The body being orbited. Choose Custom to enter your own gravitational parameter.
Orbital radius measures from the center of the body. Altitude measures from the surface and requires a known body radius.
Radius of the initial circular orbit measured from the center of the central body.
km
Radius of the target circular orbit measured from the center of the central body. GEO is about 42,164 km for Earth.

Hohmann transfer around Earth: total Δv = 3.854 km/s, flight time 5h 17m 28s.

  • The first burn (Δv₁ = 2.398 km/s) accelerates the spacecraft to enter the transfer ellipse.
  • The second burn (Δv₂ = 1.457 km/s) accelerates it again to circularize at the destination orbit.
  • Transfer ellipse eccentricity is 0.7230: highly elliptical.

Next stepFor co-planar circular-to-circular transfers, the Hohmann transfer is the minimum two-impulse solution. For three or more burns, a bi-elliptic transfer may help for very large radius changes.
