pint.orbital.kepler.eccentric_from_mean(e, mean_anomaly)[source]

Compute the eccentric anomaly from the mean anomaly.

Parameters:

  • e (float) – the eccentricity

  • mean_anomaly (float) – the mean anomaly

Returns:

  • eccentric_anomaly (float) – the true anomaly

  • derivatives (float) – pair of derivatives with respect to the two inputs
