<P> 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 that the Solar System formed from nebulous material . The theory was developed by Immanuel Kant and published in his Allgemeine Naturgeschichte und Theorie des Himmels ( `` Universal Natural History and Theory of the Heavens '' ) , published in 1755 . Originally applied to the Solar System , the process of planetary system formation is now thought to be at work throughout the Universe . The widely accepted modern variant of the nebular hypothesis is the solar nebular disk model ( SNDM ) or solar nebular model . It offered explanations for a variety of properties of the Solar System , including the nearly circular and coplanar orbits of the planets , and their motion in the same direction as the Sun 's rotation . Some elements of the nebular hypothesis are echoed in modern theories of planetary formation , but most elements have been superseded . </P>
