Solar System and Gravity

The Law of ellipses, which means that each planet travels around the sun in an ellipses.

Before Newton talked about gravitation the main knowledge of scientists was a elementary knowledge of optics, mechanics and astronomy.Copernicus Kepler and Galileo provided the background knowledge of the stars and planets, but Newton used their data to discover the whole gravitational system.10Newton reasoned that the planets and all other physical objects in the universe moved through mutual attraction of gravity.Newton said that every other object in the universe affected every other object through gravity.This explained why the planets move in an orderly fashion. Newton found that “the force of gravity towards the whole planet did arise from and was compounded of the forces of gravity towards all it’s parts, and towards every one part was in the inverse proportion of the squares of the distances from this part.”Newton proves all of this mathematically. This was known to be the single most important contribution to physics that ever has been made.11

This does not, though, mean that there is no objective law of gravity which exists independently of human society. The beliefs in gravity which I described are attempts by human societies to approximate reality. Clearly, some approximations are better than others. Perhaps the current belief in the curvature of space-time is also incorrect and will later be replaced by an even better approximation. However, most people would have no problem agreeing that the curvature of space-time explanation of gravity is a better approximation to reality than the explanations which came before it.

Each Planet orbits this is true, but why? Its because of the pull of the Sun's gravity as it is stronger

Roughly 5 billion years ago, our solar system no sun. Instead all that exists in our solar system today, used to form a gigantic gas cloud, floating in the milky way away from the center of the universe. Something traveling from the center of the universe faster than our gas cloud of a system collided with our "solar system" this caused a fission reaction, creating a focal point that "sucked" in all the lightest of elements in our solar system, Mostly Hydrogen I'd assume*. This is how our sun was created and like an implosion, the heat of this reaction, boiled the gasses, and the force of the object that passed through our "cloud" created energy and momentum. The combination of heat, and movement, caused particles to collide, and bond together,

“Newton’s law of universal gravitation states that the gravitational attraction between two bodies is directly proportional to their masses, and inversely proportional to the square of the distance between the bodies (Sumich, J.L., 1996; Thurman, H.V., 1994).”

Gravity Plays a big role in our solar system! Why does the moon orbit around the earth? Gravity. Why do the planets orbit around the sun? Gravity.? Gravity! You know what else gravity affects, the shape of objects. All of the planets are roughly spherical, right? Well, that's also because of gravity!

Gravity impacted the solar system in forming ,and still impacts our solar system today. Gravity does a lot of things to our universe and solar system here are a few. In Origins of Everything it states “Another possibility of the future of the evolutionary Universe is that gravity of all the matter might eventually pull everything back together again in a gigantic collapse that explodes and starts the Universe all over again.” This is a possibility because it happened once and maybe it will happen again. ANother example of something gravity can do is from Gravity and Orbits, I said that in the simulation with the gravity on, the orbits stayed the same and weren’t erratic but with the gravity of the planets flew off into space and so would the sun. My last piece of evidence that gravity has a huge part of formation of our solar system is from Objects in Orbit. “ Gravity kept pulling matter toward the center of the disk… The center of the disk became hotter and hotter.” Gravity is the reason we are here today, it made our star then our planets and keeps us from floating off into space.

was not pulling them in using gravity, the planets would simply continue in a straight

As humans we have always try to understand how the universe really works. How does the moon form? How does water really flow? How did the earth form? To provide some explanation on how the stars and the planet worked Nicolaus Corpernicus “an astronomer and mathematician” created “his own celestial model of a heliocentric planetary system.” His theory was there are multiple Center in the celestial sphere where the moon and stars exist. The earth is the center and the planets does not rotate around it. The sun is close to the midpoint of the world, but the spheres doesn’t rotate around it either. The stars are located on a permanent sphere, which is considered the firmament and does not move, and the earth has multiple motion which not only

He also proved that there is a force of mutual attraction between the sun and the planets makes the planets

Gravity is a force of attraction between objects that is important because our solar system’s structure relies on it. In the article titles, “Gravity and the Solar System.” it says, “It accounts for the formation of planets, stars, and galaxies. It also keeps smaller bodies in orbit around another body in space.” This quote is saying that gravity is an important force that makes planets orbit the sun. If it didn’t do this the planets would have no light or heat because they would be shooting through space in a straight line. Another quote from “Gravity and the Solar System” is, “Gravity keeps objects, such as satellites, in orbit around Earth. Gravity also affects the way in which planets move and how they are formed.” This demonstrates how

The concept of gravitational attraction can be understood by considering weight, which is the gravitational force that the earth exerts on an object, on or near its surface. Without gravitational attraction, the earth would not be in the sun’s orbit, rain would not fall, rivers would not flow and the sea would be a mass of stagnant water. With more exploration of space and new technology, we are now able to examine the effects that gravitational attraction has on earth and its living inhabitants.

items, likes stones, tend to fall downwards and light to go upwards, these practices are gravity
