Planet Pluto

Length: 3 Pages 627 Words

PLUTO My topic is the planet Pluto. I chose this planet because a lot of people don’t even consider it a planet. The earth’s moon is even bigger than Pluto. Other than that I don’t really know anything at all about the planet. I did also know that Pluto does intertwine with Neptune’s orbit. Is Pluto really a planet? Researchers have been trying to determine whether Pluto is really big enough to be a planet. Over the last few years, the gathered information on Pluto and the discovery of an increasing number of other objects in the outer solar system have been discussed within a group of astronomers called minor-planets. The planet Pluto is not given the respect of other planets and some have the indication to change Pluto to a minor planet. Astronomer Brian Marsden of Harvard Smithsonian Center said if Pluto were discovered seventy years ago, it would be considered a minor planet. A mino Continue...

Some astronomers do not agree with Brian Marsden's theory. Pluto deserves to be considered more than just a minor planet. It was estimated that Pluto contained mass of eleven Earths but dropped rapidly over time. Studies conducted using a spectroscope have detected methane frost on Pluto and water frost on Charon. Nicholson calls the Pluto debate a "'Tempest in a teapot' with little effect on the course of solar-system research. Does this mean Pluto has been demoted The answer is no. It is known to have density of two grams per cubic centimeter, so is estimated to be sixty percent rock and forty percent ices of frozen nitrogen, carbon monoxide, methane, and water. r planet is a term used to describe asteroids and most astronomers agree that Pluto is no asteroid. Pluto has one moon, Charon, which is half the size of Pluto. Marsden said it's not a demotion for Pluto to be referred to as the 10,000th minor planet, it is an honor. Because of the shape of Pluto's orbit, it actually slips inside of Neptune's orbit once every 248 Earth years for a period of twenty years. And while other 'major planets' have roughly circular orbits, Pluto carves out a sweeping ellipse that frequently takes it closer than Neptune to the sun. Pluto, the planet farthest from the sun, is smaller than Earth's moon.
