About Venus

Venus is the second planet from the Sun and the hottest in the solar system, with a surface around 464 °C — hot enough to melt lead. A thick atmosphere of carbon dioxide traps heat in a runaway greenhouse effect, and dense clouds of sulphuric acid hide the surface from view.

Similar in size and composition to Earth, Venus is often called our sister planet, yet it rotates slowly and backwards: its day is longer than its year, and the Sun would rise in the west.

Named after the Roman goddess of love. Known since antiquity.
