if vernus is between the earth and the sun is that a transit, and why
Yes, if Venus is between the Earth and the Sun, it is known as a transit. A transit occurs when a celestial object, like Venus, passes directly in front of the Sun from the perspective of an observer on Earth. This alignment creates a small silhouette of Venus moving across the face of the Sun.
Transits of Venus are rare astronomical events that happen in pairs eight years apart, with over a century between pairs. The most recent transits of Venus occurred in 2004 and 2012, and the next pair will happen in 2117 and 2125. These events hold significance for astronomers as they provide an opportunity to study certain astronomical phenomena, like accurately measuring the distance between the Earth and the Sun and exploring the atmosphere of Venus by observing how sunlight interacts with it during transit.
