Protoplanet Hypothesis: How Was Our Solar System Created?

Astronomer Nicolaus Copernicus observed that the Planets and stars revolved around the sun not the Earth.

Planets revolve, or orbit, the Sun because of gravity keeping them in their orbit. The Sun's gravity has a pull on the planets which prevents them from falling into each other. Newton discovered the law of gravity which states that a particle attracts other particles by using a force that is directly proportional to their masses and inversely proportional of the distance

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.

Stellar evolution stars exist because of gravity. The two opposing forces in a star are gravity (contracts) and thermal nuclear energy (expands). Stage 1 Birth is where gravity contracts the cloud and the temperature rises, becoming a protostar. Protostars are a hypothetical cloud of dust and atoms in space which are believed to develop into a star. Astronomers are fairly certain of their existence. Protostars are formed about a million years after a gas clump from an interstellar gas cloud has started

As technology improves it is even more likely that we will discover more about our solar system. A great current example of this is the claim of ‘Planet X’. Researchers say that there is possibly another planet in our solar system that orbits beyond Neptune but is large in size. Two scientists recently announced evidence that a body nearly the size of Neptune that orbits the sun every 15,000 years. Since it has never been seen, because it only orbits every 15,000 years, scientists and researchers cannot make a factual claim on the body even though there is strong evidence of its

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,

“The early Earth was probably partially or largely molten” (The Solar Nebula. N.d). Over time the earth cooled and the crust was formed. “Much continental crust, the most silica rich and least dense kind, has been produced by 2.5 billion years” (The Solar Nebula. N.d). Over a period of time and a series of volcanic eruptions water vapor was thrown into the atmosphere and eventually condensed to form the oceans. From a spinning cloud of dust the evolutionary process began and the Earth that is inhabited today came into existence according to the nebular hypothesis.

The Ptolemaic view of the motions of the stars was earth centric, or geocentric. Ptolemy believed that all the planets revolved around the earth, the earth was the center of the universe. Copernicus on the other hand held the belief that the universe revolved around the sun, or that the universe was heliocentric. Copernicus also only considered there to only be six planets, as he didn’t count the moon like Ptolemy. Kepler held similar beliefs t Copernicus, and believed that the reason why a god-created universe only had six planets instead of seven was based on Plato’s idea of the five Platonic Solids. That just like there are only five forms of matter and five platonic solids, the universe must have been intelligently created in a similar

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.

planets in our solar system came from. Does or did our star, the sun, have a

Several unresolved problems remain concerning the Orion Nebula. The fate of the protoplanetary disks, for example, is presently impossible to predict. Without a more detailed understanding of how planets actually form, it cannot be assumed that the events within the Orion Nebula are analogous to the events that led to the formation of the planets in the solar system. Furthermore, the detection of water in the nebula has revealed the need to revise the theory of star formation to

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,
