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 colliding planetesimals theory suggests that planets form through the gradual accumulation and collision of smaller rocky or icy bodies called planetesimals in a protoplanetary disk around a young star. Over time, these collisions lead to the growth of planetesimals into protoplanets and eventually planets. This theory helps explain how planets like Earth and its neighbors in our solar system formed.
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 substances existed as solid flakes within the inner 0.3 of the solar system before planets?
Dust grains, ice particles, and rocky fragments were present as solid flakes in the inner 0.3 AU of the solar system before planets formed. These materials gradually accreted and collided to form planetesimals, which later grew into protoplanets and finally, the inner terrestrial planets we see today.

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?
Dust and condensing material accreted into planetesimals due to gravitational forces pulling these particles together. As they collided and stuck together, they gradually grew in size to become planetesimals. This process eventually led to the formation of protoplanets and, ultimately, planets.
Step by step of nebular hypothesis?
The nebular hypothesis proposes that the Solar System formed from a large cloud of gas and dust called a solar nebula. The steps involved are: gravitational collapse of the nebula, formation of a spinning disk due to conservation of angular momentum, condensation of solids in the disk leading to planetesimals, growth of planetesimals into protoplanets, and finally the formation of the Sun and planets from the protoplanetary disk.
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.

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.
