+**Hohmann Transfer Planning**:
+- `calculate_required_separation_for_hohmann()` - computes ideal angular separation between chaser and target at first burn
+- `calculate_wait_time_for_hohmann()` - determines wait time before starting transfer (positive = wait, negative = late)
+- `calculate_next_hohmann_wait_time()` - like above but always returns non-negative by advancing to next phasing opportunity
+- `calculate_relative_orbit_period()` - time between consecutive phasing opportunities
+
+**Maneuver Creation**:
+- `create_hohmann_departure_maneuver()` - adds prograde burn to enter transfer orbit (supports true anomaly or immediate trigger)
+- `create_hohmann_arrival_maneuver()` - adds circularization burn to match target orbit (triggered at target radius)
+
+**Verification**:
+- `verify_hohmann_transfer_orbit()` - checks if current orbit matches expected Hohmann transfer parameters
+- `validate_hohmann_transfer_parameters()` - validates transfer parameters before calculation
+- `hohmann_transfer_complete()` - checks if transfer time has elapsed and spacecraft is at target radius
