The normal, forward motion of a planet through the zodiac signs (Aries to Taurus to ...). See also Retrograde Zone Info.
for orbital motion in the solar system, motion that is counterclockwise in the orbit as seen from the north pole of the ecliptic; for an object observed on the celestial sphere, motion that is from west to east, resulting from the relative motion of the object and the Earth.
Motion which is in the usual direction. For planets, orbital motion in the same direction as the other planets, or eastward motion among the stars.
Another term for prograde motion.
A planet moving from west to east in celestial longitude is moving direct.
The normal forward motion of a body through the zodiac signs (Aries, Taurus, Gemini, etc.). This is opposite to retrograde motion, in which a planet moves apparently (but not in actuality), backwards.
eastward motion in the sky
If we were above the solar system in the direction of the North pole. All the planets would revolve around the Sun in an anti-clockwise direction. This is called direct motion. Most of the planets, including Earth, rotate directly on their own axes. The exceptions are Venus, Uranus and Pluto which rotate clockwise, that is with retrograde motion. Moons mainly revolve directly about their planets, the main exception is Triton, the largest moon of Neptune.
(1) Rotation or orbital motion in a anticlockwise direction when viewed from the north pole of the Sun (i.e. in the same sense as the Earth); the opposite of retrograde. (2) The East-West motion of the planets, relative to the background of stars, as seen from the Earth.
Movement of a planet in the order of the zodiac signs from Aries to Taurus to Gemini, etc. Retrograde motion is opposite to direct motion.
Planetary motion through the zodiac in the normal order of the signs. The opposite of Retrograde Motion.
Motion that follows the natural order of signs. Proceeding in the order of the signs. In the Ephemeris, the beginning of direct motion after a period of retrograde motion, is marked by the letter D.
