Venusega

Venus is the second planet from the Sun, named after the Roman goddess of love and beauty. It is one of the four terrestrial planets, meaning it is a rocky body like Earth. Venus is often called Earth's "sister planet" because of their similar size and mass, although the similarities end there. Its atmosphere is incredibly dense, composed primarily of carbon dioxide, which traps heat and creates a runaway greenhouse effect. This makes Venus the hottest planet in our solar system, with surface temperatures hot enough to melt lead.

The atmosphere is also covered by thick clouds of sulfuric acid, obscuring the surface from view and contributing to its bright appearance in the night sky. Venus rotates very slowly and in the opposite direction to most other planets, a phenomenon known as retrograde rotation. A day on Venus is longer than its year. Despite its hellish surface conditions, scientists are interested in Venus's past, as some theories suggest it may have once harbored liquid water and a more temperate climate. Future missions aim to explore its atmosphere and surface in more detail to understand its evolution and potential for past habitability.
