Telling that Betelgeuse, Phobos and Deimos are on the same comparison. Phobos and Deimos don't even make the top 90 known bodies in our solar system 200 miles in diameter, but Betelgeuse is 5.5 ly in diameter and over 600 ly away.

    - Well, Betelgeuse's size and distance is still in debate with estimates varying widely - SteveS - 10/15/2013 1:58:58 PM
      - Granted. We know little about the accurate dimensions of the disc, - ER - 10/15/2013 4:36:05 PM
        
        Oh that - SteveS - 10/15/2013 8:11:06 PM

  - Do you find it odd that the sun and the moon have almost the same apparent diameter? - RobVG - 10/15/2013 1:52:53 AM
    - Its a coincidence. - ER - 10/15/2013 2:59:16 AM
      - Its also a coincidence there's a bright star near the N pole. - ER - 10/15/2013 3:07:13 AM
        
        And a temporary coincidence at that. - TB - 10/15/2013 3:32:27 AM
        
        Gibbous this day our daily bread. - ER - 10/15/2013 4:02:45 AM
