The thick clouds of Venus are made of carbon dioxide gas and sulphuric acid,
and they reflect sunlight and make Venus shine like a star.


  • the second planet from the Sun is Venus.
  • Its orbit makes it 67 million miles away at the Sun nearest and 68 million miles away at its furthest.
  • sometimes it is called the `Evening Star` – because it can be seen from Earth in the evening, just after sunset.
  • however, it can also be seen before sunrise – its visible at these times because it is quite close to the Sun – `Morning Star`.
  • the hottest planet in the Solar System – surface temperature of more than 470°C.
  • so hot – because of the carbon dioxide in its atmosphere traps the Sun’s heat – this overheating is called a runaway greenhouse effect. (diagram)

Venus:- Greenhouse effect

  • thick clouds hide its surface so well that until the Russian Venera 9 probe landed on Venus in 1975 – it was not known what was beneath the clouds. (wikipedia)
  • pressure on the surface of Venus is 90 times more than our Earth’s pressure.
  • “24 hour / one day” – the time Venus takes to spin around once lasts 243 Earth days – longer than its year, which lasts 224.7 days.
  • Venus is the nearest planet to Earth in size, measuring 7,563 miles in diameter.


Did you know?

  • Venus rotates backwards.
  • the atmosphere of Venus is mostly carbon dioxide gas with thick clouds containing sulphuric acid – giving out by this planet’s volcanoes.

Venus – this planet’s volcanoes

  • the 3¾ miles-high volcano on the surface of Venus is called Maat Mons – it had been created on computer using radar data collected by the Magellan Orbiter, which reached Venus in 1990’s.
