Detailed explanation-1: -The nebular hypothesis has the sun and planets forming at the same time. According to this model, our solar system began as a gigantic, disc-shaped interstellar cloud of gases and dust about 5 or 6 billion years ago .
Detailed explanation-2: -The Accretion theory The Sun passes through a dense interstellar cloud and emerges surrounded by a dusty, gaseous envelope. The problem is that of getting the cloud to form the planets.
Detailed explanation-3: -One version of the catastrophic hypothesis: a near collision between the Sun and another star. The catastrophic hypothesis is the now-defunct idea that the planets and smaller bodies of the solar system originated in a violent event involving a collision or near-collision between the Sun and another object.
