The Solar System

Ptolemy, a Roman astronomer came up with the theory that the universe revolved around Earth and all the creatures inhabiting it (Doc. C). This theory, The Geocentric Universe of Ptolemy, was adjusted by most of the people during The Middle Ages. However, much later on, Nicolaus Copernicus, a Polish astronomer, disagreed with Ptolemy’s theory. With his use of math and reason, he came up with a new theory called The Heliocentric Universe of Copernicus (Doc. C). He said that the universe & Earth itself revolves around the sun. The Church denied this theory because they did not want to be proven wrong. If the Church was wrong about this part of the universe, this would then cause man to wonder what else they could be wrong about, or even lied to them about. This new theory taught men to think for themselves and not to rely on the Church for

Gravity: Gravity is a force of nature that keeps things on Earth instead of floating out of the atmosphere.

The solar system was created 4.6 billion years ago by a gravitational collapse. A solar system is a star that has planets, moons, asteroids, comets, and meteoroids travel around it. The solar system contains eight known planets which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune. There is around several hundred dwarf plants but only five are currently recognized. The solar system has about 181 moons which orbit around the planets in the solar system. There is also about 150 million asteroids and 3,406 comets also in the solar system.

Among these people were Copernicus who believed the sun was at the center of the world and the earth, stars and planets revolved around it. Danish astronomer Brahe helped contribute to this idea by contributing a large mass of data about the universe that he was able to discover. His student Kepler kept his ideas going, as he formulated many laws of planetary motion. He said the orbits around the sun were elliptical, planets don’t move in a uniform speed and the time a planet completes its orbit is related to its distance from the sun. Meanwhile, Florentine Galileo decided to use experiments to find out what happened and not what should happen, and discovered that a uniform force makes a uniform acceleration as well as inertia laws, that an object will be in motion forever unless stopped by another force.

While the Roman Catholic Church believed that the earth was the center of the universe, Nicolaus Copernicus’s discovered that the Earth actually was one of the planets hat revolved around the sun. “For, in the first place, they are so uncertain about the motion of the sun and moon that they cannot establish and observe a constant length even for the tropical year. (Document 1)” The church belief did not make sense because it was wrong. They were going off wrong information that they could not establish a constant year, which confuses people. Nicolaus said that the earth moved around the sun, which made more sense and

Before the scientific revolution people believed that Earth was the center of the universe. That was widely believed by everyone until Nicholas Copernicus said that the sun was the center of the universe and the Earth orbited around it. Document one

The Scientific Revolution changed society with the birth of “modern science”; it changed the way people thought about the physical world around them. The same spirit of inquiry that fueled the Renaissance, led scientists to question traditional beliefs about the workings of the universe. The conflict all began with Copernicus’ heliocentric model being introduced to the world- going against the Church’s traditional teachings. Nicolaus Copernicus developed the heliocentric model of the universe- stating that the sun is the center, and that other planets revolve around it. Despite his calculations, people disagreed and kept on believing in Ptolemy’s geocentric model.

Although all nine planets are a huge part of the solar system there's a lot more to the solar system than the nine planets. According to scientist the Solar System started out as an enormous cloud of gas and dust. Scientist believe that the cloud of dust and gas began to collapse under the weight of its own gravity and it did. The matter that was kept within itself began moving in a giant circle and at the center of the spinning cloud a tiny star began to form. The star eventually grew larger and collected more dust and gas that collapsed into it. Farther from the center of the mass that was being formed there was many smaller clumps of dust and gas that were also collapsing. The large cloud in the center eventually became the sun while the smaller clumps formed the planets, moons, comets and,

In inspiring people to have the passion in understanding the universal laws that govern us all, Professor Stephen Hawking reminds us on his speech for his 70th birthday to “remember to look up at the stars and not down at your feet” (enoch, 2012). Many scientists have been “looking up” and have discovered answers to the many questions that we have of the universe for ages. They have constructed theories, launched satellites, observed stellar phenomena, and even sent living beings in space to gain more understanding of the existence of everything. After centuries of research and observation, there are still some aspects of Astronomy that are still to be explored. One of them is the evolution of the Solar System, which is composed of the Sun and everything that travels around it. This includes eight planets and their natural satellites such as the Earth’s moon; dwarf planets such as Pluto and Ceres; asteroids; comets and meteoroids (Solar System Exploration, 2014). The Solar System is located in the Milky Way Galaxy, which is a part of a galactic group under the Virgo Supercluster. Figure 1 shows the location of our Solar System in the Universe. Many theories have been proposed on how the Solar System existed, but none has been completely successful. This spans from the time of the Ancient Greeks to the present 21st Century. As of now, the widely accepted theory is the Nebular Theory, which describes how the Solar System started as a large cloud of gas that contracted under

Nicholas Copernicus was the first to question the universal truths and teachings of the church. He devised a theory that the earth along with the other planets revolved around the sun. This theory disagreed with Aristotle and the old teachings that the universe revolved around the earth, and that man was the center of the universe.

Thought history scientists’ finding have been ignored, only to be discovered that their information was beneficial. In the 1600s and 1700s, many astronomers and mechanics were focused on finding a way to find the longitude of a ship’s position at sea. John Harrison, a self-taught carpenter and clockmaker was able to create a solution, but no one with enough power to enforce his studies would listen to his ideas. Similar to this, when Nicolaus Copernicus discovered that the earth revolved around the sun, no one believed him because the belief at the time was that the earth was the center of the universe. Despite no one appreciating what the two had discovered, several years after they had died, their theories surfaced again and people began

In 1543 Nicholas Copernicus, a Polish Canon, published “On the Revolution of the Celestial Orbs”. The popular view is that Copernicus discovered that the earth revolves

One of his biggest and most significant discoveries was the confirmation that the sun was the center of the universe. This idea of a sun-centered universe is called a heliocentric universe. This idea was first proposed by Nicolaus Copernicus. The Catholic Church believed that the Earth was the center of the universe. This is called a geocentric universe. When Galileo announced his discovery it was immediately denied by the

solar system. It is made up of nine planets which range in size and make-up. The nine major planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. There are also many other minor planets which are also in

Scientists believe the solar system began about 5 billion years ago, perhaps when a nearby star exploded and caused a large cloud of dust and gas to collapse in on itself. The hot, central part of the cloud became the sun, while some smaller pieces formed around it and became the planets. Other fragments became asteroids and comets,
