Origins & Early Life

The planet Venus was first observed in antiquity, and continued with telescopic observations, and then by visiting spacecraft. Spacecraft have performed multiple flybys, orbits, and landings on the planet, including balloon probes that floated in its atmosphere.

Career & Major Achievements

Study of the planet is aided by its relatively close proximity to the Earth, but the surface of Venus is obscured by an atmosphere opaque to visible light. Transits of Venus directly between the Earth and the Sun's visible disc are rare astronomical events.

Enduring Legacy & Impact

The first such transit to be predicted and observed was the 1639 transit of Venus, seen and recorded by English astronomers Jeremiah Horrocks and William Crabtree. The observation by Mikhail Lomonosov of the transit of 1761 provided the first evidence that Venus had an atmosphere, and the 19th-century observations of parallax during Venus transits allowed the distance between the Earth and Sun to be accurately calculated for the first time.

Historical Fact-Check Quiz: Observations and explorations of Venus

True or False: “It is a common misconception that Venus's surface is entirely visible to the naked eye due to its brightness.”

Answer (FALSE ❌): The surface of Venus is obscured by an atmosphere that is opaque to visible light, requiring specialized instruments like radar or visible-light spacecraft imaging to study.
