Hohmann Transfer Calculator

Find the delta-v for a Hohmann transfer between circular Earth orbits.

Initial orbit radius

Target orbit radius

Total delta-v 3,856.69

First burn 2,399.47

Second burn 1,457.22

Formula: Two burns via an elliptical transfer orbit

Step-by-step with your numbers:

1. Values used:

2. Initial orbit radius = 6,771

3. Target orbit radius = 42,164

5. Total delta-v = 3,856.69

6. First burn = 2,399.47

7. Second burn = 1,457.22

Did we solve your problem today?

A Hohmann transfer is the most fuel-efficient two-burn path between circular orbits.

The math behind it

Burn 1 raises the orbit into an ellipse; burn 2 circularizes it at the target radius. Δv totals the two burns.

LEO (6771 km) to GEO (42164 km) → about 3935 m/s total.

Is it always cheapest?

For coplanar circular orbits, yes — though slower than higher-energy transfers.
