The New Planet X Analysis - 774 Words

The New Planet X For centuries, researchers have been looking for more planets in our solar system, with more public focus on the matter in the past decade after Pluto’s reclassification to â€Å"dwarf planet†. At last, astronomers have found a possible expansion to our local solar system, or at least this is what the Science News article â€Å"Shadow Planet†, written by astronomer Christopher Crockett, implies. In this article Crockett summarizes the history of the idea of a â€Å"Planet X† in our solar system, providing the necessary background to understand the rest of the article, where he discusses evidence that heavily supports the idea of a new planet far in our outer solar system. The article’s author, Cristopher Crockett, is a writer for Science News magazine, and a previous writer for Scientific American. Crockett is also a former researcher from the U.S. Naval Observatory, focusing on the exploration of planets in our outer solar system, with a Ph.D in astronomy. He left his career as a researcher to pursue writing in 2013, after being awarded the 2013 Mass Media fellowship from the American Association for the Advancement of Science (AAAS) to write for Scientific American. Crockett shows expertise in all areas of astronomy, writing articles on a wide variety of astronomical topics, from explanations of the gravitational waves caused by black holes to discussions about newly discovered exoplanets. In the article, Crockett starts by mentioning the primary evidence for a notShow MoreRelatedThe sun is a star in which all of the planets of the solar system orbit around. The sun involves700 Words   |  3 PagesThe sun is a star in which all of the planets of the solar system orbit around. The sun involves three key parts consisting of the core which makes up 25 percent of the sun, the radiative zone which makes up 45 percent of the sun, and the convective zone which makes up 30 percent of the sun. The sun contains a large amount of hydrogen in its core which is where most of the nuclear reactions take place. At the sun’s core, gravity attracts all of the mass inward and generates a pressure large enoughRead MorePluto s Position On The Solar System1426 Words   |  6 PagesIntroduction – Pluto’s Position in the Solar System Pluto used to be considered the ninth planet of our solar system, but in 2006 Pluto s planetary classification was changed to a dwarf planet (Choi). Pluto is located in the Kuiper belt and it orbits beyond Neptune, which makes Pluto a trans-Neptunian object, or TNO (Schneider and Arny 380-381). Pluto’s elliptical orbit of the sun takes 248 years, and on average it is approximately 3.6 billion miles from the sun (Dunbar). Pluto has an extremelyRead MoreGalileo s Observation Of Astronomy1018 Words   |  5 Pagesallow us to observe other wavelengths such as gamma rays, x-rays, ultraviolet and infrared. They are also unaffected by weather, daylight, and light pollution. Another advantage of space telescopes is that they can provide sharper images because they are unaffected by atmospheric turbulence which can blur the images of ground-based telescopes (a phenomenon known as ‘seeing’). As of 2006 the International Astronomical Union defines a planet as a celestial body that: 1. Is orbiting the Sun 2. Has aRead MoreEssay about Intelligent Extraterrestrial Life936 Words   |  4 PagesIntelligent Extraterrestrial Life When I look up at the stars at night, I just have to wonder who or what is looking back at me from some distant planet in some distant galaxy. We’ve all probably wondered what lies beyond our small, self-contained little world. The question many have pondered is whether or not there is intelligent life beyond earth.
