Venus is the second planet from the Sun, making a full orbit in about 224 days. Venus orbits the Sun at an average distance of about 0.72 AU (108 million km; 67 million mi), and completes an orbit every 224.7 days. It completes 13 orbits in 7.998 years, so its position in our sky almost repeats every eight years.
Kepler's De raris mirisque Anni 1631 Phaenomenis notice to astronomers of the impending transits of Mercury and Venus, 1631. By the 17th century, two developments allowed for the transits of planets across the face of the Sun to be predicted and observed: the telescope and the new astronomy of Johannes Kepler, which assumed elliptical, rather than circular, planetary orbits.

In the second phase, Venus was completely within the sun's disc, but was still "touching" the outer rim. In the third phase, Venus has crossed the sun, was still ...

The transformer was wrapped in foil and painted black and white for thermal reasons.
