That's not what I learned in college. So, unless Mercury grew or Pluto shrank, one of us learned wrong.Originally Posted by Levian
We were taught, in college, that Mercury was the smallest planet, and at that time, Pluto was still a planet, though by the end of the semester, it wasn't anymore.
EDIT: Come to think of it, we learned all that same information in high school, middle school, and elementary school. So, unless all of my schools were out to misinform me, which is highly unlikely, then Mercury is smaller than Pluto.
