Which of the following BEST describes the shape of each planets orbit?

• circle

• elliptical

• sphere

• rectangular

Why is a year on the outer planets much longer than a year on the inner planets?

• they are larger

• they are closer to the sun

• they have a larger orbit since they are further from the sun

• a year is the same amount of time on all planets

Why do all planets orbit the sun?

• The sun is very large and has a weak gravitational pull, so the planets stay close to it

• The sun is smaller than the planets and has a large gravitational pull that attracts the planets

• The sun is large and has a large gravitational pull that makes the planets orbit it

• The sun orbits the planets because it needs to keep them warm
