Rotation that is opposite to the common rotation of most objects inthe solar system. Most of the planets rotate counter-clockwise, while Venus andUranus rotate in a retrograde… motion - clockwise. moving backward motion (MORE)
Retrograde orbit is when an an object, like a satellite, goes around another object, like a planet, in the direction opposite the second object's rotation. For example, Neptu…ne's moon Triton goes around Neptune with a retrograde orbit. Rather than orbiting around Neptune in the same counter-clockwise direction Neptune rotates in, Triton orbits Neptune in a clockwise direction. (MORE)
Retrograde neurotransmitters are released from dendrites and alter the activity of neighbouring cells. This process is the opposite of typical neurotransmitters, which are rel…eased from the axon terminal (of a post synaptic neuron) and act on dendrites. Two examples are the gaseous neurotransmitters Carbon Monoxide and Nitric Oxide. (MORE)
Retrograde motion is where a body is moving in the direction opposite to the movement of something else. Not to be confused with apparent retrograde motion. [See related link]… If you were on a child's roundabout and your friend was running alongside in the same direction you were spinning, that would be prograde. If however, your friend turned around and ran the opposite way, that would be retrograde motion. [See related link for a pictorial] In astronomy: .
The Earth and four other planets rotate in the same direction as the Sun does; Prograde. .
Venus and Uranus rotate in the opposite direction; retrograde. Do not confuse this with retrograde revolution , as no planet revolves in the opposite direction to the Sun. (MORE)
In astronomy retrograde is essentially a fancy astronomicalway of saying backward/ opposite rotational spin. A body is said tohave retrograde motion when it rotates in a dire…ction opposite tothe body it orbits. I.E. The Sun rotates counterclockwise. Venushas retrograde motion in relation to the Sun because it rotatesclockwise. In astrology retrograde refers to the apparent backwardmotion of a body in the sky due to the Earth overtaking it in orbitabout the Sun. Retrograde planets are said to express themselvesmore internally in a natal chart and in transit indicate periodswhen the affairs they relate to may resurface to be resolved at alater period when the planet goes direct.

A retrograde motion of an OUTER planet happens when Earths orbitcatches up with and overtakes the planet as Earth orbits the Sun.For Jupiter it is observed to be in retrograde… (moving backwards asmeasured against the fixed stars) motion for 121 days a year. NOTE Jupiter is not actually moving backwards, it just appears to. (MORE)
