What is an asteroid?

• A small particle from a comet or an asteroid

• A large object that orbits a star

• A large rock that orbits the Sun

• A group of planets and other objects that orbit a star

What happens to a meteoroid when it enters Earth's atmosphere?

• It becomes a comet with a tail of gas and dust

• It orbits the Sun

• It burns up and is known as a shooting star

• It causes a crater on Earth's surface

What is a comet primarily made of?

• Gases held together by gravity

• Ice and dust

• A large rock

• Gas, dust, and millions of stars

How do asteroids and comets differ?

• Asteroids are composed mostly of ice and dust, while comets are rocky and metallic.

• Asteroids are typically found in the Kuiper Belt, while comets are located in the asteroid belt.

• Asteroids are solid, rocky objects that orbit the Sun and are found mainly between Mars and Jupiter, while comets are composed of ice, dust, and gas and often have distinctive tails when close to the Sun.

• Asteroids and comets are essentially the same and can be used interchangeably in astronomy.
