Examples of planetesimal
planetesimal
The last surviving planetesimal populations in the inner solar system are the asteroids.

Geophysical evolution of Saturn's satellite Phoebe, a large planetesimal in the outer Solar System.

Phobos'origin is unclear, and has been identified as a captured asteroid or even the remains of a planetesimal.
From the en.wikipedia.org
Our moon is believed to have been created when a Mars-size planetesimal sideswiped the Earth 4.5 billion years ago.

If that wasn't the answer, a collision with a passing planetesimal could have done the same damage and left the same results.

Their gravity then flung Uranus and Neptune out into the planetesimal disc like bowling balls, causing the objects there to scatter like pins.

Thus, if the majority of the small amounts of water in a planetesimal reaches a planetary surface as its magma solidifies, this would be enough to form oceans that are similar to Earth's.

Eventually, as the gathering rocks compressed into a planetesimal, the heat melted iron and nickel and, being heavy, these elements dropped to Earth's center and pushed lighter rocks up.

- One of many small solid celestial bodies thought to have existed at an early stage in the development of the solar system
- Planetesimals are solid objects thought to exist in protoplanetary disks and in debris disks.
- (Planetesimals) objects, a few kilometers long that were created during the same time the solar system was formed. These objects would either collided to form planets, or become asteroids and comets
- (planetesimals) PLANET PARTICLES, that is, [5:], PO down, FO away, circles NDH [5:], PO down, FO away, from above + (2h)[W], POs up, FOs away, while the thumbs are flicked against the little fingers.
- Term given to objects in the early solar system that had reached the size of small moons, at which point their gravitational fields were strong enough to begin to influence their neighbors.
- Objects that are large enough to gravitationally attract gas, dust and other planetesimals, thus forming larger bodies, and eventually protoplanets. Planetesimals range in size from about 1 km to the size of the Moon.
- In the formative stages of the solar system, a clump of matter massive enough to attract one another gravitationally rather than meeting simply by chance.
- In theory, a small orbiting body that actively accretes mass from random collisions and will eventually become a full-scale planet.
- Tiny, solid pieces of rock and metal that collect in a planetary nebula and eventually accumulate to form a planet.
