1. Different ways we can classify the planets of the Solar System:
  • By distance from the Sun
  • By size
  • By composition
  • By history—when were each of the planets discovered, and how? 
  • By average, how far away are the planets from the sun?
How long does sunlight take to travel all that distance

How long does it take each planet to orbit the Sunin other words, how long are the other planets’ years?
