baby, and with his drinking habits. He steals money from his father, which shows extreme measures of irresponsibility. When Gerald goes with Eva he is acting irresponsibly as he is due to marry Sheila. Another key theme in An Inspector Calls is collective responsibility.
