At the end, hover over each planet, it will tell you their name and their nickname. There are 4 steps to the formation of the solar system 1) The solar nebula collapses in on top of itself. 2) The sun forms from all of the atoms that exploded in the solar nebula. 3) Small rocks clump together using gravity and magnetism to become bigger and bigger, eventually to the size of planetesimals. 4) Planetesimals collide creating the planets their moons. Want more information on the Solar System? Read this short essay I wrote! Gravity had a big impact on the formation of our galaxy, solar system, and planets. Large objects in space attract other objects, including other large objects, which is very important to know about the formation of our galaxy, because that is how it formed. According to the article, “How did the Milky Way Form?” Written by Universe Today “The stars started to gravitationally attract each other into larger groups.” These groups are known as galaxies. During the formation of the solar system, a cloud of gas was pulled together by gravity and created our sun, the center of our solar system. The article, “How did the solar system form,” published by Space, further proves my point. “Solar system formation began approximately 4.5 billion years ago, when gravity pulled a cloud of dust and gas together to form our solar system.” Gravity also led to the formation of our planets. The article, “Our solar system,” written by NASA, provides great evidence for this. It states, “...clumps smashed into one another forming larger objects. Some of them grew big enough for their gravity to shape them into spheres, becoming planets…” Not only did gravity have an impact on the formation of our galaxy, solar system, and planets, it also had an impact on how they moved. Evidence of this motion is provided by the article, “The new history of the Milky Way,” by Quanta Magazine. Quanta Magazine wrote “Our Milky Way galaxy came together nearly 14 billion years ago when enormous clouds of gas and dust coalesced under the force of gravity.” Not only does motion occur in the galaxy because of gravity, it happens in our solar system too. It does so by keeping objects in its orbit. An article written by Sciencing explains to readers, “The sun is extremely massive, thus it holds very distant objects, like the outer planets and comets, in its orbit.” This piece of evidence also explains how the planets move because of gravity. The sun drags the planets around in elliptical orbits around itself. I made a model of the solar system on Scratch, and it is a great visual representation of the formation and movement that occurs inside of our solar system. My model shows how the sun formed from an exploding solar nebula, and the planets formed from smaller planetesimals. It also showed that the planets were set in an orbit around the sun. There are blue lines that show the paths that all of the planets follow around the sun. Overall gravity was a very important factor in the motion and formation of our planets, solar system, and galaxy.
