Venus

Venus is the second planet closest to the Sun in the solar system. It is a terrestrial planet and is sometimes referred to as the "sister planet of Earth" because it is the planet most similar in size and average density to Earth in the solar system. It also has the most circular orbit of any planet in the solar system.

From Earth, Venus can only be seen at dawn and dusk, and because it is the third brightest star after the Sun and the Moon, it was treated as the "morning star" at dawn and the "evening star" at dusk. This is because Venus is an inner planet closer to the Sun than Earth, so it does not move very far from the Sun and can only be observed at dawn and dusk when the Sun is still hidden. Its maximum elongation is about 47 degrees, nearly twice that of Mercury, so during those times it can be seen before sunrise or for about three hours after sunset.
