The Solar System Of The Sun

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.

"Our solar system consists of one star and some debris," said Carl Sagan. There are many differences and similarities between the Inner and Outer planets. Our solar system is comprised of the Sun being in the middle, then followed by planets rotating it. The planets which orbit the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The Inner planets are very different from Outer planets and the Outer planets are completely different from Inner planets, but both are very similar in many ways. Our planets in the solar system have many similarities and differences.

The Inner Planets are Mercury, Venus, Earth, and Mars. Mercury is the closest to the sun, so it has extreme temperatures. Mercury also has frozen water on its surface, and during some of the seasons, it melts. Mercury is the smallest planet, and it has a very thin atmosphere.

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 the heart of our solar system” (NASA Solar System Exploration) which is located at the center of the solar system. The sun has a radius of 432,168.6 miles. You would need 1.3 million Earths to fill up the sun. But the sun is not the largest star there are several that are much larger. The sun is the closest star to Earth which is around 93 million miles. The sun is like a big ball of gas. “In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium.” (NASA Solar System Exploration). But if you measure by mass the sun is made up of “70.6% hydrogen and 27.4% helium.” (NASA Solar System Exploration). Gravitational attraction which is made by pressure and temperature in the core holds together the sun. There is three main layers in the sun which are the core, the radiative zone, and the convective zone. Inside the core temperatures can reach 27 million degrees Fahrenheit

b. The Sun is the focal point of our solar system, because all of the planets orbit the Sun.

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.

The reading on terrestrial planets from chapter 6 provides readers with a little insight on the similarities and differences between the planets. These planets include Earth, Venus, Mercury, and Mars. Although these planets have very different properties, they are connected due to their history. There are scientific laws that help people understand, compare, and contrast these planets, such as gravity, chemical composition, and temperature.

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

Neptune has a planetary ring system, consists of ice particles coated with silicates or carbon based material. There are five rings. The three main rings are Adams Ring, Le Verrier Ring, and Galle Ring,

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

Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earth’s neighbours. They all have the same stars in the sky and orbit the same sun.

The heat and light of the sun come from the nuclear reactions of hydrogen, carbon, nitrogen, and helium. So the sun is just one great big atom smashing, gas creating, nuclear furnace that gives off much appreciated energy. But this is not all that happens on the sun’s surface, some exciting stuff does happen up there every once in a while.
