Galileo and Copernicus were two extremely influential astronomers. They believed in the heliocentric model of our solar system‚ or the idea that the planets revolved around the Sun. We all accept this model today as fact‚ but back in their time‚ the thought of it was pure blasphemy. The widely accepted idea at the time‚ as supported by the almighty Catholic Church‚ was the geocentric model. In this model‚ the Earth is central to nearly everything‚ and is orbited by the Sun‚ moon‚ and other special

In the following report I focus on astrobiology as it applies to geology‚ or what kinds of planets‚ stars and solar systems are the most likely to play host to life in some form or another. Basic Assumptions Earth is the only planet in the universe we know supports life and the life indigenous to Earth is the only life we know of in the universe. Although it is possible‚ and in fact likely when considering

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

“Goldilocks and the Three Planets” “Goldilocks and the Three Planets” is an article written by Neil de Grasse Tyson that sums up the creation of the planets and why life is on Earth. He sets it to the story of Goldilocks‚ where Earth is the Little Bear’s stuff. He then breaks down the different reasons as to why we continue to have life. All of that is the basics to understanding Exoplanets. Exoplanets are just planets that orbit a star that is not our Sun. There is a subsection of exoplanets called

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
