So what does all of that have to do with people wanting to hide in their rooms for weeks at a time?Īstrologers believe that the Moon, stars, planets, and Sun affect happenings here on Earth and that each planet in our Solar System rules a different aspect of life. Outer planets have less frequent, but longer-lasting, periods of retrograde motion. Mercury and Venus appear to go retrograde when they lap us.īecause Mercury completes its orbit around the Sun in only 88 days, the Swift Planet becomes retrograde three or four times in a calendar year, for about three weeks at a time. If one car is driving faster than the other, the slower car will appear to go backward from the perspective of a person in the faster car, even though the slower car is still going pretty fast in the same direction.įor the inner planets, Mercury and Venus, the mechanism that causes them to turn retrograde is the same, but in reverse. Picture two cars on the highway going in the same direction in different lanes. When the Earth overtakes an outer planet, that planet appears to travel backward, as compared to the stars, for a time. Because of this, the Earth often laps these planets in its journey around the Sun. The outer planets - Mars, Jupiter, Saturn, Uranus, and Neptune - all take longer to orbit the Sun than the Earth does, because their orbits are larger. While the location of the stars relative to the Earth is fixed, at least from our vantage point, the other planets in our Solar System all orbit the Sun at varying speeds.
Mercury and Venus appear to go retrograde when they lap earth.īecause of the Earth’s daily rotation, the objects in the night sky appear to “move” from east to west through the night sky.
