does anybody know the formation of the solar system?

Don't want to cut and paste it all, but you can find that information on Wikipedia in the third section down "Age and origin of the solar system"\n\nLink: http://en.wikipedia.org/wiki/Solar_system\n\n(Or you can just wait a few minutes until someone else cuts & pastes the whole thing.\n\nSome other good sources:\nhttp://www.nineplanets.org/origin.html\nhttp://www.enchantedlearning.com/subjects/astronomy/solarsystem/origins.shtml\nhttp://www.britannica.com/eb/article-27552

Look up "the nebular hypothesis".  you also are confusing the Milky Way (a disk shaped system of a hundred billion stars or so of which our sun is a part) and the Solar System (our sun and its surrounding planets and other assorted detritus.)\n\nhttp://en.wikipedia.org/wiki/Solar_nebula

There are two types in the solar system: \n- the terrestrial or rocky planets: Mercury, Venus, Earth, and Mars, which are composed primarily of rock (Si and C oxydes) and metal (Fe, Ni). \n- the gas planets: Jupiter, Saturn, Uranus, and Neptune, which are composed primarily of hydrogen and helium, just like the sun.\n\nYou notice immediately that there is a difference in size between the two groups. And that explains everything: the sun and therefore the original dust cloud which was at the origin of the solar system, contains 75% hydrogen, 24 % helium and 1% other stuff. \n\nThe sun swept clean the inner region of the solar system and the planets were small. To small to held on to the volatile gases H and He. Those escaped and rocky bodies remained.\n\nBut farther away from the sun, the planets themselves cleaned up space. They could grow much bigger, and kept most of their H and He.

The big bang; the theory that the solar system was created by a large explosion of dust and gas. The dust and gas was pulled together over many years by gravity and formed the planets.

Yes, Earth is the third planet from the sun.\n\nNo, Earth is not an exact sphere.  The Earth ispudgy.  It has a slight "bulge" around the Equator.  We're close enough, and we're certainly not flat, but we're not on a perfectly round planet.\n\nThe planets in the solar system are (in order from sun, outwards):\n\nMercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, & Pluto.  There is also an arguable "10th planet", but until NASA names it (and confirms it's a PLANET, not just a rock) I'll say there's nine.\n\nAlso, in between Mars & Jupiter is the Astroid Belt, which some think was once a planet that exploded long ago.\n\nFor (really) in-depth information, visit Wikipedia:

Earth formed as part of the birth of the solar system: what eventually became the solar system initially existed as a large, rotating cloud of dust and gas. It was composed of hydrogen and helium produced in the Big Bang, as well as heavier elements produced by stars long gone. Then, about 4.6 billion years ago (fifteen to thirty minutes before our imaginary clock started), a nearby star probably became a supernova.\nThe explosion sent a shock wave toward the solar nebula and caused it to contract. \n\nAs the cloud continued to rotate, gravity and inertia flattened the cloud into a disc, perpendicular to its axis of rotation. Most of the mass concentrated in the middle and began to heat up. Meanwhile, as gravity caused matter to condense around dust particles, the rest of the disc started to break up into rings. Small fragments collided and became larger fragments. These included one collection approximately 150 million kilometers from the center: Earth. As the Sun condensed and heated, fusion began, and the resulting solar wind cleared out most of the material in the disc that had not already condensed into larger bodies.

That's a good question. I'm quite sure "God made it" isn't the answer you're looking for, especially since you posted this in the science section. \n\nReligion seems to have all the answers, but those answers never satisfy the appetite of curiosity and learning. Below are several different worded versions of the same basic theory of how the Earth (and other planets) formed. \n\nBe sure to check out the sources.\n\n1. The planets formed from the material left over as a result of our sun's formation. As the nebulous cloud condensed and began to rotate, most of the gas condensed into what is now our sun. The remaining material formed what is now the planets and the other bodies in our solar system.\n\n2. The prevailing theory is that they are formed from those remnants of a nebula that do not condense under gravity to form a protostar. Instead, these remnants become a thin disc of dust and gas revolving around the protostar and begin to condense about local concentrations of mass within the disc. These concentrations become ever more dense until they collapse inward under gravity to form protoplanets. When the protostar has grown such that it ignites to form a star, its solar wind blows away most of the disc's remaining material. Thereafter there still may be many protoplanets orbiting the star or each other, but over time many will collide, either to form a single larger planet or release material for other larger protoplanets or planets to absorb. Meanwhile, protoplanets that have avoided collisions may become moons of larger planets.\n\n3. The most widely accepted model for the origin of the Solar System is called the  nebula theory. Most generally phrased, the theory states that the Solar System condensed from a large, lumpy cloud of cold gas and dust.\n\n4. Solar Nebula Theory

Ask the designer of the Solar System he probably know.

Seeing as our solar system must have been formed from the last dying sneeze of a star (as there are very heavy elements that couldn't be present otherwise), thats where we came from. We are basically star snot.

You've been to Pluto? \nWhat's it like?\n\nThis is a nonproven theory:\nBecause when the Sun was forming, and condensing to it's present size, it spun faster and faster as it grew smaller. The first things to be spun off were rings of light gases that formed the outer gas planets. As it got hotter and smaller and faster, rings of heavier materials were flung off, creating the inner rocky and metallic planets. Pluto is technically a captured comet or other stray chunk, and probably came from further out in the system, perhaps a remnant of stars which previously exploded. We won't know until we get there.

It has to do with the formation of the planets from the solar nebula based on the "nebular hypothesis."  That is why they are all on different orbits.

The solar system is believed to be approximately 4.6 billion years old. We do not know in what order they were formed other than it was approximately 100 million years after the sun was formed.

Solar system is 11 letters in size.\n\nTHE solar system or A solar system are different matters\n\nWe have these things in English called defintite articles. Words like "A" and "THE". Learn them. Use them.

Actually, all of them simultaneously. Sun and the planets were all formed from the remnant gas cloud of the supernova explosion of a star much larger than Sun. While most of the gas cloud fell back to the center forming our Sun, the most dominant center of the materials in the peripheral volume ended up forming Jupiter, the largest planet.\n\nTherefore when the solar system is in its nascent stage of formation, if you see which proto-planet has formed ahead of other planets, you may see Jupiter to be the first, but other planets have also started developing, depending on what's your yardstick of measurement for calling an object a planet.\n\nClearly 4-5 billion years ago, when the protoplanets were still under development, there were still numerous smaller size objects whirling around Sun and the gas cloud would still not have settled.

now i dont know much detail, but according to science, there was what is called the Big Bang.  here, this big, huge gas ball started spinning really really fast and formed the milky way, then, smaller gas balls were formed which are the plantes.  then the moons are astroids lurned into the planet's gravitational force.  (just remember-this is not detailed ONE BIT and i might even be wrong on some of this-but the basic idea is correct.)

It goes back to when the solar system was formed.  The sun (and the planets, for that matter) were formed when a gigantic cloud of gas and dust collapsed.  When that cloud collapsed, it had something called 'angular momentum', which really just means that it was spinning a little bit.  When a large, slowly spinning thing collapses to something smaller, the rate of rotation speeds up (think about an ice skater that pulls her arms in...she spins up!).  Anyway, so now we have all this gas and dust in a disk that's orbiting the new Sun.  The dust eventually forms into planets.  As the dust collapses into new planets, the same thing happens, and the planets start spinning themselves.  So basically, the earth and moon and whatnot spin because of angular momentum.  I hope this made sense/helped!
