I think you mean "protoplanet hypothesis". In fact, astronomers usually call it the Nebular Hypothesis A protoplanet is a planet-like object that hasn't fully developed into a planet. Why that hypothesis? It's because it is the best we have to describe the origin of the solar system according to the Laws of Physics.
The Solar nebula hypothesis is supported by several lines of evidence, including the observation of protoplanetary disks around young stars, which resemble the proposed structure of our early solar system. Additionally, the distribution of angular momentum in the solar system, with the Sun containing most of the mass and planets forming a flat disk, aligns with predictions of the hypothesis. The chemical composition of the planets, which reflects the solar nebula's materials, further corroborates this model. Lastly, computer simulations of the collapse of gas and dust clouds consistently produce outcomes that resemble the formation of our solar system.

The hypothesis on how the solar system was formed is known as the solar nebula theory. This theory posits that the solar system formed from a massive, rotating cloud of gas and dust called the solar nebula. Over time, gravity caused the material in the nebula to clump together, eventually forming the sun and the planets.

It indicates about the Origin of Solar System as per Nebular Hypothesis.
The most widely accepted model for the formation of the solar system is the nebular hypothesis. This theory suggests that the solar system formed from a rotating mass of gas and dust known as the solar nebula, which collapsed under its own gravity to form the Sun and surrounding planets approximately 4.6 billion years ago.

The nebular hypothesis is the most widely accepted model in the field of cosmogony to explain the formation and evolution of the Solar System (as well as other planetary systems). It suggests that the Solar System formed from nebulous material.
The Solar Nebula Hypothesis was developed independently by Soviet astrophysicist Victor Safronov and American astrophysicist Carl Woese in the 1960s. They proposed that the solar system formed from a swirling cloud of gas and dust called the solar nebula.
The formation of the solar system from a huge cloud of dust and gases is called solar nebular hypothesis. This theory suggests that a rotating disk of gas and dust collapsed under its own gravity, forming the Sun and planets.

The protoplanet hypothesis describes the formation of planets from the dust and gas present in the early solar system. It suggests that small planetesimals collided and merged to form larger celestial bodies, eventually leading to the creation of the planets we see today.
The hypothesis of solar energy states that solar energy will be one of the leading sources of energy in the world in the years to come.
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.
