The most probable theory for the solar system's formation is
A) a capture theory in which the Sun captured objects moving through space,which then became the planets.
B) an encounter in which a passing star ripped off material from the Sun to form the planets.
C) gas and dust clouds condensed to form the Sun,whereas planets formed later within a nebular disk.
D) condensation of a slowly contracting nebula of hot gas,first into planets in the outer region,then into the Sun at the center.

Question

The most widely accepted theory for the formation of the solar system is the nebular theory, which explains the formation of the Sun and planets from a cloud of gas and dust. According to this theory, the solar system started as a spinning disc of gas and dust called a solar nebula. As gravity caused the nebula to condense, it began to heat up and eventually caused the central part of the nebula to collapse and form the Sun. At the same time, smaller clumps of material called planetesimals began to form in the surrounding nebula. Over time, these planetesimals collided and stuck together, eventually forming the planets. This process is called accretion. The gas and dust that remained in the nebular disk eventually formed the rings, asteroids, and comets in the outer parts of the solar system.
