Venus, Earths Lost Twin: Characteristics of Venus

The video explores Venus, a planet once thought to harbor life but now known for its extreme conditions. It discusses Venus's orbit, visibility, and phases, highlighting its brightness and proximity to Earth. Historical observations, such as those by James Cook, helped measure the distance to the Sun. Speculations about Venus's surface ranged from swamps to deserts, but radar in 1961 revealed its slow, retrograde rotation, possibly due to a massive impact.
