The Solar System : The History Of The Solar System

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 sun is a star that is made up of hydrogen gas. The sun is unlike other stars that we see in the sky because the sun delivers energy and radiation that allows to living things to exist. Also, the sun is much closer than the other stars in the sky.

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

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

Stars like our Sun, which are no more than 1.44 solar masses, will undergo fusion of hydrogen into helium. Over its life time the star slowly uses its supply of hydrogen by fusing it into helium. These reactions require high temperatures. Eventually the star will completely fuse hydrogen into helium in its core leaving inadequate amounts of thermal pressure to balance gravity. This will cause the centre of the star to contract to compensate for the heat energy lost.

Years and years ago, there were only eight known planets that orbit our sun; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Eight planets until that fateful day when Clyde W. Tombaugh discovered our ninth planet. Although, a little credit should be given to Percival Lowell,

The sun is the glue that holds this galaxy together, and makes a stabilized environment on Earth to survive, and plays a substantial role for everything that happens to the earth. The sun is the largest amount of matter in our galaxy, therefore also having the most amount of mass also giving it the strongest gravitational pull. Since it has the strongest gravitational pull in the galaxy, the sun is the center of our galaxy having all the planets and asteroids surrounding it. Now this doesn't mean the sun is the biggest star there is possible, in fact the sun is just an average star. The average stars are dwarf stars, and the sun is a yellow dwarf star. Now we have dwarf planets like Pluto, compare Pluto to the Earth, now compare the Earth to the sun. That just leaves the question how big is a star? The sun only looks bigger to us than most stars because we are the 3rd planet

There a many hypotheses explaining how the solar system formed. In science class, we learned about three hypotheses explaining the formation of the solar system. We learned about the nebular, protoplanet, and planetisemal hypotheses.

The solar system started out as a cloud of gas and dust. Now, it is full of planets, moons, asteroids and comets. They began forming more than 4 billion years ago.

Have you ever wondered about the origins of the solar system and how it evolved? The philae mission was a probe that went into space and landed on a comet to take pictures and get samples of the comet’s surface to hopefully get more information about the origins of the solar system and how it evolved. The philae mission was important for scientific research because it could give researchers valuable information about the origins of the solar system and how it evolved.

There are eight planets in the solar system Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. There is also a Dwarf planet Pluto.

The solar system formed when a cloud of interstellar dust and gas collapsed. The oldest meteorite specimens are remnants of the very first geologic processes to occur in our solar system 4.6 billion years ago. Because the interstellar cloud had been slowly spinning, the result was a nearly flat rotating disk which is referred to as the solar nebula. Much of the dust and gas in the disk moved to the center of the nebula where it fed a growing protostar which eventually became our sun.
