Definition of eccentric anomaly in US English:

eccentric anomaly


  • The actual anomaly of a planet in an elliptical orbit.

    Compare with mean anomaly
    • ‘We need to convert this into the eccentric anomaly, and the formula is cos E = (e + cos n) / (1 + e cos n).’
    • ‘We use Kepler’s eccentric anomaly in order to get explicit equations for the planetary orbits in a solar system.’
    • ‘The maximum difference in Eccentric Anomaly (in radians) will equal the eccentricity of the orbit.’
