Key facts about Venus

• Venus is often called “Earth’s twin” because they’re similar in size and structure, but Venus has extreme surface heat and a dense, toxic atmosphere.
• It rotates very slowly on its axis – one day on Venus lasts 243 Earth days.
• The thick atmosphere of Venus traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system.
• Phosphine, a possible indicator of microbial life, has been observed in the clouds of Venus.
• Unlike the other planets in our solar system, Venus spins clockwise on its axis.
