Question 9 9. The motions of comets ans asteroids in our solar system are
predictable because they are
A. smaller than planets
B. nearly spherical in shape
C. in orbit around the sun
D. controlled by Earth's gravity

C . In orbit around the sun

A should be the answer because the more you test an experiment the more data you have to rely on changing the experiment would cause you to have different outcomes making the results different and unreliable so B, C, and D is not going to be the answer Hope this helps
