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 collided to form planets with13 letters?

Planetesimals.


The process by which small debris combines to form planetESimals is called?

Accretion.


What did planetesimals do as earth formed?

Planetesimals collided and merged to form the early Earth. This process released a significant amount of heat, contributing to the differentiation of Earth into layers. Additionally, planetesimals delivered water and other volatile materials to Earth, helping to shape its composition.


What are chunks of rock or dust that form comets?

In the "nebular hypothesis", clouds of gas and dust can lead to the formation of "planetesimals". Some of these become comets. So I think the question refers to "planetesimals".


Why isn't there a terrestrial planet form at the asteroid belt?

Jupiter's gravity kept planetesimals from accreting


Are stars smaller than planetesimals?

No. Stars are many times larger than planetesimals.


Planetesimals made of ice are called what?

Planetesimals made from ice and sometimes rock are called comets.


What are planetsimals and how do they form?

Planetesimals, sometimes incorrectly referred to as planetsimals, are thought to form from cosmic dust grains. The dust grains collide with each other and stick to form a larger mass.


What are the small bodies made of rock and ice that became the building blocks for planets called?

They are called planetesimals. These small bodies collided and merged to form larger bodies like planets and moons during the early stages of the solar system's formation.


What effect do collisions among planetesimals of greatly varying size have on the formation of planets?

Collisions among planetesimals of greatly varying size can lead to a process called accretion, where smaller planetesimals combine to form larger bodies. This can be a critical step in the formation of planets, as larger bodies have stronger gravitational pull and can continue to grow through further collisions. However, collisions with very large planetesimals could disrupt the growing planetesimal or lead to fragmentation, affecting the final size and composition of the resulting planets.


What causes planetesimals to stay together forming planets when they collide?

Planetesimals stick together due to gravitational attraction and potentially other forces, such as electrostatic forces or chemical bonds. When two planetesimals collide with enough energy, they can merge and form larger bodies, eventually leading to the formation of planets. The exact mechanisms depend on factors like the size, composition, and relative velocities of the colliding bodies.
