There is no scientific hypothesis known as the "photoplanet hypothesis" for the formation of the solar system. The dominant theory for the formation of our solar system is the nebular hypothesis, which explains the following:

1. Formation of a Nebula: The solar system began as a giant cloud of gas and dust called a nebula.

2. Gravitational Collapse: Over millions of years, gravity caused the nebula to collapse, spinning and heating up in the process.

3. Formation of the Sun: As the core of the nebula contracted, it became so hot and dense that nuclear fusion ignited, forming the Sun.

4. Formation of the Planets: The remaining material in the disk around the young Sun began to clump together, forming planetesimals. These planetesimals eventually collided and merged to form the planets.

5. Differentiation: The heat from the Sun and radioactive decay within the planets caused them to differentiate, forming layers of different densities.

The nebular hypothesis is supported by a vast amount of observational evidence, including:

* The orbital patterns of the planets: All planets orbit the Sun in the same direction and on nearly the same plane.

* The composition of the planets: The inner rocky planets (Mercury, Venus, Earth, Mars) have a different composition than the outer gas giants (Jupiter, Saturn, Uranus, Neptune).

* The presence of asteroids and comets: These remnants of the early solar system provide further evidence for the nebular hypothesis.

Conclusion: The photoplanet hypothesis does not exist in the scientific community, and the nebular hypothesis remains the most widely accepted explanation for the formation of the solar system.
