About Venus

Venus is the second planet and the hottest, wrapped in a thick carbon-dioxide atmosphere that traps heat in a runaway greenhouse effect. It spins backwards and so slowly that its day is longer than its year. It is the brightest planet in our sky.

Venus: frequently asked questions

What is Venus?
Venus is a planet in our Solar System, orbiting the Sun at an average distance of 0.72 AU (1.08 × 10⁸ km). Venus is the second planet and the hottest, wrapped in a thick carbon-dioxide atmosphere that traps heat in a runaway greenhouse effect.
How far is Venus from the Sun?
Venus orbits the Sun at an average distance of 0.72 AU, about 1.08 × 10⁸ km. One AU is the Earth-Sun distance, so Venus is roughly 0.72 of Earth's distance from the Sun.
How long is a year on Venus?
Venus takes 225 Earth days to complete one orbit of the Sun, which is one Venus year. By Kepler's third law, bodies farther from the Sun take longer to go around.
How many moons does Venus have?
Venus has no moons.
How big is Venus?
