   6. (Astrol.) The situation of planets or stars with respect
      to one another, or the angle formed by the rays of light
      proceeding from them and meeting at the eye; the joint
      look of planets or stars upon each other or upon the
      earth. --Milton.
      [1913 Webster]

   Note: The aspects which two planets can assume are five;
         sextile, ?, when the planets are 60[deg] apart;
         quartile, or quadrate, ?, when their distance is
         90[deg] or the quarter of a circle; trine, ?, when the
         distance is 120[deg]; opposition, ?, when the distance
         is 180[deg], or half a circle; and conjunction, ?, when
         they are in the same degree. Astrology taught that the
         aspects of the planets exerted an influence on human
         affairs, in some situations for good and in others for
         evil.
         [1913 Webster]

   8. (A["e]ronautics) A view of a plane from a given direction,
      usually from above; more exactly, the manner of
      presentation of a plane to a fluid through which it is
      moving or to a current. If an immersed plane meets a
      current of fluid long side foremost, or in broadside
      aspect, it sustains more pressure than when placed short
      side foremost. Hence, long narrow wings are more effective
      than short broad ones of the same area.
      [Webster 1913 Suppl.]

   Aspect of a plane (Geom.), the direction of the plane.
