Venus’ Atmosphere : 

Venus’ Atmosphere Venus’ Surface Is Surrounded By A Thick, Cloud-filled Atmosphere, Which Permanently Hides Venus’ Surface From View.  The Light-Reflecting Clouds In Venus’ Atmosphere, Combined With Its Proximity To Both Earth And The Sun, Are Responsible For Its Brilliant Appearance In The Evening And Morning Sky. The crushing atmosphere contains 96% carbon dioxide, and 4% nitrogen. Back
