what are the theories about the origin of the solar system?

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.

Look up "disk accretion", a popular theory about the formation of our solar system.  This theory explains that as the cloud of dust and gas that formed our system was condensing, it's rotational motion caused an effect similar to centrifugal force which flattened the spinning cloud into a spinning disk.  \n\nI should note that the system isn't exactly flat, a couple of the outer planets have taken on orbits that are quite askew to the disk that the inner planets are aligned with.\n\nThe following web site has some simplified explanations of solar system formation:\nhttp://www.windows.ucar.edu/tour/link=/our_solar_system/formation.html\n\nand more in-depth info at:\nhttp://www.dtm.ciw.edu/akir/Seminar/seminar.html

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.

To (hopefully) answer the question of how Earth came to be. Sure, we have the "Big Bang" theory, but if you've heard of it, and you're familiar with it, it has many holes. \n\nThey hope to collect samples from other planets to see if there were ever inhabitants there (not necessarily humans, but just some kind of organism).\n\nTo have their names in the history books (fame).\n\nTo see if humans have any other option for a planet to live on, besides Earth (Mars is the only planet that even comes close, so far).\n\nTo see if we can duplicate some of our natural resources, since some of ours seem to be running out (i.e. oil). \n\nTo see if there is, in fact "aliens" or "Martians", or just "anything" out there besides us. \n\nAlso, they say that the Sun is going to burn out soon (I forget how long they said we have). We need to find another source of heat and energy. \n\nIf there were in fact inhabitants of other planets, what was their downfall? Why aren't they around anymore? What can be done to prevent us from having the same fate? What can we learn from that? \n\nAs a side note, I've always been fasinated with this subject. Just think, Earth is part of just one solar system, and we can't even get to the furthest planet (Pluto) yet. There could be millions of other solar systems out there, with people just like you and me, doing the same exact things we're doing right now. It's kind of creepy. \n\nAlso, if you go to Google Earth and you type in your address, you can see a satellite view of your house. The picture isn't currrent or live, but that doesn't mean it couldn't be. I see why people get paranoid about being "watched".

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

In the 16th century, Nicolaus Copernicus developed the heliocentric model of the solar system, in which the Sun is stationary at the center, and Earth moves around it. This view of the solar system challenged Ptolemy’s geocentric model, which had been the accepted theory since the 2nd century. In Ptolemy’s model, Earth is stationary in the center of the solar system, and the other planets and the Sun move in complex orbits around it. The Copernican model gradually gained acceptance, for it provided a simpler explanation of the planets' motions.

The first person who proposed that the Earth orbited the Sun was Aristarchus, about 300BC, but his writings have been lost. In 1530 Copernicus published his theory that the Earth orbits the Sun. In 1609 Galileo first used a telescope to view Jupiter's moons. In 1630 Galileo published a document upholding the Copernican system but was forced to recant his beliefs by the inquisition in 1633.

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.

The most widely accepted theory about where our moon came from is that not long after Earth formed it was impacted by an object about the size of Mars. The debris from that impact formed a ring around Earth for a time, and then gradually coalesced into the solid, spherical object we call the moon.

The inclination of the Moon's orbit makes it implausible that the Moon formed along with the Earth or was captured later; its origin is the subject of some scientific debate.\n\nEarly speculation proposed that the Moon broke off from the Earth's crust due to centrifugal force, leaving an ocean basin (presumed to be the Pacific) behind as a scar. This concept requires too great an initial spin of the Earth and the presumption of a Pacific origin is not compatible with the geological standard model, the theory of plate tectonics. Others speculated the Moon formed elsewhere and was captured into its orbit. Two of the other theories include the coformation or condensation theory and the impact theory, which speculates that the Moon formed from the debris that resulted from a collision between the early Earth and a planetesimal.\n\nThe coformation or condensation hypothesis posits that the Earth and the Moon formed together at about the same time from the primordial accretion disk, the Moon forming from material surrounding the coalescing proto-Earth, similar to the way the planets formed around the Sun. Some suggest that this hypothesis fails to adequately explain the depletion of iron in the Moon.\n\nRecently, the giant impact hypothesis has been considered a more viable scientific hypothesis for the moon's origin than the coformation or condensation hypothesis. The Giant Impact hypothesis holds that the Moon formed from the ejecta resulting from a collision between a very early, semi-molten Earth and a planet-like object the size of Mars, which has been referred to as Theia or Orpheus. The material ejected from this impact would have gathered in orbit around Earth and formed the Moon. This hypothesis is bolstered by two main observations: First, the composition of the Moon resembles that of Earth's crust, whereas it has relatively few heavy elements that would have been present if it formed by itself out of the same material from which Earth formed. Second, through radiometric dating, it has been determined that the Moon's crust formed between 20 and 30 million years after that of Earth, despite its smallness and associated larger loss of internal heat.\n\nThe geological epochs of the Moon are defined based on the dating of various significant impact events in the Moon's history. Analysis of craters and Moon rocks show that there was a late heavy bombardment by asteroids around the period 4.0 to 3.8 billion years ago.\n\nTidal forces deformed the once molten Moon into an ellipsoid, with the major axis pointed towards Earth.\n\nIn 2005, a team of scientists from Germany, the United Kingdom, and Switzerland measured the Moon's age at 4.527 ± 0.010 billion years, which would imply that it was formed only 30–50 million years after the origin of the solar system.[6]

Go to Heavens Above.  They have a lot of information about the planets, as well as satellites that have been placed in orbit or sent out into the solar system.\n\nhttp://www.heavens-above.com

a solar system includes the sun, planets & their moons,meteors ,debris, comets  etc. the sun(star) due to gravitational force attracts the planets & other things & it might lead to development of centripital force b/w the sun & the planets.\nthis forms the solar system

Ask the designer of the Solar System he probably know.

It is certainly possible that some of the many tiny moons of the larger, gas giant, planets could have come from the asteroid belt.  Those massive planets' gravitational field are prone to capture a lot of debris from the solar system.\n\nWow, FishRN, it must have taken a lot out of you to copy paste that whole thing from the wikipedia article, so much so that you couldnt even list your source.\nhttp://en.wikipedia.org/wiki/Asteroid_belt
