Dear Sebastian, If you use formula: q = a ( 1 - e ) you can calculate a simple: a = q / ( 1 - e) then: P= 3/2 * a of course for e < 1.0. Best regards, Maciej...

Hi Sebastian, ... It's that simple: a=q/(1-e), P=a**3/2 (a - major semi-axis, q - perihelion distance, P - period in years). For example, if we take e=0.990051...
