However, when the radius became better known, ice alone was not enough. An outer layer of hydrogen and helium up to ten percent in mass would be needed on top of the ice to account for the observed planet radius. This prevents the need for an ice core. On the other hand, the planet may just be a…

Christopher Crokett in “Pluto: Explored” points out that the Planet Pluto has no control nor gravity. The description of Pluto is the diminutive ice-coated body and outlier. It always far above and well below the plane of the solar system. Moreover, Pluto once cross another planet’s like (Neptune’s) orbit.…
Pluto should not be a planet because Pluto should not be a planet because its a dwarf planet and what it takes to be a planet is to orbit around the sun, be spherical, and be the biggest thing in its orbit. Pluto is none of those. Pluto has fulfilled the first two rules to be a planet, but not the rest. Pluto is not the largest body in its orbit, but Eris (another dwarf planet.) is. Eris is 27% bigger than Pluto.…
Planet: (a) Orbits a star, (b) large enough for its own gravity to make it round, (c) has cleared most other objects from its orbital path.…
Pluto should not be considered a planet to me because it doesn’t have a cleared orbit. Pluto should stay a dwarf planet because it is the smallest planet in the solar system. Also Pluto’s moon is bigger than it therefore, is often mistaken as a double planet. Pluto shouldn’t be a part of the planets because according to the article “Why Pluto is no longer a Planet” by Fraser Cain the…

The distant, ice-covered world is no longer a true planet, according to a new definition of the term voted on by scientists today "Whoa! Pluto's dead," said astronomer Mike Brown, of the California Institute of Technology in Pasadena, as he watched a Webcast of the vote. "There are finally, officially, eight planets in the solar system." In a move that's already generating controversy and will force textbooks to be rewritten, Pluto will now be dubbed a dwarf planet. But it's no longer part of an exclusive club, since there are more than 40 of these dwarfs, including the large asteroid Ceres and 2003 UB313, nicknamed Xena—a distant object slightly larger than Pluto discovered by Brown last year. "We know of 44" dwarf planets so far, Brown said. "We will find hundreds. It's a very huge category." A clear majority of researchers voted for the new definition at a meeting of the International Astronomical Union (IAU) in Prague, in the Czech Republic. The IAU decides the official names of all celestial bodies. The tough decision comes after a multiyear search for a scientific definition of the word "planet." The term never had an official meaning before. What Is a Planet Today? According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit. Pluto has been demoted because it does not dominate its neighborhood. Charon, its large "moon," is only about half the size of Pluto, while all the true planets are far larger than their moons. In addition, bodies that dominate their neighborhoods, "sweep up" asteroids, comets, and other debris, clearing a path along their orbits. By contrast, Pluto's orbit is somewhat untidy. Astronomers estimate that there are at least 70,000 icy objects, with the samecomposition as Pluto, that measure…
Good morning ladies and gentlemen. Today you are here to decide whether the defendant presented is insane. This man was imprisoned for murdering his wife. This was after killing his first cat and aiming to kill his second. Why kill so many innocent lives? After hearing his significant story, many of you must be confused. You may believe he is indeed insane while others may think he pretending to be crazy in order to get out of his death penalty. My job here is to prove that he is faking it all. Therefore, he deserves to die for his horrible actions.…

The planet named after the famous Greek god of the sea is Neptune. Neptune is the eighth planet from the sun. It is dark, cold and whipped by supersonic winds. Neptune is a gas giant; it is made of the hydrogen and helium. The planet takes about 165 Earth years to orbit the sun. A day on Neptune is 16 hours and 6.7 minutes. Neptune orbits the sun at a distance of 30.1 AU. In 2011 it will complete its first orbit since its discovery in 1846. Neptune is the fourth-largest planet in diameter. Neptune is the third-largest planet in mass. The mass of this planet is 102,410,000,000,000,000,000,000,000 kg. Neptune is 17 times bigger than planet Earths. The largest moon Triton was discovered shortly after the planet was discovered. The interior of Neptune is like Uranus’s, which is composed of ices and rocks.…
In “The Pluto Files”, Neil Degrasse Tyson investigates Pluto’s current planetary status. Pluto was found to be much smaller in size than the rest of the planets, so much so that a conference was held with top scientists to debate if Pluto even qualified as a planet. One side of the public wanted Pluto to just “stay a planet”, as if calling it a planet still will change the fact that it’s not the same size and doesn’t have the same properties. Most others didn’t care. In “When Is a Planet not a Planet” by Freedman, Brian Marsden says "Pluto has been a longstanding myth that's difficult to kill,". While it did put up a fight, Pluto ended up being classified as a “dwarf planet”, which are actually being payed attention to now that Pluto is considered one. Even if everyone wanted Pluto to stay a planet, we have to classify it in a non-biased way based on a consensus of “what is a planet”, and unfortunately Pluto does not make the cut. The public opinion shouldn’t sway this case of classification as much as it did, as it needs to be supported by data and scientific facts, not mass support. If what we previously thought was right turns out to be wrong, we cannot just pretend like we never found out it was wrong. Sometimes changes must be made to what we know as we learn more, and lots of the time people aren’t ready for that change. Lying about Pluto or refusing to reclassify it won’t change the reality. Scientific classification needs to follow an agreed upon consensus, must be unbiased and truthful in what is reported, and cannot be released or changed to please the…
Neptune is the eighth and farthest planet from the Sun in the Solar System. Named for the Roman god of the sea, it is the fourth-largest planet by diameter and the third largest by mass. Neptune is 17 times the mass of Earth and is slightly 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. Its astronomical symbol is ♆, a stylized version of the god Neptune's trident.…
