A tiny library that calculates the position of the planets.
planetPosition.getPos(2, 2000, {icrf:true})
planetPosition.getPos('jupiter', 2017.101, {circular:true})
planetPosition.getPos("earth", 2100.5, {icrf:true, circular:true})
planetPosition.getPos(0, 2000.7)
getPos(2, 2000, icrf=True)
getPos('jupiter', 2017.101, circular=True)
getPos("earth", 2100.5, icrf=True, circular=True)
getPos(0, 2000.7)
