Astronomy : Solar System Exam

A person would weigh less on the moon than on the Earth because...

• the moon has less mass, and therefore less gravity

• the moon has more mass, and therefore less gravity

• the moon has less mass, and therefore more gravity

• the moon has more mass, and therefore more gravity

How does changing the distance of the string in the model represent the orbits of the planets?

• the longer the string means the larger the planet

• the longer the string, the longer the orbit time of a planet

• the shorter the string, the longer the orbit time of the planet

• the shorter the string, the smaller the planet

Do planets affect the sun? Why?

• No. Sun pull on the planets and keep them in orbit.
  
• Yes. Sun pulls on planets, planets pull on Sun
