Venus, being much farther away than the moon, will not even remotely cover the sun during this journey. Instead, it will pass across our home star as a small black dot. Nevertheless, this process will result in a slight dimming of the sun, scientists say.
Transits of Venus occur in pairs, eight years apart, once a century. This is the second half of this century’s pairing; the next one doesn’t occur until 2117. The 20th century missed Venusian transits entirely, as the previous pair took place in December 1874 and December 1882.
During a transit of Venus, the sun, Venus and Earth also align in a straight line, according to the website Transit of Venus.
Venus was prominent in many ancient cultures but was especially important to the Mayans in Mexico and Central America. Even without telescopes, the Mayans were able to predict the movements of the spectacular object known popularly as the morning (or evening) star with great accuracy, thousands of years into the future. They may not have mapped a transit per se, but they knew where the planet was going to be, and when.
The Mayans venerated Venus as the basis of the god Kukulkan, elsewhere known as Quetzalcoatl. Unlike its modern, Western interpretation as the planet of love, the glittering orb was at that time associated with war. The Mayans even used its appearance to decide when to wage it. The evening version was especially related to war calculations, notes the website AuthenticMaya.com.
Several buildings in the iconic Mayan cities of Chichen-Itza and Uxmal are oriented toward Venus’s path along the ecliptic, and the planet’s journey to and fro across the sky was calculated as far as 7,000 years into the future. As discoveries in the jungles of Guatemala recently made clear, the calculations were scrawled on a wall in a small room thought to be that of the town’s scribe. Until this discovery was made in March, the Dresden Codex contained most comprehensive writings on Venus from the pre-Columbian era.
