Python package providing some planetary bodies informations

Planetbody

This is a Python package providing basic informations for some planetary bodies. Units used are exclusively from the International System of units.

Usage example

# Import package
from planetbody import earth, mars, europa

# Display Mars radiuses
In [1]: mars.radius
Out[1]: {'unit': 'm', 'val': {'a': 3396200.0, 'b': 3396200.0, 'c': 3376200.0}}

# Display Earth volume
In [2]: earth.volume()
Out[2]: {'unit': 'm^{-3}', 'val': 1.0832072662532028e+21}

# Display Europa mass related to Earth
In [3]: europa.mass['val']/earth.mass['val']
Out[3]: 0.00803691778058

#Display Mars Fact Sheet
In [3]: mars.report()
Mars (S IV) is a planet orbiting Sun
