The planet known as the “Earth’s Twin” is

Venus is often referred to as the “Earth’s Twin” due to similarities in size, composition, and proximity to the Sun. These two planets share several characteristics, such as a rocky surface and a comparable mass. However, despite these similarities, Venus has a vastly different and inhospitable environment.

Venus has a thick atmosphere primarily composed of carbon dioxide with clouds of sulfuric acid, creating a runaway greenhouse effect. This extreme heat-trapping atmosphere results in surface temperatures hot enough to melt lead. The atmospheric pressure on Venus is also about 92 times that of Earth, making it a harsh and hostile environment.

While Venus may be considered Earth’s twin in terms of size and composition, studying the differences between these two planets provides valuable insights into the impact of atmospheric conditions on a planet’s habitability. Despite their similarities, Venus serves as a cautionary example of the significant role that atmospheres play in shaping a planet’s surface conditions.
