Venus does

Venus is bigger than Mars, almost the same size as Earth. It is covered with a thick dried up lava crust. Venus does have an atmosphere, mostly made up of carbon dioxide (what we breathe out). There is also a thick poisonous cloud cover around Venus, made up of sulphuric acid droplets. Ouch! Venus is the hottest planet, because any heat that gets in to the surface is trapped by those poisonous clouds, like the heat in a greenhouse. Venus is the brightest object in the night sky (besides our moon), because the sun's light reflects really well off those thick acid clouds. A year on Venus is about 225 Earth days. Venus spins very slowly, having about 243 Earth days in one Venusian day. So, it takes longer for Venus to spin on its axis than for Venus to circle the sun!
