This backwards movement, retrograde, is actually an illusion created by our viewpoint here on Earth. It’s created by the different speeds at which the planets orbit the Sun. When the Earth’s orbit overtakes a planet with a slower orbit, we see that planet from a different perspective. As Earth overtakes another planet, let’s say Jupiter ...

On January 1, 2024, Mercury stations and turns direct at 22° Sagittarius 11’D. On January 20, 2024, Mercury leaves the Retrograde Zone at 8° Capricorn 29′.
A transit occurs when Venus reaches conjunction with the Sun whilst also passing through the Earth's orbital plane, and passes directly across the face of the Sun. [citation needed] [note 1] Sequences of transits usually repeat every 243 years, after which Venus and Earth have returned to nearly the same point in their respective orbits.
Jul 31, 2020 · John Shonle. Amherst, New Hampshire. A: The apparent retrograde motion of planets (and other objects) on the sky is an illusion caused by the fact that objects in our solar system orbit the Sun at ...
Apparent retrograde motion. Apparent retrograde motion is the apparent motion of a planet in a direction opposite to that of other bodies within its system, as observed from a particular vantage point. Direct motion or prograde motion is motion in the same direction as other bodies. While the terms direct and prograde are equivalent in this ...
Jun 5, 2012 · Fig: 1: Earth (blue), Venus (grey) and the Sun (orange), not drawn to scale. If Venus’s orbit (black dashed circle sitting inside grey rectangle) were aligned perfectly with Earth’s orbit (blue dashed circle sitting inside light blue rectangle), then every time Venus passed between Earth and the Sun there would be a transit — Venus would appear from Earth to move across the face of the Sun.
