Protoplanets are larger bodies in the process of forming into planets, usually by accreting material from a protoplanetary disk. Planetesimals are small celestial bodies that are precursors to planets, often ranging in size from meters to hundreds of kilometers and are believed to be building blocks for planets. Essentially, protoplanets are further along in the planet formation process compared to planetesimals.

What are planetesimals and protoplanets and how are related to one another?
Planetesimals are small solid objects that form in the protoplanetary disk around a young star, while protoplanets are larger bodies that develop from the accumulation and collision of planetesimals. Planetesimals are the building blocks that come together to form protoplanets, and eventually, planets. So, planetesimals are like the "seeds" that grow into protoplanets.

How did planetesimals for planets?
Planetesimals formed through the accretion of dust and ice in the protoplanetary disk surrounding a young star. As particles collided and stuck together, they gradually built up larger bodies through a process called gravitational attraction. Over time, these planetesimals combined to form protoplanets, which eventually coalesced into the planets we observe today. This process was influenced by factors such as temperature gradients, orbital dynamics, and the presence of gas and dust in the disk.
How did planetesimals form plaets?
Planetesimals formed as small solid objects in the early solar system, originating from dust and gas in the protoplanetary disk surrounding the young Sun. Through processes like gravitational attraction and collisional coalescence, these planetesimals gradually collided and merged, creating larger bodies known as protoplanets. Over time, continued accretion and gravitational interactions led to the formation of the planets we see today. This process was marked by a dynamic environment, where both constructive and destructive forces shaped the emerging planetary bodies.
How were planetesimals formed?
Planetesimals formed through the process of accretion in the early solar system, when dust and ice particles in the protoplanetary disk began to stick together due to electrostatic forces and later gravitational attraction. Over time, these small aggregates collided and merged, gradually growing larger as they accrued more material. As planetesimals reached sizes of about a kilometer or more, their gravity became strong enough to attract additional matter, leading to the formation of protoplanets. This process ultimately contributed to the development of planets in our solar system.

Why is there an asteroid belt between Mars and Jupiter?
The asteroid belt formed from the primordial solar nebula as a group of planetesimals. Planetesimals are the smaller precursors of protoplanets. Between Mars and Jupiter, however, gravitational perturbations from Jupiter imbued the protoplanets with too much orbital energy for them to accrete into a planet.

What caused dust and condensing material to accrete into planetesimals?
Gravity probably had some effect, but "van der Waals" forces are thought to have been the main cause, in the early stages. These are electrical forces between atoms, molecules, etc.
Step by step of nebular hypothesis?
1) The solar nebula collapses; 2) The Spinning Nebula Flattens; 3) Condensation of Protosun and Protoplanets; 4) Massive expanding gas clouds; 5) Planetesimals collided and grew with other bodies; and 6) Nebulous clouds form.
What are plantesimals?
Planetesimals are small, solid objects that formed in the early solar system out of dust and gas. They eventually collided and grew larger to become protoplanets, which further developed into the planets we know today. Planetesimals played a crucial role in the formation of our solar system.

Why is there a planet?
protoplanets.
What is the colliding planetesimals theory?
The interaction of earth-orbiting and Sun-orbiting planetesimals (very large chunks of rocks like asteroids) early in the history of the Solar System led to their breakup. The Moon condensed from this debris.
How do the planets form from a solar nebula?
Planets form from a solar nebula through a process called accretion. As the nebula, composed of gas and dust, collapses under gravity, it begins to spin and flatten into a rotating disc. Within this disc, particles collide and stick together, gradually forming larger bodies called planetesimals. Over time, these planetesimals coalesce to create protoplanets, which can further merge to form the planets we see today.
