Detailed explanation-1: -Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula – a spinning, swirling disk of material.
Detailed explanation-2: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Detailed explanation-3: -Due to conservation of angular momentum-the velocity of rotation of an object around a central axis-the rotational speed of the cloud increased, and it flattened out. Think of pizza dough flattening into an enlarging disk as it’s tossed.
Detailed explanation-4: -It has been theorized for a long time that a disk of rotating circumstellar material will form as a normal consequence of transferring angular momentum during cloud collapse and star formation.
