The Formation of Solar System Essay

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

By the 16th century, astronomers began to note irregularities in the accepted model of the solar system. In the early 1500s, Nicolaus Copernicus noted that the planets had slight discrepancies between their observed and presumed positions. Copernicus thought that the Sun was

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.

Astronomers have identified plenty of objects that were circulating the sun farther away from Neptune since the year 1992. According to research, there are more than 70,000 of these small objects named as Trans-Neptunians, which had a diameter that was larger than 100 km. Also, these objects extended from Neptune’s orbit from 30 astronomical units (AU) to 50 astronomical units. There is a thick band in which these Trans-Neptunians were restricted in and this ring was named as the Kuiper Belt. One may ponder what is the significance of the Kuiper Belt? Astronomers believe that the objects within the Kuiper Belt may be the ancient remains from the early stages of development of the solar system.

From the time of Aristotle up until the time of Newton there were five models of what humans thought of the universe. The astronomers who developed these models were Aristotle, Ptolemy, Copernicus, Tycho Brahe, Kepler, Galileo and Newton.

It is easy to flip to the index of an astronomy textbook to discover that, say, the Sun lies 150 million kilometers away from Earth. It is far more difficult (if not impossible), however, to picture this distance in our mind. In this exercise, we will learn to access the often unpalatable distances encountered in astronomy by simply scaling the huge distances to more recognizable, familiar numbers. So long as every distance within the system of interest is scaled by the same

Made up of all the planets that orbit the sun, the Solar System has over 100 worlds. In addition to eight planets without Pluto and nine with Pluto, the Solar System also consist of gas, dust, minor planets,asteroids, and moons. Containing 98% of all the materials in the Solar System, the sun is an extremely important object in the Solar System. Everything in the Solar System orbits or revolves around the sun. The larger an object is in space the more gravity it has and that why the enormous sun contains 98% of all the materials in the Solar System. The Solar System basically is just the planets moving rapidly and trying to fly away from the sun. They end up in in the emptiness of outer space. The outcome of the planets trying to fly away and

Do you want to know more about the universe, but dont have the time to actually pursue a detailed study? Then Astrophysics for People in a Hurry is exactly the book for you. The book describes the origins of the universe, delves deep into how it functions, and discusses different concepts of physics. Tyson tries to explain these concepts in the most simplified manner with a lot of humor. He also leaves us with not just a better sense of understanding of the universe, but also many questions about how to relate with the infinite cosmos with our own human and limited understanding.

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

Known as a dwarf planet, Pluto is in the Kuiper belt, a ring of bodies beyond Neptune. It was the first discovered Kuiper belt object.

The life cycle of the star is a long process that has taken place for billions of years and will continue to take place long after our star is no longer in existence. In this essay I will be explaining the magnificent process of how a star is first born till the end of its life cycle. First, I will be explaining how the star is first formed in all its beauty big or small. Then, I will be explaining the path of an average star like our own sun will take. After, I will be explaining the journey of a massive star in all its glory till its destructive end. All stars are first formed in clouds of gas called nebulae, turbulence deep within the nebulae causes cores to form as the mass begins to grow the nebulae begins to collapse upon itself due to

Humans have longed to believe in extrasolar planets, as surely there have to be planets elsewhere in the universe. Claims of supposedly discovered extrasolar planets can be dated back to 1855 when Captain S. W. Jacobs from the Madras observatory, claimed that he had discovered a planet orbiting a binary system (Jacobs 1855), all the way up until 1991 when a team of astronomers announced then retracted the alleged discovery of an extrasolar planet around a pulsar star (Lyne and Bailes 1992). Planets are extremely hard to detect as they are a very faint light source and the light from its parent star is much brighter and essentially blocks out light from a planet (Winters 1996). It was not until 1992 when the first exoplanets were confirmed

"A planet is a celestial body that revolves around a central star and does not shine by its own light " (Grolier, 1992). The only planetary system that is known to man is our

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,

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.
