Atmosphere

Written by Jerry Ratzlaff on . Posted in Relativistic Mechanics

Atmosphere 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:

  • Abbreviated as ATM

 

  • 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
