Two planets form a semi-sextile when they are spaced about 30° apart, or half a sextile. It is a light, discreet support — two neighboring energies in the zodiac that help each other out without notable friction, without however offering the marked fluidity of a sextile or a trine.
Angle: 30°. Orb used on this site: 2°.
Nature: classified as neutral — a light support, but not clearly classified as harmonic like the sextile or the trine, whose soft family it nonetheless shares.
