Chris, the "impactor theory" that Phobos and/or Deimos are ejecta from Mars is incorrect. How do we know this? The mechanics (physics) of impact ejecta have been studied in detail, and the pieces ejected into space are constrained to small sizes.

  - re: BTW, try D or T-type asteroids...the C-type label is old Mariner 9 data which has been proven wrong. (n/t) - Chris Vancil - 11/29/2006 8:30:21 AM
  - re: That Phobos and Deimos are captured C-type asteroids is one of several theories...but it would seem not to explain their low density though. (n/t) - Chris Vancil - 11/27/2006 9:36:39 AM
