Solar System Research Paper

There are many differences among our planets and moons in our Solar System. The geologic activity, composition, interior structure, magnetic field, and atmosphere are all factors that help give these planets and moons there identity. We have sent probes over the years to help examine these properties.

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

The telescope is an optical instrument designed to make distant objects appear nearer. It contains an arrangement of lenses or mirrors or both that gathers visible light, permitting direct observation or photographic recording of distant objects. (Lacki, B. C. 2011). With the use of telescopes we have been able to learn a lot more about the planets in our universe. It has helped us understand about some of the history of everything around us. Also it has been able to track asteroids and comets or any randomly flying objet in outer space that might become threatening to our planet.

During the first millennium B.C. scientists realized that astronomy had to become more scientific. Middle Eastern and Chinese cultures started studying the Sun, stars and the planets more closely in an attempt to learn more about our position in the universe.. Star positions also became important tools in understanding directions, and helping with navigation. One philosopher stated in 434 B.C. that the Sun was a ball of fire 60 kilometres in diameter, hovering 6500 kilometres above Earth’s surface. Around 130 B.C., Ptolemy wrote Almagest, which was a huge collection of astronomical data which included mathematical models, information about eclipses, and planetary and stellar positions and movements. It remained a major go to book for astronomy for hundreds of years, and was not seriously challenged until Copernicus disputed the geocentric model of the solar system in the 1500’s

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 currently accepted model of the Big Bang is "that the the universe is not static but is expanding and that the expansion began in an incredibly hot, dense Big Bang approximately 13.72 billion years ago" (Krause, 2012, p. 25). This hot, dense bit of matter was only a few millimeters across and contained all of the matter and energy that makes up our universe and as it expanded, it cooled and over the billions of years of existence the universe settled into its current state.

Astronomers study the planets, stars, and other celestial objects to try to understand how the universe works. They also study things like collisions, black holes and other things that could potentially affect earth. Astronomers gain information about objects in space from telescopes, and satellites. They can also use mathematical equations to find the positions of planets and stars in our universe. These telescopes and satellites observe light reflected by things such as planets, meteors, or stars in space and use it to make observations. Then the Astronomers job is to collect and analyze the data observed.

We are not quite sure exactly how it happened or even how long it took to happen. According to www. Space.com it underwent an incredible growth spurt and doubled in size at least 90 times. This marks the beginning of an extraordinary set of circumstances that created a perfect storm. It was a chaotic set of circumstances the temperature cooled than heated then combined and light appeared and was eventually followed by complete darkness. This light is detectable today and can be researched which will hopefully lead to answers that we have been wanting to answer for many years. Nearly 400 million years after our universe made its appearance in this dramatic and chaotic performance it began to come out of its dark ages. This phase of our universe lasted for a very long time and during this time our very first stars and galaxies appeared. The birth of our Solar System happened approximately after our universe turned 4.6 billion years old. It is believed to have been formed out of a “giant, rotating cloud of gas and dust known as the nebula.” In 1960 dark matter was discovered and remain one of the biggest unanswered questions today. Earth made its entrance approximately 4.54 billion years ago. At its beginning it wouldn’t have been able to be inhabited by humans. Volcanic activity was the norm and at one point there was a collision with another body that is thought

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

The Earth formed 4.6 billion years ago through collisions in the giant disked shape cloud created from the Bing Bang. It is a dynamic planet, with

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

The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once compressed to an unimaginable density. In the big bang, the material exploded outward into the formation of matter that we see today. Shortly after this event everything in the universe was very dense and very hot. It was only until 500,000

most important question. How was the Earth formed? We offer theories but in the end

Astronomers believed the Universe was created about 14 billion years ago. During that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead, and it was insanely hot and dense. Out of nowhere this little bubble started expanding. This expansion created what we know as the Universe. In such little time the Universe went from the size of an atom to the ginormous galaxy we have that is continuously growing.

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,
