Atmosphere

Atmosphere, abbreviated as ATM, is the gasses around an object in space (planets and stars).  The earths atmosphere is not its original atmosphere.  Over time it has evolved to what it is today consists of

• Nitrogen - 78.084%
• Oxygen - 20.95%
• Argon - 0.934%
• Carbon Dioxide - 0.036%
• Neon - 0.0018%
• Helium - 0.0005%
• Methane - 0.00017%
• Hydrogen - 0.00005%
• Nitrous Oxide - 0.00003%
• Ozone - 0.000004%
• and smaller traces of other gasses
