Venus Facts

  • Venus is the brightest object in the sky after the Sun and the Earth's moon.
  • Ancient humans believed Venus to be two distinct stars, a morning star and an evening star.
  • Venus is named after the Roman goddess of love.
  • Earth and Venus are often called twin planets because of their similar size and position in the Solar System.
  • Venus has no moons nor rings.
  • Scientists believe that Venus once possessed large amounts of water. However, due to the high temperatures produce from the extreme greenhouse effect, this water boiled off long ago.
  • It takes Venus just under 225 (Earth) days to orbit the sun.
  • Venus has a very, very slow rotation about its axis. One "day" on Venus—the time Venus to complete one rotation—takes 243 (Earth) days. This means that a year on Venus lasts only about 2 days!
  • It rotates counter-clockwise, unlike the other planets in the Solar System.
  • The temperature on the surface of Venus is 462°C (863°F), making it the hottest of all the planets in the Solar System.
  • The temperature on Venus doesn't vary much between the night and day because of the slow movement of the winds across its surface.
  • The surface of Venus is estimated to be between 300 and 400 million years old. Earth's surface is about 100 million years old.
  • Venus has a very weak magnetic field. This surprised scientists, who expected Venus to have a magnetic field similar in strength to Earth's.
  • Venus is the only planet in the Solar System to be named after a female figure.
  • Very little is known about the interior of Venus, but it is thought to have a similar structure to Earth—with a core, mantle and crust—due to its similar size.
  • Venus orbits the sun in an ellipse, but its orbit is the closest to being a circle out of all the planets in the Solar System.
  • When Venus is in line with Earth and the sun, it is the closest planet to us, at an average distance of 41 million kilometers (25.5 million miles) away.
