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.

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. [1913 Webster]
