2016 transit

The 2016 transit refers to the astronomical event when Mercury or Venus passes directly between Earth and the Sun, appearing as a small black dot moving across the Sun’s surface. These transits are rare; Mercury transits occur about 13 times per century, while Venus transits happen in pairs roughly every 120 years. The 2016 transit of Mercury occurred on May 9, offering a rare opportunity for astronomers to study the planet and refine measurements of the Sun’s distance. Such events help scientists better understand planetary movements and improve our overall knowledge of the solar system.
