If you have 1 minute to spare, check this web-comic where three dinosaurs discuss "how much our planet (and life) is worth": http://www.qwantz.com/index.php?comic=1608 cheers, Jose Hi Greg,

In fact, I calculate the maximum possible for our solar system to be 2.7 e15 dollars: 6e6 for your fudge factor 9.1 for the age (using CAI U/Pb value of 4.567 Ga) 5e7 for the visual magnitude (-26.7 from your blog) And all the exponent components fixed to 1.
