The celestial body nearest to Earth after the Moon is Venus. Often referred to as Earth's "sister planet" due to similarities in size and composition, Venus is the second planet from the Sun. Its orbit brings it closer to Earth than any other planet at certain times, making it a prominent object in the night sky, sometimes called the "Evening Star" or "Morning Star." Despite its proximity, Venus has a harsh atmosphere filled with sulfuric acid and extremely high temperatures, presenting a stark contrast to Earth's more hospitable conditions.
