Two planets form a trine when they are spaced about 120° apart. This is natural harmony: the energies flow easily between them, without friction — often experienced as a gift, an innate ease.
Example: Sun trine Jupiter gives natural confidence, optimism, a talent for expansion and taking initiative. The risk, unlike with a tense aspect: too much ease can lull the motivation to act to sleep.
Angle: 120°. Orb used on this site: 7°.
Nature: classified as harmonic — along with the sextile, the trine is one of the only two major aspects judged fluid by traditional doctrine. Three planets forming three trines between them make up a Grand Trine, a rare configuration judged very favorable.
