Quiz 16: Unit 8. Part 4. Question 8. Watch the Unit 8 Part 4 lecture video and answer the following question: Why was the International Astronomical Union (IAU) motivated to declassify Pluto as a planet? A) Because it is much smaller than the other major planets B) Because they did not want school children to have to memorize too many planet names. C) Because it does not orbit on the ecliptic of the Solar System D) Because if its orbit were perturbed and it headed into the inner solar system it would develop a tail because of all its ice and we would call it a comet.
B) Because they did not want school children to have to memorize too many planet names.
