pub fn apoapsis_from_semi_major_axis_eccentricity(
semi_major_axis: f64,
eccentricity: f64,
) -> Option<f64>Expand description
Computes apoapsis radius from semi-major axis and eccentricity.
Formula: r_a = a * (1 + e)
Returns None when semi_major_axis is less than or equal to zero, when eccentricity is
outside [0.0, 1.0), or when the input or result is not finite.
