February 21‚ 2013 Where do planets come from? Abstract Astronomers have spent many centuries wondering how our solar system and its planets came to be. We could only see the end result of planet formation‚ not the process itself. And we had no other examples to study. Even with the knowledge gained about other solar system‚ we were left to wonder‚ are there other planetary systems out there‚ and did they form like ours? This project leads you to find out how mighty planets are formed from cosmic dust

Ever since grade school you were taught that our solar system has nine planets. Sadly that is no longer the case; in 2006 astronomers have decided that Pluto no longer qualifies as a planet. Pluto is now considered a “Dwarf Planet” and has caused a lot of controversy among astronomers. A dwarf planet is not even considered to be a planet‚ and there are projected to be hundreds of them in our galaxy. Pluto is being demoted to what amounts as a third class citizen in our galaxy. Thousands of textbooks

Why Pluto should stay a planet You may think that Pluto is all alone and the only lonely planet. He is really not left out. There are more Dwarf planets out there. Pluto is not alone! So don’t make it seem like Pluto is all alone‚ because it is not! Besides‚ Pluto there are four other known dwarf planets. Eris‚ Ceres‚ Makemake‚ and Haumea. The latter three of which are in the Kuiper Belt. Dwarf planets are worlds that are too small to be considered developed planets‚ but also too large to be put

researching and coming together on whether the planet Pluto should be considered a “dwarf planet” or a part of the regular planets. Pluto was discovered in 1930 by Clyde W. Tombaugh. Astronomers believed that Pluto was to be considered a planet. Soon they concluded that their evidence didn’t support their reasoning. 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

Alien Planet Kepler-452b Our Milky Way Galaxy is filled with exoplanets—statistically speaking at least one for each of the hundreds of billions of stars in the galaxy. An astonishing finding is that the most common type of planet in our galaxy are those with sizes between those of Earth and Neptune. This has become a new class of planet that is neither terrestrial nor giant and one without an accepted theory for its formation. Planets on orbits between the hot planets and the cold planets are also

Pluto is not a planet For my whole life I have been taught that there were exactly 9 planets in the solar system. I had learnt this at a very young age and the number 9 had often been stressed to me. I can’t believe the amount of tests that I had failed on the subject because I had failed to remember one of these planets. My excuse had always been‚ "No! That’s not a planet!". If I had forgotten Saturn then I would say‚ " Oh sir! Saturn’s not really a planet‚ it’s yellow and everyone knows that

Is Our Atmosphere Unique? The planet Jupiter has the biggest atmosphere in our solar system. Jupiter’s atmosphere is composed of 90% hydrogen and 9.9% helium and .1% other gases such as sulfur‚ methane‚ ammonia‚ and water vapor. It is able to hold its atmosphere in because of its massive gravitational pull that is around 2.5 times stronger than earth’s pull. To put that into perspective‚ if you weigh 100 pounds on earth you would weigh 250 pounds on Jupiter. The atmospheric layers are the

THE PLANET MARS AND ITS INHABITANTS ESSAY: The Urides God Theory Eros Urides paints a very detailed picture of endless imagination in his short science fiction epic‚ “The Planet Mars and its Inhabitants‚” written in the 1920’s. Urides does this by creating a complex yet believable story line of how life on Mars could be in comparison to our planet Earth. Outlining key details‚ which we will cover in this essay‚ Urides explains to us
