The Theory Of The Solar System

Scientists have found that the Earth was formed about 4.6 billion years ago by collisions in the giant disc-shaped cloud of material that also formed the Sun. As gravity slowly gathered this gas and dust together into clumps, it became asteroids and small early planets called planetesimals. These objects collided repeatedly and gradually got bigger, building up the planets in the Solar System. Although scientists are very close to answering the question, they still continue to search for the exact answer to how the Earth was created. With all the evidence presented, it is hard to refute from scientific theories. This becomes cumbersome to many religions because in their eyes God has always been the creator of the Earth.

The study of Kuiper Belt will likely continue to provide more information on how our solar system was formed and its origins. The material in the Kuiper Belt are what’s left over after the rocks, dust and gas pulled together form

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

the planets fall around the Sun. Each of these objects balances the Sun 's force of gravity

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.

The history of our solar system is one topic that scientists were able to gain information on due to the Philae mission. “A Success in Space”, an article that reveals the story of the Philae one mission, states, “Researchers consider comets the remains of the ancient solar system.” (Keady 5) This quote shows that comets can be a key to finding more about the remains of the solar system from long ago. Ashley Yeager, the author of the article “Comet probe may shed light on Earth’s past” wrote, “By studying these hunks of rock, dust and ice, scientists hope to better understand the early history of the solar system—including Earth’s early years.” (8) This example proves that scientists hope that comets can help them assimilate more information on the history of our

the heliocentric solar system. Johannes Kepler further modified the heliocentric system, by mathematically showing that the planets’ orbits are elliptical. With his invention of the telescope, Galileo made new observations about the solar system and found mathematical laws that described the movement of the planets. Later, Isaac Newton established a universal law of gravity. With the new scientific discoveries, the gap between religion and science increased. Science revolutionized the human though and its understanding of the universe.

Anybody can tell just by looking at the diagrams of the solar system from the two different time periods that there was a big gap in between the thoughts of the two men who made them. Ptolemy, the man who made it in the medieval period, made people believe that the earth was in the center of our solar system, and the sun was the third planet from the earth. He also made people believe that, “the outer sphere… the Empire of Heaven and Home of God and the Elect” (DBQ Online Document C). These facts were not only untrue, but they also caused everyone to believe that this was correct.

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

Have you ever wondered why the Earth is spinning? This question baffled scientists for years. Well, I can tell you what i know.To keep it short, it involves going a long way back into the past to just when our Solar System was just forming.

Firstly, to deduce how the Earth came to form the structures we know today in modern Earth, we must go back

Johannes Kepler was a German astronomer and mathematician who lived between 1671-1630. Kepler was a Copernican and initially believed that planets should follow perfectly circular orbits (“Johan Kepler” 1). During this time period, Ptolemy’s geocentric theory of the solar system was accepted. Ptolemy’s theory stated that Earth is at the center of the universe and stationary; closest to Earth is the Moon, and beyond it, expanding towards the outside, are Mercury, Venus, and the Sun in a straight line, followed by Mars, Jupiter, Saturn, and the “fixed stars”. The Ptolemaic system explained the numerous observed motions of the planets as having small spherical orbits called epicycles (“Astronomy” 2). Kepler is best known for introducing three

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,

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, and astrological practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World . In some cultures astronomical data was used for astrological prognostication.
