About :

About 4.5 billion years ago, a large cloud of gas and dust began to contract under the effect of gravity and to rotate, flattening out. This is the most reliable hypothesis that the solar system originated. The numerous inconsistencies between this theory and observations still cause astronomers to argue, but they agree that in 5 billion years everything will end up in an enormous planetary nebula.
