Venus is the second planet from the Sun. It is a rocky planet with a mass and size narrowly second in the Solar System to Earth, and with an atmosphere, which is the thickest of all four rocky planets of the Solar System and substantially thicker than Earth's. Its orbit is the next closest to Earth's, orbiting the Sun inferior inside of Earth's orbit, appearing (like Mercury) in Earth's sky always close to the Sun as either a "morning star" or "evening star". In Earth's sky it is also the natural object with the third highest maximum apparent brightness, after the Sun and the Moon, due to its proximity to Earth and the Sun, its size, and its highly reflective global cloud cover.[19][20] Because of these prominent appearances in Earth's sky, Venus has been, particularly among the other four star-like classical planets, a common and important object for humans, in their cultures and astronomy.
