Exploring Our Solar System

What is a solar system?

• A collection of galaxies held together by dark matter.

• A collection of celestial bodies, including a central star, planets, moons, asteroids, and comets, held together by gravitational forces.

• A group of stars that form a constellation.

• A single planet orbiting a star.

What forms after the collapse of a nebula in the solar system formation process?

• A black hole.

• A rotating protoplanetary disk.

• A galaxy.

• A constellation.

In the solar system formation process, what does the central mass of the protoplanetary disk become?

• A planet.

• A moon.

• A star.

• An asteroid.

What role does accretion play in the formation of planets?

• It causes planets to explode.

• It helps smaller particles stick together to form larger bodies.

• It prevents planets from forming.

• It causes planets to move away from the star.

How does gravity contribute to the organization of a solar system?

• It pushes celestial bodies away from each other.

• It holds celestial bodies together and influences their orbits.

• It has no effect on celestial bodies.

• It only affects the central star.

What happens to smaller particles in a protoplanetary disk?

• They are ejected into space.

• They coalesce to form planets and other celestial bodies.

• They become stars.

• They disappear.

What is the role of interactions between accretion and gravity in a solar system?

• They cause the solar system to collapse.

• They contribute to the organization and stability of the solar system.

• They have no effect on the solar system.

• They only affect the central star.
