'''Unitas astronomica''' ('''''ua''''') est unitas intervalli, non ad [[systema Internationale|systema SI]] attiniens, quae longitudinem mediam inter [[Sol|Solem]] et [[Tellus (planeta)|Tellurem]] describit. Unio astronomica internationalis (UAI) anno [[19762012]] hanc unitatem ita definivit: '''1 ua = 149&thinsp;597&thinsp;870&thinsp;700 [[kmm]]'''.<ref>E. V. Pitjeva, E. M.
