Planetesimals.
Dust and gas particles in a protoplanetary disk collided and stuck together to form planetesimals, which then collided and accreted to form planets. The process of gravitational attraction and collisions led to the formation of larger bodies within the disk, eventually forming planets.
accretion
It's called accretion.
It's called accretion.
Collider and collision are the noun forms for the verb to collide; collided is the past tense of the verb.
Most moons of planets are believed to form with their planets as the developing planet is surrounded by a disk of debris. Some moons, though, many be captured asteroids or planetoids. Earth's moon is believed to have formed when Earth collided with another planet.
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.
Bigger galaxies. And stars.
The possessive form of the noun "planets" is "planets'."
The protoplanet hypothesis describes the formation of planets from the dust and gas present in the early solar system. It suggests that small planetesimals collided and merged to form larger celestial bodies, eventually leading to the creation of the planets we see today.
Collision is a noun not a verb. The verb form is collide, and the past tense is collided.
This process is called accretion. It involves small particles like rocks, gas, and dust clumping together due to gravity and sticking to each other to form larger bodies like planets. Over time, these bodies continue to collide and grow in size until they become fully formed planets.
