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.
. What was the result of collisions between the early Earth and other smaller protoplanets?
What was the result of collisions between the early Earth and other, smaller 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 different stages of Earth were formed?
The Earth formed about 4.5 billion years ago from a rotating disk of gas and dust surrounding the young Sun. The initial stages saw the accretion of dust particles into planetesimals, followed by the formation of protoplanets. Later, the Earth experienced differentiation, where heavier elements sank to the core, creating distinct layers.
What process is necessary for the formation of the a planet?
The formation of a planet involves a process called accretion, which occurs within a protoplanetary disk made of gas, dust, and other debris surrounding a young star. Small particles collide and stick together, gradually forming larger bodies called planetesimals. These planetesimals continue to collide and merge under the influence of gravity, eventually forming protoplanets, which can further accumulate mass to become fully-fledged planets. This process can take millions to billions of years and is influenced by factors such as distance from the star and the composition of the surrounding material.

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.
Major steps of the formation of earth?
The formation of Earth involved several major steps: 1. Accretion of dust and gas to form planetesimals, 2. Collisions and mergers of planetesimals to form protoplanets, 3. Differentiation of Earth's interior into layers, and 4. Cooling and solidification of Earth's surface to form the crust.
Are stars smaller than planetesimals?
No. Stars are many times larger than planetesimals.
What are protoplanets?
Protoplanets are very small planets, about the size of a moon. Astronomers believe these celestial objects are formed during the creation of a solar system.
