What is currently our best model for how the asteroid belt was formed? The material that is now in the belt was once many planetesimals kept from growing larger by tidal forces which were then broken apart into asteroids of different materials by collisions .
How was the asteroid belt formed?
The asteroid belt formed from the primordial solar nebula as a group of planetesimals . Planetesimals are the smaller precursors of the 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 is the asteroid belt made up of?
Composition. Most of the asteroids in the Main Belt are made of rock and stone , but a small portion of them contain iron and nickel metals. The remaining asteroids are made up of a mix of these, along with carbon-rich materials. Some of the more distant asteroids tend to contain more ices.
What is the Kuiper Belt quizlet astronomy?
Kuiper belt. A region roughly between the orbits of Neptune and Pluto and contains thousands of icy/rocky bodies . Oort cloud. A spherical cloud full of frozen objects at the very edge of our solar system, containing billions of comets.
Where did the comets or Kuiper Belt objects form quizlet?
The Kuiper Belt is formed from the outer remnants of the solar Nebula, as were the bodies in the Oort cloud . As a result, much of their materials are the same (basically they are comprised of icy planetesimals of varying sizes).
What is the asteroid belt and Kuiper Belt?
The Kuiper Belt is a large structure in our solar system that begins on the edge of Neptune’s orbit . ... The Asteroid Belt lies mainly between the orbits of Mars and Jupiter, with some outlying asteroids known as the Trojans which share an orbit with another planet.
What does the asteroid belt separate?
The asteroid belt separates the inner and outer planets . ... Mars is also known as the “Red Planet.” Pluto is a dwarf planet and its orbit is an oval shape.
How is the Kuiper Belt different from the main asteroid belt and the Oort Cloud?
The Kuiper belt consists of millions of icy comets, although not asteroids, that circle the sun at a fast pace. While the Kuiper belt is disk shaped, the Oort cloud is spherical shaped .
What lies beyond the Kuiper Belt?
2. It’s far out. (But the Oort Cloud extends even farther) The Kuiper Belt shouldn’t be confused with the Oort Cloud, which is an even more distant, spherical region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt.
Will there be an asteroid in 2021?
You might have heard the buzz about an asteroid called 4660 Nereus , coming closest to Earth on Saturday, December 11, 2021. ... The 1,083-foot (330-meter) asteroid will come within 2.4 million miles (3.9 million km) of Earth, still about 10 times farther away than the moon.
How are asteroids made?
How are asteroids formed? Dust particles in the early Solar System collided, forming larger clumps , known as planetesimals. These could grow by attracting more dust with their gravitational fields; some grew large enough to form the planets. Others remained, becoming the asteroids.
Which of the following statement is are correct about asteroid belt?
Answer: Explanation: Most of the asteroids lie between Mars and Jupiter and it is known as the asteroid belt. It is divided into smaller belts and separated by distances known as Kirkwood gaps. These gaps are spaces in which the gravitational attraction of Jupiter prevents any object from maintaining an orbit.
Do asteroids leave asteroid belt?
If an asteroid is captured by the gravitational pull of a planet, the asteroid can be pulled out of the belt and go into orbit as a moon around the planet that pulled on it.
Can we see the asteroid belt from Earth?
Why can’t we see the asteroid belt in the sky like we can see planets and galaxies? Because asteroids don’t produce any visible light like stars and galaxies, and they are far too small and dark to reflect enough sunlight to be seen with the naked eye like the visible planets.
How do current models explain the origin of the Kuiper Belt What role does planetary migration play?
What role does planetary migration play? The Kuiper belt is composed of ice-rich planetesimals that formed outside the orbit of Neptune . During the planetary migration processes, the Kuiper belt lost the majority of its original mass and orbital resonances with jovian planets gave the belt the form it has today.
What are Earth crossing asteroids quizlet?
An asteroid whose orbit crosses that of earth . Earth crossing asteroids are also called Apollo asteroids, after the first asteroid of this type discovered.
What is Oort cloud quizlet?
Oort cloud. The Oort Cloud is an extended shell of icy objects that exist in the outermost reaches of the solar system . It is named after astronomer Jan Oort, who first theorized its existence. The Oort Cloud is roughly spherical, and is the origin of most of the long-period comets that have been observed.
What’s unusual about our moon?
What’s unusual about our Moon? It’s not the largest moon, but it’s surprisingly large relative to the planet it orbits . Fairly circular and in the same plane. Which have more moons on average?
Why do astronomers today think that we have an asteroid belt?
Although there are many asteroids, they are widely spaced (there is lots of space between them). Why do astronomers today think that we have an asteroid belt and not a planet between Mars and Jupiter? Jupiter’s gravity prevented material in that zone from getting together . Typical asteroids are irregularly shaped.
Do all solar systems have asteroid belts?
The vast majority of asteroids in the solar system are found in a region of the solar system out beyond Mars . They form the Asteroid Belt. Others orbit in near-Earth space and a few migrate or are thrown out to the outer solar system by gravitational interactions.
What do asteroids and comets have in common quizlet?
Asteroids and comets are both made of rocky and icy material , but asteroids are larger in size than comets.
Why did the solar nebula flattened into a desk quizlet?
Why did the solar nebula flatten into a disk? The force of gravity from the planets pulled the material downward into a flat disk . It flattened as a natural consequence of collisions between particles in the spinning nebula, changing random motions into more orderly ones.
What is the origin of asteroids and comets according to nebular theory?
According to the nebular theory, what are asteroids and comets? A) They are the shattered remains of collisions between planets . ... It is made of planetesimals that formed beyond Neptune’s orbit and never accreted to form a planet.
What is the likely origin of the asteroid belt between Mars and Jupiter quizlet?
Terms in this set (45) What best describes the likely origin of the asteroid belt between Mars and Jupiter? A planet was prevented from forming by tidal forces from Jupiter.
Does the Kuiper Belt have dwarf planets?
There are bits of rock and ice, comets and dwarf planets in the Kuiper Belt. Besides Pluto and a bunch of comets, other interesting Kuiper Belt Objects are Eris, Makemake and Haumea. They are dwarf planets like Pluto.
