To determine the most important factor for the formation of our planets according to the condensation theory, we need to understand what the condensation theory is.
The condensation theory, also known as the nebular theory, is a widely accepted scientific explanation for the formation of our solar system. It proposes that our solar system began as a large rotating cloud of gas and dust called the solar nebula. Over time, this nebula began to collapse under its own gravity, causing it to spin faster and flatten into a disk shape.
As the solar nebula continued to collapse, the center became hotter and denser, eventually giving birth to our Sun. Meanwhile, the remaining gas and dust in the disk started to come together through a process known as accretion. Tiny dust particles collided and stuck together, forming larger and larger objects known as planetesimals. These planetesimals eventually grew into protoplanets, which later became the planets we know today.
Now, coming back to the question, the most important factor for the formation of our planets according to the condensation theory is the process of accretion. Accretion is the gradual accumulation of matter due to the gravitational attraction between particles. In the context of the condensation theory, it refers to the coming together and sticking of dust particles, leading to the formation of planetesimals, which then evolve into planets.
Therefore, the most important factor for the formation of our planets according to the condensation theory is the process of accretion, where small particles collide and stick together to gradually build up larger celestial bodies.
