. 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?
Is a planet different from a star?
Yes it is, and this is because a planet is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.
What planet originated from one of the four protoplanets closest to the sun?
Mars
Which of the following planets originated from one of the four protoplanets closest to the sun?
It was Mercury.
The process by which small debris combines to form planetESimals is called?
Accretion
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.

Why is there a planet?
protoplanets.
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.
Are stars smaller than planetesimals?
No. Stars are many times larger than planetesimals.
What makes planet planet?
protoplanets.
Planetesimals made of ice are called what?
Planetesimals made from ice and sometimes rock are called comets.
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.
How did earth start in its early history?
Earth started when some clouds of discharge from stars collided and compressed. Over millions of years the material eventually compressed and collided to form an area that eventually became smaller and under more pressure due to the increase of gravity at the core. this pulled much of the dust and pebbles to the center but some of the particles came together to form large accumulations with a diameter of a few kilometers. these planetesimals then came together to form the first protoplanets. some of the planetesimals were destroyed in the process or fell into the sun. the next step that occurred was the collision of the protoplanets to form the four inner planets. the outer planets formed in a different way. the whole process is very complicated and took several hundred million years, at least.
What did planetesimals do as earth formed?
As earth formed, most planetesimals were attracted by the earth's gravity and coalesced with earth.
What is a early planet called?
Protoplanets or planet embryos.
