The nebular theory was proposed in 1755 by the German philosopher Immanuel Kant and was further developed by French mathematician and astronomer Pierre-Simon Laplace in 1796.
The nebular hypothesis was proposed by Immanuel Kant and later developed by Pierre-Simon Laplace in the late 18th and early 19th centuries. It suggests that the Solar System originated from a rotating cloud of gas and dust, known as the solar nebula.

Summary:The Kant Nebular HypothesisFrom wikipedia:"There is evidence that the nebular hypothesis was first proposed in 1734 by Emanuel Swedenborg.[1][2] Immanuel Kant, who was familiar with Swedenborg's work, developed the theory further in 1755.[4] He argued that gaseous clouds-nebulae, which slowly rotate, gradually collapse and flatten due to gravity and eventually form stars and planets. A similar model was proposed in 1796 by Pierre-Simon Laplace.[4] It featured a contracting and cooling protosolar cloud-the protosolar nebula. As the nebula contracted, it flattened and shed rings of material, which later collapsed into the planets.[4] While the Laplacian nebular model dominated in the 19th century, it encountered a number of difficulties. The main problem was angular momentum distribution between the Sun and planets. The planets have 99% of the angular momentum, and this fact could not be explained by the nebular model.[4] As a result this theory of planet formation was largely abandoned at the beginning of the 20th century."Edit : As far as I know, the modern theory of how the Solar System was formedis based on modified version of the "Nebular Hypothesis".So it's not been abandoned after all.Note: But the Laplacian model of it has, as the wikipedia article states.

The Nebular Hypothesis.
There is evidence that the Nebular hypothesis was first proposed in 1734 by Emanuel Swedenborg.Immanuel Kant, who was familiar with Swedenborg's work, developed the theory further in 1755. A similar model was proposed in 1796 by Pierre-Simon Laplace.
Planets can be formed from nebular gases and dusts around a protostar or from the cooling of small stars.
The nebular hypothesis was proposed by Immanuel Kant and later developed by Pierre-Simon Laplace in the late 18th and early 19th centuries. It suggests that the Solar System originated from a rotating cloud of gas and dust, known as the solar nebula.
a nebular creates stars as it caves in by its own gravity!

The answer is Nebular Theory
a cluster of stars.
It was first proposed in 1734 by Emanuel Swedenborg. Originally applied only to our own Solar System, this method of planetary system formation is now thought to be at work throughout the universe. The widely accepted modern variant of the nebular hypothesis is Solar Nebular Disk Model (SNDM) or simply Solar Nebular Model.
