(I) Modern theory envisages that the Sun and Solar
System evolved from a primitive nebula. (II) About 5
billion years ago, for reasons unknown, this nebula
began to contract. (III) In the outer regions
temperatures remained even lower. (IV) The rotation
then speeded up, causing the cloud to flatten into a
disk. (V) In the densest part of this disk a proton-sun
formed.
