14.3 Formation of the Solar System

Rotation of the Solar Nebula We can use the concept of angular momentum to trace the evolution of the collapsing solar nebula. The angular momentum of an object is proportional to the square of its size (diameter) divided by its period of rotation (D 2 P) (D 2 P).If angular momentum is conserved, then any change in the size of a nebula must be compensated for by a proportional

Nebular hypothesis

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems) suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets. The theory was developed by Immanuel Kant and published in his Universal

Pluto and Planet Definition. The outermost part of the solar system is known as the Kuiper belt, which is a scattering of rocky and icy bodies yond that is the Oort cloud, a zone filled with small and dispersed ice traces.These two locations are where most comets form and continue to orbit, and objects found here have relatively irregular orbits compared to the rest of

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests the Solar System is formed from gas and dust orbiting the Sun which clumped up together to form the planets. The theory was developed by Immanuel Kant and published in his Universal Natural History and Theory of the Heavens

6.4: Origin of the Solar System

While cannot rewind time and watch the formation of the Solar System form the beginning, we can look at the Solar System as it is today for clues as to its origins. From that, we can develop a model to describe how it may have gotten that way. 6.5.1 Nebular Theory. According to nebular theory, one of these clouds began to contract. The

How Did the Solar System Form?

· And like that, the solar system as we know it today was formed. There are still leftover remains of the early days though. Asteroids in the asteroid belt are the bits and pieces of the early solar system that could never quite form a planet. Way off in the outer reaches of the solar system are comets.
