The preposition is followed by its object (and words that modify the object in the prepositional phrase). A preposition is a word that occurs before a noun/pronoun in a clause. Preposition means, pre-before and position-the object's location.
The most widely accepted scientific explanation for the formation of the Solar System is called the Solar Nebular Model. According to this model, the entire Solar System formed around 4.5 billion years ago from the gravitational collapse of a small fraction of a giant molecular cloud, also known as a nebula.
The oldest material found in the Solar System is dated to 7000456720000000000â 4.5672Â±0.0006 billion years ago (Gya). By 7000454000000000000â 4.54Â±0.04 Gya the primordial Earth had formed. The formation and evolution of the Solar System bodies occurred along with those of the Sun.
