Venus is the second planet from the Sun and our closest planetary neighbor. Similar in structure and size to Earth, Venus spins slowly in the opposite direction from most planets. Its thick atmosphere traps heat in a runaway greenhouse effect, making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. Glimpses below the clouds reveal volcanoes and deformed mountains. The planet is named for the ancient Roman goddess of love and beauty, who was known as Aphrodite to the Ancient Greeks.

Venus is the 2nd brightest natural object in the night sky, with the brightest natural object being the Moon. Being so bright, Venus can cast shadows and can be, on rare occasion, visible to the naked eye in broad daylight.
Venus does not have any moons. It is likely this way because any moon with an orbit too great a distance from Venus would be in an unstable orbit and be captured by the Sun. If moons were too close to these planets they would be destroyed by tidal gravitational forces.
- Being closer than Mars to Earth, Venus has been suggested as a potential option for colonization, albeit with cloud cities, rather than landing on the surface.
- It has the densest atmosphere of the four terrestrial planets, consisting of more than 96% carbon dioxide. The atmospheric pressure at the planet’s surface is 92 times that of Earth, or roughly the pressure found 3,000 feet underwater on Earth.
- Venus has by far the hottest surface of any planet in the Solar System,
