when is neptune retrograde
Intro To Astrology: Neptune Retrograde. The planet Neptune, so named for the Roman god of the sea, is a mysterious planet. When it goes retrograde-- which means the angle from which we view it, it appears to be traveling backwards-- it gets even more mysterious, and begins to bring some mysteries to light. Since Neptune is in retrograde about once per year, and for nearly half the year, it's important to understand these influences.
