# This is your Astronomy Tonight podcast. **The Venus Transit of June 4, 1761: When Venus Crossed the Sun's Face** Good evening, stargazers! Today we're celebrating one of the most momentous observations in the history of astronomy: the transit of Venus across the Sun on June 4, 1761! Picture this: it's the 18th century, and astronomers across the globe are absolutely *losing their minds* with excitement. A transit of Venus—where our sister planet passes directly in front of the Sun from Earth's perspective—only happens a handful of times per century. This particular event was the first of a pair occurring eight years apart (the other happening in 1769), and scientists knew this was their golden ticket to solving one of astronomy's greatest mysteries: the actual scale of our solar system. You see, by observing the exact timing and position of Venus crossing the Sun from different locations on Earth, astronomers could use something called parallax to calculate the distance from the Earth to the Sun. This measurement—known as the Astronomical Unit or AU—was like having the cosmic ruler that would measure everything else in space. The 1761 transit sparked what might be considered…
