Solar System Lab Report

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.

Throughout generations stories were passed down about how things could've been created like the earth, mankind, and even the stars. Every culture and religion has their own myth of how things came to be. The Hindu’s, Native American’s, and the Chinese all made up stories about how the stars were created.

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

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 life cycle of the Sun starts like all stars with a cloud of dust and gas made up of mostly hydrogen. If the cloud cools, it will shrink because of the gravitational pull between the particles

It started five billion years ago as a cloud of dust and gas about 10 billion kilometers in diameter that rotated slowly in space. This massive cloud shrank over time because of its own gravitational pull, or because of an exploding passing star. Most material collected in the center and it rotated faster as it shrank. Compression of the material made it hotter, which started hydrogen fusion, forming the sun. Ten percent of the material in the cloud formed a disk around the sun. Due to friction in the disk, most of the mass collected into whirlpools. These whirlpools shrank to form protoplanets. These protoplanets became planets and moons. Excess material became comets, asteroids, and meteoroids. A problem with this hypothesis is that it would be unlikely for a passing star to explode, because stars are very far apart from each other. Also, as with the nebular hypothesis, it would take an unreasonable amount of gravitational pull for the disk to condense into

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

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.
