Add a tenth planet to the solar system -- or possibly subtract one.
Astronomers announced yesterday that they had found a lump of rock and ice that was larger than Pluto and the farthest known object in the solar system. The discovery will probably rekindle debate over the definition of ''planet'' and whether Pluto still merits the designation.
The new object -- as yet unnamed, but temporarily known as 2003 UB313 -- is now 9 billion miles away from the Sun, or 97 times as far away as Earth and about three times Pluto's current distance from the Sun. Its 560-year elliptical orbit brings it as close as 3.3 billion miles. Pluto's orbit ranges from 2.7 billion miles to 4.6 billion.
The astronomers do not have an exact size for the new planet, but its brightness and distance tell them that it is larger than Pluto, the smallest of the nine known planets.
''It is guaranteed bigger than Pluto,'' said Michael E. Brown, a professor of planetary astronomy at the California Institute of Technology and a member of the team that made the discovery. ''Even if it were 100 percent reflective, it would be larger than Pluto. It can't be more than 100 percent reflective.''
The discovery was made Jan. 8 at Palomar Observatory in California. Dr. Brown and the other members of the team -- Chadwick A. Trujillo of the Gemini Observatory in Hawaii and David L. Rabinowitz of Yale University -- then found that they had, unknowingly, taken images of the planet, using the observatory's 48-inch telescope, as far back as 2003.
Last year, the same team announced the discovery of a distant body they named Sedna, which, until the latest discovery, had held the title of farthest known object in the solar system. But Sedna, smaller than Pluto, is on a far stranger, 10,500-year orbit that takes it as far out as 84 billion miles.

The planets show their behaviour according to the house they occupy. This lesson describes the method to calculate the dimensions of the house and thus determine in which house the planet lies. It also describes the Western or K P Method of house division. By now we have learnt how to c alculate ascendant, tenth house and planets' position…
gases into our atmosphere. The alternative to exhausting these fossil fuels is to tap into sources of renewable energy. Solar, wind, hydropower, geothermal and biomass are all sources of renewable energy that is clean and far less destructible to our planet. There are opposing views as to whether the benefits of renewable energy outweigh the hazards of depleting fossil fuels. Many people believe that is at least partially attributed to the effect of the use of fossil fuels. The use of coal to produce…
markets are the world’s leader in natural and organic foods with stores in North America and United Kingdom .Their mission is Whole Foods-Whole People- Whole Planet. Whole Food stands for searching for the highest quality and natural foods possible. Whole People mean that the people their hire are passionate about healthy food. Whole Planet means they are committed to helping take care of the world around us. McGregor’s Theory Y is one of the two theories contrasting assumptions about human nature…

was born in 19th century invented the idea of establishing the London underground (Wolmar, 2004, P. 23) . “The first underground railway in the world started with opening of the Metropolitan Railway between Bishops Road, Paddington and Farringdon on 10th January 1863” (Tubeprune, par. 1). On the other hand, the Tokyo subway system has a shorter history. The subway system in Tokyo started to work in 1927; at that time, there was just one private subway line from Asakusa to Ueno, and expanded to Shibuya…
influence to all parts of the world.” Knowing that an influence can be good or bad, in the case of business globalization the control would not be enough, i.e. detrimental to humans and wildlife. (2 conclusion) Globalization can only be good for a planet if the ones in charge are responsible. Only if the ones in charge of the global business create laws that are good and treat people fairly can it ever work. In many occasions though, people are mistreated and are forced into the belief systems of…
truth of the matter is that green technology may not have a history, but it surely has a very extensive past. It has been reported that early missionaries documented the Chinese using coal as an energy source as far back as 2000 B.C. and during the 10th Century the Persians used windmills to grind their harvested grain and pumped water from rivers and streams. This usage later continued its development which eventually spread other versions of the windmill to parts of India, China and the Muslim world…
Volcanoes are deadly landforms, when they eject molten rock and ashes it can have devastating consequences. Volcanoes are also important to our planet’s history and they are necessary to life on earth. While useful, the planet has a history of deadly eruptions and we still are at risk. In the United States, we have a super volcano that could erupt and change earth for years or decades. Scientists have ways to predict possible eruptions, but not every circumstance is able to be monitored. A volcano…
access content freely and without corporation censoring the content or slowing down the connection speeds, and because so much of the world’s internet traffic passes through the United States, any regulations to the internet will impact the entire planet. (Goodman, 2014) The fact that a provider could block or slow down a competitor’s site or a site with differing views is too much power and nobody should be allowed to do it. I like my internet free and open. There are a lot of companies that feel…
President in 2009. He stated that, “America has witnessed an unconscionable abuse of power.” Romney was supporting to repeal this bill, stating in December 2011, “If I’m President, we’re going to get rid of Obama Care and return, under Constitution—the 10th Amendment—the responsibility of health care to the people in the states.” (Ajherrha-mittromney) What Romney sounds like he is stating here is that people in the states are responsible for paying full medical care bills, instead of getting help from…
