Mars and Venus

Mars and Venus are Earth's neighboring planets in the Solar System, each distinct in characteristics. Venus, often called Earth's "sister planet," has a thick, toxic atmosphere dominated by carbon dioxide, resulting in extremely high surface temperatures—hot enough to melt lead. It rotates very slowly and backward compared to most planets. Mars, known as the "Red Planet," has a thin atmosphere mostly of carbon dioxide and features the tallest volcano and the deepest canyon in the Solar System. It is colder and drier than Earth, with evidence of past water flows. Both planets are key targets for exploration, offering insights into planetary evolution and the potential for life beyond Earth.
