  6. So what have we found So Far? 174 Planets with Semi Major axis less than 0.4 AU (Mercury/sun distance) 42 Planets with Semi Major axis between 0.4 AU and 0.85 (inside sol’s life zone) 65 Planets with Semi Major axis between 0.85 AU and 1.4 (inside sol’s life zone) 140 Planets with Semi Major axis 1.4 AU and 640 AU But this isn’t the whole story!

  7. Note: Me= .003 Mj Planets near dwarf stars?

  8. A super Earth? Gliese 876d Star M3 15 lyrs Dist= .02 AU M = 7 ME Gliese 876 b,c in 2:1 orbital resonance
