LESSON 4 SCIENCE (ASTEROID)

Is a rocky object that orbits the sun

Asteroid

Characteristics

• Smaller than a planet

• Made of rock, metal, or both

• Travel around the Sun in an orbit

• Found throughout the Solar System

• Usually has an irregular shape

• Has no atmosphere

• Reflect sunlight instead of producing its own
