The initial size of the solar nebula, from which the Sun and the rest of the solar system formed, is estimated to have been about 1 to 2 light-years in diameter. This vast cloud of gas and dust collapsed under its own gravity, leading to the formation of the Sun at its center and the rest of the solar system from the surrounding material. The nebula was primarily composed of hydrogen and helium, with traces of heavier elements. As it collapsed, it became denser and hotter, eventually igniting nuclear fusion in the core to create the Sun.
