Solar System Formation The solar system is located in one of the spiral arms of theMilky Way galaxy. It was born about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed. Most of the material was pulled toward a central point: nearly all of the solar system’s mas...
The Sun's intense radiation and solar wind cleared away the remaining gas and dust, but only up to a certain distance. Further out, where it was cooler, gas and ice could remain in a gaseous state, resulting in the formation of gas giants like Jupiter and Saturn. Even further, ice gian...
I will go through the solar system formation history with two important phenomena: the NC/CC meteorite dichotomy and the giant planet's dynamical instability. Meteorites display an isotopic composition dichotomy between non-carbonaceous...

The Formation of the Solar System Astronomers estimate that the solar system is somewhere around five billion years old and have several theories regarding its creation. The most common-and most widely accepted-one is the nebular hypothesis. According to this theory, the solar system developed from...
While we do not yet have a wholly complete answer, a consensus has arisen about the most likely series of events that led to the present-day system of the Sun and planets. A key piece of evidence about the origin of the solar system is that all the planets orbit the Sun in the same...
Further Evolution of the System All the processes we have just described, from the collapse of the solar nebula to the formation of protoplanets, took place within a few million years. However, the story of the formation of the solar system was not complete at this stage; there were many ...
Prentice (1978a, b), in his modern Laplacian theory of the origin of the solar system, has established a scenario in which he finds the ratio of the orbita

8.Naturally, there were no humans to observe these processes taking place during the formation of our solar system. But astronomers have seen disks of material surrounding other stars that formed only recently.These are called protoplanetary disks,or proplyds, because it is thought that planets can...
