Solar System Formation – Astrobiology

Solar System Observations. Any theory of solar system formation must be able to explain all of the properties of existing solar systems. This includes not only our solar system but the properties of exoplanetary systems in our galaxy. We will stay focused on first explaining the properties of our own solar system, via the solar nebula model.

The origin of the Solar System

The small blobs would have higher rotation than is seen in the planets of the Solar System, but the theory accounts for this by having the ''planetary blobs'' split into planets and satellites. However, it is not clear how the planets came to be confined to a plane or why their rotations are in the same sense.

The idea that the Solar System originated from a nebula was first proposed in 1734 by Swedish.

Although the nebular theory is widely accepted, there are still problems with it that astronomers have not been able to resolve. For example, there is the problem of tilted axe.

Ideas concerning the origin and fate of the world date from the earliest known writings; however, for almost all of that time, there was no attempt to link such theories to the existence of a "Solar System", simply because it was not generally thought that the Solar System, in the sense we now understand it, existed. The first step toward a theory of Solar System formation and evolutio.
