Compare a three-burn bi-elliptic transfer against the two-burn Hohmann transfer for coplanar circular orbits.
Total delta-v
4.0285 km/s
4,028.5 m/s
Transfer time
135.80 h
5.66 days
Hohmann comparison
-17.8 m/s
lower than Hohmann
Transfer ellipses
108,500 km
second a = 157,500 km
Two transfer ellipses meet at a high apoapsis, creating a three-impulse alternative to Hohmann.
17.8 m/s below Hohmann
