.. py:function:: compute_flyby(v_spacecraft, v_body, k, r_p, theta=0 * u.deg)

   Computes outbound velocity after a flyby.

   :param v_spacecraft: Velocity of the spacecraft, relative to the attractor of the body.
   :type v_spacecraft: ~astropy.units.Quantity
   :param v_body: Velocity of the body, relative to its attractor.
   :type v_body: ~astropy.units.Quantity
   :param k: Standard gravitational parameter of the body.
   :type k: ~astropy.units.Quantity
   :param r_p: Radius of periapsis, measured from the center of the body.
   :type r_p: ~astropy.units.Quantity
   :param theta: Aim angle of the B vector, default to 0.
   :type theta: ~astropy.units.Quantity, optional

   :returns: * **v_spacecraft_out** (*~astropy.units.Quantity*) -- Outbound velocity of the spacecraft.
             * **delta** (*~astropy.units.Quantity*) -- Turn angle.
