Flybys

poliastro.threebody.flybys.compute_flyby(v_spacecraft, v_body, k, r_p, theta=<Quantity 0. deg>)

Computes outbound velocity after a flyby.

Parameters:
  • v_spacecraft (Quantity) – Velocity of the spacecraft, relative to the attractor of the body.
  • v_body (Quantity) – Velocity of the body, relative to its attractor.
  • k (Quantity) – Standard gravitational parameter of the body.
  • r_p (Quantity) – Radius of periapsis, measured from the center of the body.
  • theta (Quantity, optional) – Aim angle of the B vector, default to 0.
Returns:

  • v_spacecraft_out (~astropy.units.Quantity) – Outbound velocity of the spacecraft.
  • delta (~astropy.units.Quantity) – Turn angle.
