If I Had a Hundred Dollars

If the mass of everything in our solar system is equal to 100 dollars, how much of the sun, planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune), satellites, and minor elements (comets, asteroids, trans-neptunian objects such as the sister planets Eris and Discordia) be equal to? Here is my guess:

  • Sun: 4 dollars
  • Mercury: 1 dollar
  • Venus: 1 dollar
  • Earth: 1 dollar
  • Mars: 1 dollar
  • Jupiter: 3 dollars
  • Saturn: 2 dollars
  • Uranus: 3 dollars
  • Neptune: 3 dollars
  • Satellites: 1 dollar
  • Minor Elements: 80 dollars
I was very wrong. The real answers:
  • Sun: $99.85
  • Mercury: 0.00002 cents 
  • Venus: 0.0003 cents
  • Earth: 0.0003 cents
  • Mars: 0.00004 cents
  • Jupiter: 10.6 cents
  • Saturn: 3.2 cents
  • Uranus: 0.005 cents
  • Neptune: 0.006 cents
  • Satellites: negligible 
  • Minor Elements: negligible
