Earth’s twin

Venus is often called earth’s twin because it is nearly the same size as earth. But it is really nothing like our world! Firstly, the thick clouds are made of droplets of sulphuric acid – a chemical so strong it can dissolve metal. The winds in venus blow harder than the strongest hurricane on earth. The sky is constantly li by lightning, wich flashes as often as twenty times a minute. The atmosphere is hotter than that in mercury because it traps heat from the sun – like a greenhouse.
