Venus is the second planet from the Sun and is the second brightest object in the night sky after the Moon.

Named after the Roman goddess of love and beauty, Venus is the second largest terrestrial planet and is sometimes referred to as the Earth's sister planet due the their similar size and mass. The surface of the planet is obscured by an opaque layer of clouds made up of sulfuric acid.

The rotation of Venus has been slowed and turned against its orbital direction (retrograde) by the strong currents and drag of its atmosphere. It takes 224.7 Earth days for Venus to complete an orbit around the Sun, and a Venusian solar year is just under two Venusian days long.
